SUMMARY
- .This report summarizes the test specimens, test methods, r.nd results of an investigation of the dynamic characteristics and seismic performance of cable tray systems representative of such systems installed in Comanche Peak Steam Electric Station, Unit 1. Six different single- or dual-tier systems i j with up to five supports and lengths of up to 40 ft were installed and tested on a Seismic Shake Table.
The cable tray- system specimens were all subjected to a series of dyna-mic events, including those corresponding to five of Comanche Peak's Operating Basis Earthquakes (OBE) immediately followed by a single Safe ,
Shutdown Earthquake (SSE). Testing for all specimens also included seismic h' inputs exceeding the SSE amplitudes appropriate to Comanche Peak, typically lI exceeding 1.4 SSE, and reaching up to 1.9 SSE amplitudes.
i All specimens performed well and accepted earthquake loading well above design amplitudes with no loss of function, partial co11aspe, or significant distortion. In addition, the tested systems exhibited modal damping ratios exceeding the values used in design for the OBE and SSE conditions. Key j results are presented below. Extensive detail reaardina the testina of each of the six cable trav systems are incorporated in six data reports bound I separately.
Kev Results ,
i l'
- 1. Five of the six cable tray systems were subjected to earthquake j tests (" fragility events") of 1.4 SSE or areater. Two systems d were subjected to events of 1.8 and 1.9 SEE. Despite these severe events--which followed 5 08E and 1 SSE tests plus other significant
- dynamic tests for each tested system--none of the five test speci-i sens exhibited any form of partial or complete structural collapse
- or significant distortion. There was some local damage in the form of cable tray clamp plastic deformation which occurred only for the highest fragility level inputs. No more than five plastic cable ties failed at loading up to 1.6 SSE.
, 2. A sixth test specimen (Case 6), which had atypical cable tray sup-
) ports except for the slenderness ratio (related to buckling), was q subjected to a series of tests similar to the other five specimens, j; terminating at 1.1 SSE. This specimen exhibited no buckling under j the dynamic loads, nor any other evidence of gross distortion or
- 1. damage, and exhibited no evidence of local damage (tray clamps, I! cable ties),

- 3. All six syst 23 remain;d intcct cnd stablo ct th2 cenclusion of th2 tssts, cnd werG without cignific nt distortion. B sid upon j transducer measurements, cable tray slippage relative to tray sup-ports was generally less than 1/10 in. (single amplitude) for all seismic and system behavior tests. The maximum slippage measured occurred during the fragility tests, and for the most part did not
-i exceed 2/10 in. Oversized bolt holes, less than minimum edge distances, undersized welds, and unused bolt holes had no evident influence on response and were not sources of local failures.
- 4. Modal damping ratios for the cable tray systems >:ere observed to increase with response amplitude. The highest modal damping gener-ally occurred for the 50% fill condition, with higher damping ratios in the lower modes. Construction details--particularly gaps between trays and supports--appeared to have no significance with respect to damping values. -
- 5. For all modes for which damping could be reliably determined (primarily, the transverse modes), seismic modal damping values for the lower modes, and for virtually all tests, exceeded 4% (OBE level) and 7% (SSE level) of critical damping in all cases for which the trays contained 50% or greater cable fill. Lower mode damping values for the tested systems typically ranged from 10% to 20% of critical damping for input amplitudes ranging from 08E to SSE levels for cable tray fill of 50% or more, l

1.0 INTRODUCTION
P j The objective of the Comanche Peak cable tray test program was to I
- investigate the dynamic characteristics of cable tray systems erected of
!! components ' similar to those installed in Comanche Peak Unit 1. Of par-l ticular interest was the effective damping ratio of the systems as a func-
! tion of cable fill levels, response amplitudes, and construction detaile.
U j In addition to damping related tests and determination of frequency
- characteristics, the test specimens were subjected to severe seismic excite-tion up to and substantially exceeding the Safe Shutdown Earthquake (SSE) condition appropriate for Comanche Peak. Dynamic testing was conducted pri--
marily by mounting each of the six test structures--typically consisting of five supports with nine foot spacing supporting one to two tiers of trays j, and cable fill--on ANCO Engineer's Seismic Shake Table and then driving the shake table to provide base motion inputs to the test specimens.
- s 1.1 Test Objectives Specific test objectives were: !
- 1. to verify that 4% of critical damping for the Operating Basis
, Earthquake and 7% of critical damping for the Safe Shutdown ,
Earthquake events were appropriate for the welded structural steel- f j supported cable tray systems at Comanche Peaks
- 2. .to provide justification for higher than the 4% and 7% damping val-
! ues for possible applicationsto Comanche Peaks and
- 3. to provide response data to be used for correlation with analyti- !
I cally predicted system response.
i 1.2 Additional Issues Investinated i
Additional issues investigated in the test program included the i following:
, 1. tray clamp slip under the effects of seismic loadings l 2. potential buckling under dynamic loads of one special cable tray a system configuration (Case 6), to demonstrate that buckling of tray
[ support vertical posts was not a credible failure moder
- l. 3. response information and cable tray systems capacity for five Operating Basis Earthquakes (08E) followed by one safe Shutdown l Earthquake (SSE):

- 5. information regarding the influence upon response of such construc-tion details as gaps between cable tray and tray clamps, oversized and unused bolt holes, and less than standard practice edge dis-tances between a bolt hole and the nearest edge of the structural
, steel member with said hole.
- 1.3 Test Specimens Of the six cable tray systems tested, half were single-tier (one tray I run) and half were double-tier. Single-tier specimens incorporated a 24-in.
-I wide ladder bottom cable tray (T.J. Cope): double-tier added a 12-in. wide ladder bottom tray above the 24-in. wide tray. With the exception on one case, all tier lengths were 40 f t and spanned five supports: Case 6, which focused on the issue of potential vertical post buckling under dynamic loading, consisted of a 22-ft, single-tier spanning three supports.
Two tested systems included curved tiers--either in a vertical or hori-zontal plane--at one end of their runs, while the remaining four systems were straight runs. Variables included in the test programs included tray clamp types, cable fill levels and construction details: support spacing varied somewhat to accommodate curved tiers, l
1.4 Test Methods '
In general, the various cable tray specimens were subjected to the a following types of dynamic excitation:
- 1. Random Base Motion - to obtain transfer function data (response /
input) for determination of system frequencies and modal damping ratios as a function of input amplitude:
- 2. Sine-Dwell Base Motion - to obtain system response shapes at modal frequencies for estimating mode shapes and verifying modal frequen-
- j cies as corresponding to tray modes
't
- 3. Impulse Hammer Tests - to obtain system modal characteristics, par-ticularly accurate mode shapes (eigenvectors): and
- 4. Earthquake Base Motion - to obtain response data for validation of analytical models and determination of seismic modal damping
- f (" seismic tests"), to demonstrate system adequccy for repeated 06E

'l i and SSE inputs (" seismic behavior tests"), and to demonstrate severe loads capacity by " fragility" testing.
The earthquake-base motion tests included tests referred to herein as
" seismic tests", " seismic behavior tests", and " fragility tests". A seismic test sequence, for a given test specimen, consisted of four tests with the input level varying from 0.5 OBE to SSE. The seismic behavior tests were performed using the same time histories as for the seismic tests, gained up a small amount, in a sequence of five OBEs followed by one SSE amplitude test. Following the seismic behavior tests, the fragility tests were run using the same time history as was used for the SSE behavior test, but with it amplified above the SSE condition.
The following sections of this report deal withs cable tray systems and testing methods (Section 2.0): methods.for determination of damping and other system characteristics (Section 3.0): summary of the test results (Section 4.0); and discussion of test program results (Section 5.0).

2.0 CABLE TRAY SYSTEMS AND TESTING METHODS As described in the previous section a total of six cable tray con-figurations (cases) were tested using a variety of test methods (excitation ,
j methods). Each configuration tested was unique--that is, all the cases were different from each other in some way. The system parameters that were r varied from case to case included hanger type / configuration, type of tray (straight or curved), span width (tray size), and tray installation parame-ters (e.g., gap condition, oversized bolt hole). Information on each test case is presented in this section.
- The different types of testing performed were briefly described in the l introduction--random, sine dwell, hammer and earthquake. These methods are discussed in detail in this section, as well as the methods of data acquisi-tion, selecting of data acquisition parameters, and the presentation of a generic test matrix.
2.1 Cable Tray Systems Tested Six different types of cable tray systems were tested--Cases 1, 2, 3, 4, 6, and 7.* The parameters used to define them are listed as follows:
- 1) length of tray system (length of tray run):
- 2) number of tray runs:
- 3) number of tier supports / hangers:
- 4) distance between supports / hangers (unsupported span distance):
- 5) types of tray supports / hangers in systems t
l
- 6) type of tray segments (i.e., curved, ladder bottom):
- 7) types of tray joints (splice connectors):
- 8) tray segment size (dimensions):
- 9) types of tray clamps:
- 10) clamp installation parameters (e.g., gap, no gap, oversized bolt hole, undersized weld)
- Case 5 was deleted because of shake table geometric constraints.

- 12) boundary condition of supports (fixed, pinned *).
- The above parameters can be used to completely specify a given cable tray system. Table 2.1 together with Figures 2.1 through 2.8 define / identify the six cable tray cases as they were built and tested (1,2]. This material is supplemented herein by some additional as-built dimensional data in Appendix A.
2.2 Testina Methods and Data Acquisition All of the cable tray specimens were tested using random-base, sine dwell base, and earthquake-base excitation. Except Cases 1 and 2, all cases were tested using some sort of impact hammer testing. The data for these types of testing was acquired using a variety of methods, discussed below.
2.2.1 Testina Methods--Excitation Types The various methods for testing (methods of excitation) the cable tray systems have already been mentioned above. For all testing methods used, each cable tray system was suspended, one at a time, from ANCO Engineers, Inc. 40-ft long x 15-ft wide x 13-ft deep shake table (actually, a shake frame). For three of the four testing methods (random, sine dwell and earthquake) used, the input (excitation) to the cable tray system was generated by driving (moving) the shake table in three dimensions with hydraulic actuators. The drive signal to the actuators was selected to be either random, sinusoidal (simple harmonic) or earthquake-like. The actuator drive signal was required to produce an earthquake input motion to the shake table with specified spectral properties (the response spectrum for the input motion (test response spectrum, TRS) must have a specified relationship to the required response spectrum (RRS), i.e., for some tests the TRS must envelope the RRS).

Tho dir:ctiCn of actuttien input to th3 shako tCble was ccntrollcd by I
- j the direction of the actuators and .e control signal to each actuator (the i ratio of one drive signal to another). The direction of the inputs to the table for the different types of base motion tests are given as follows
Directions of Input Test Type to Shake Table t Random-base input T/V or L Sine dwell-base input T/V or L Earthquake-base input T/V + L l
l where T, V, and L refer to the transverse, vertical, and longitudinal direc-tions, respectively*: T/V for random and sine-dwell testing indicates that the input motion in the T and V directions is the same (there is no input in the L direction) L for random and sine-dwell testing indicates that the input motion is only in the L directions T/V + L for earthquake testing indicates that the input to the table is three-dimensional.
The earthquake base input tests consisted of the following series of events.
- 1. " Seismic Tests"--a sequence of input time history motions were imposed on the shake table with linear amplitude scaling used
[g such that the resulting table motion response spectra approxi-mated (in sequence) 0.5 OBE, 1.0 OBE, 1.5 OBE and 1.0 SSE response spectra. The sequence of tests were designed to span both the 08E and SSE conditions specified for the test specimens
- I to provide data for comparison to analytical model predictions.
The intent of these tests was to insure that data at appropriate amplitudes was available for comparing to analytical predictions.
- 2. " System Behavior Tests"--an input time history motion from (1) above was amplified such that the resulting table motion response spectra enveloped the 08E or $$E response spectra. At these amplitudes, the test specimens were tested with a series of five OBE events, followed by one SSE event.
'O
- The transverse, vertical, and longitudinal directions are perpendicular to the tray run (between $1 and SA) and in a horizontal plane, vertical--
positive direction is upwards, and along the length of the tray run--
positive direction is in the direction for going from $1 to $4.

- 3. "Frcgility TCsts"--an input time histcry moticn us:d in (1) tbovo was furth:r amplificd such that th2 schicv:d rOCponse sp;ctro j' exceeded the SSE response spectra, in some cases by a factor of
- approximately two. These tests were conducted to demonstrate the ;
existence of significant seismic design margins in the test spe-
! cimens.
l 4
The sequence of base motion testing of the various specimens was as L 4
follows:
, e a series of random base motion tests with the following input amplitudes: 0.05 gras, 0.10 gras, 0.15 gras, 0.20 gres, 0.25 gros,
! 0.35 gras, and 0.45 gras ,
e a series of sine dwell base motion tests (0.10 g peak):
- followed by the execution of " Seismic Tests" (nominal amplitudes were 0.5 08E, 1.0 08E, 1.5 08E and 1.0 SSE);
- " System Behavior" tests enveloping the targeted spectra (5 08E's
- plus 1 SSE); and
[I * " Fragility Tests", typically ranging from a nomfnal value of 1.2 SSE to about 2.0 $$E.
For the earthquake tests, the horizontal transient inputs (T and L I inputs) were selected so their response spectre matched as closely as a possible the horizontal required response spectra. Initially, the two hori-zontal inputs were taken to be equal. Then, the vertical transient input was selected so its response spectra matched the required vertical response spectra. Finally, the transverse / and vertical transient inputs were slightly perturbed in an attempt to better match the corresponding required i response spectra simultaneously. Usually, this resulted in the test l
} response spectra (TRS) for one of the two directions (T and V) matching the U required response spectra (RRS) well, with the TRS corresponding to the ;
i
, other direction being greater than its corresponding RRS. Usually the ver-tical TRS, relative to its RRS, was greater than the transverse TRS, role- ;
1 tive to its RRS.
Il' The three types of base excitation (randon, sine dwell, and earth-
[o quake) had associated excitation time histories which were generated in a ,
p particular way. The random time histories were generated using the
- Hewlett-Packard dual-channel spectrum analyzer. The analyzer has as an out-put a single channel with an associated random signal. The random signal Final Summary Report, Document No. A-000181, Page 9 of 182 t

f was p;cs d thrtugh o low-pass anblogue filt0r to slightly modify it. This
, was done to provide more energy below 40 Hz. The sine dwell signal was pro-i duced by a sinusoidal signal generator.
The earthquake time histories that were used for the testing were ;
provided by the client on magnetic tape. The time histories were generated ,
- , in such a way that their response spectra matched closely the required 3 response spectra in the Ebasco test specification (2). For a given earth-quake level (i.e., OBE) and input direction (i.e., X), three dif ferent site 7
j (soil) conditions were considered--there were three time histories. To
- generate a single time history, ANCO connected the three time histories i
, together with about a 2-second spacing between them with no motion. The f
'l last part of the conglomerate time history was the most severe excitation of 3 the whole history. This was done for each input level and direction. For j , test levels which were different than the 00E and SSE levels, the
] appropriate time histories were linearly scaled up or down as needed, e.g.,
for a 0.5 Ott and 1.4 SSE test the 08E and SSE time histories were gained by 0.5 and 1.4, respectively. The required response spectra were for 4% and 7%
damping for the 00E and SSE level inputs. Their ZPAs and domain of greatest j motion are listed below.

The remaining testing method to be discussed, impact hammer testing, _
does not involve the enforced motion of the shake table using the hydraulic actuators. The actuators were not turned ons hence, the shake table rested i;
- on a set of "hard stops" (fairly rigid structures). Thus, the kinematic l
t modes, excited for the base motion tests, were not excited for the hammer !
ll tests. Even though there may have been some motion at the top of the tray f hangers for the hammer tests, it was so small that the cable tray system l
modes obtained corresponded to en approximately clamped condition at the top of the tray hangers, f} The hammer tests were conducted by attaching a fixed uniaxial I

I rubber hammer c;ntaining a calibrated f;rca transdue:r was u: d to striko l the cable tray system at a large number of points / directions. For each new reference accelerometer location the tray system was repeatedly struck by the hammer. The end result of this testing was mode shapes of the tray systems. Other aspects of this testing method are discussed later in this report.
l Table 2.2 indicates which type of tests were performed for each test Case.
2.2.2 Data Acquisit4on There were three dif ferent types of data acquisition used for the cable tray system tests; they are 1) digital, 2) analog and 3) hammer test results via a spectrum analyzer and couputer. The digital acquisition was done mostly for digitizing the analogue transducer data from the earthquake tests. Sometimes it was used for storage of random and sine dwell test data. The analogue acquisition was used primarily for storage of random and sine dwell test data. The hammer test acquisition was a digital acquisition
( process, but done using a Hewlett-Packard spectrum analyzer as opposed to the Data General computer based digital acquisition system used for the earthquake tests.
The digital data acquisition system used is represented symbolically by part _of Figure 2.9. The process starts with the measuring of various responses by transducers. The andlogue signals are then filtered and amplified. Finally they are digitized and then stored, as a computer file, on a hard disk by the minicomputer system for subsequent analyses. The data can be plotted and, depending on the type of data, used to obtain mode sha-pes, response spectra, Fourier transforms, etc. Some general charac-teristics of the acquisition system components are given in Table 2.3.
Typical acquisition parameter values (i.e., time step) used are given as follows:
Time Step = 0.01 sec.
Acquisition Duration = 40 sec. (earthquake input)
Low-Pass Cutoff Frequency = 42.6 Hz Final Summary Report, Document No. A-000181, Page 11 of 182
I The analtgu) d;to acquisitien system used is repr:s nted by p;rt of j Figuro 2.9. Th2 parts of this figure that are common to both methods of 6 acquisition are the transducers, trunk lines, signal conditioners, filters and amplifiers. The data stored on the FM tape (14 or 28 channel) was ana-I lyzed with the aid of a spectrum analyzer and plotter. The dual-channel spectrum analyzer was used to calculate transfer functions (single input, single output) and Fourier transforms. The data on the FM tape was some-times reproduced, digitized and stored as a digital file on disk. A Honeywell 101 (28 channel) and Sangamo Weston (14 channel) analogue FM tape recorder was used. The data was recorded at 1-7/8 in.-per second record
, speed. The same filter cutoff frequency was used as before, i
l The data for the hammer tests were acquired and processed using a calibrated force hammer and reference accelerometer, Hewlett-Packard dual-channel spectrum analyzer and computer, and Structural Measurement Systems modal analysis software package (Model 3.0). The process followed is illustrated in Figure 2.10.
2.2.3 Transducers Four types of transducers were used for the tests: they were accelerometers, displacement transducers, strain gauges, and load washers.
The accelerometers were used to measure the unidirectional absolute acceleration at points on the shake table and cable tray system. The dis-placement transducers were used to measure absolute and/or relative dis-placements of the table and the test specimens, including tray slippage and elongation of vertical members of supports. The strain gauges were used to determine forces / moments in various members of the tray hangers. Load wash-ers were used to measure the tension in selected bolts. Table 2.4 is a list of the types of transducers used for the tests conducted. Appendix B con-tains specification sheets for the transducers.
2.3 Instrumentation of Cable Trav Systems i
The six cable tray systems tested were instrumented with the four types of instruments described earlier. Transducer locations / directions were indicated for each case by specifying 1) the location along the length of the cable tray run (longitudinal direction), 2) the tray run, and 3) the direction of orientation. The transducers always had a longitudinal loca-1 Final Summary Report, Document No. A-000181, Page 12 of 182
ti:n Ct a tray support cr cidway between two adjac nt supports. This is shown, for a generic cable tray system, in Figure 2.11. As can be seen, a transducer location / direction / type can be specified, in general, by the following:
[S h o 2 Transducer Identifier = lo iTJ Y I O (2-1)
[Sh where I o i a specifies longitudinal transducer location (lM) (e.g., 53, M1):
TJ = tray run on which the transducer is located (i.e., T2);
X or Y = specifies the direction the transducer is oriented ing and A
0_C D = specifies the type of transducer, where A, 0 and L refer to (ol j acceleration, displacement and load cell, respectively.
\L /
When the designation for a transducer is written, the brackets are left off, i.e., MIT2ZO, where this corresponds to the displacement transducer being located at M1 on Tier 2 and oriented in the Z-direction.
There are some variations from the above transducer designator.
Generally, the accelerometers attached to the shake table had, as part of their labels, the label " Table".
f

l possible to find where all the transducers were located for the tests.
{
The vast majcrity of the transducer data cbtained from the tests was of good quality. However, there was some bad transducer data due to 1)

!A this was limited to some strain gauges. The data for which there is
, corresponding saturation is indicated in the data reports (3). The only ,
l test case where there were problems with incorrectly mounted strain gauges ;
! was Case 6. The gauges were mounted on opposite faces of the web of the vertical lengths of channel for the tray hangers. The gauges were then "hard-wired" together to obtain the axial force in the channel members however, they were wired together based on the gauges being located in the correct locations (on the outside f aces of the flanges of the channel).
This lead to incorrect values of the axial forces being obtained--the axial force data for Case 6 should not be used.

3.0 DETERMINATION OF DAMPING AND OTHER SYSTEM DYNAMIC Il PROPERTIES--ANALYTICAL METHODOLOGY o i
\ The TUGC0 cable tray test program. has several goals, one of which is
- . the estimation / determination of damping for the systems tested. The topic of interest,-with respect to damping estimation, is the modal damping for l random and seismic excitation. The modal damping gives an estimate of the. !
! dissipation attributable to a given mode, and the system damping is related-il Q to the dissipation of the system as a whole. These two topics are discussed [
4.
l below. .
t There are some topics related to the issue of damping estimation. They !
are the estimation of: 1) system resonant frequencies and 2) system mode f
shapes. These will be addressed in this section also. All the methods, for- '
f the determination of damping and modal properties, discussed herein are
- ll those used for the final data reduction.
ll 3.1 Determine Modal Danoina From Random Test Data There are a large variety of methods for the estimation of model
- damping (i .e. , half-power, log decrement)(1). Some methods are used with ,
- frequency domain data and others are used with time domain data. For the random test data, the half-power method -(frequency domain approach) was used. The random data used were the transfer function modulus plots. An
, example of the application of this method to a linear single-degree-of- l freedom (SDOF) system is presented first.
j; The formula used in the evaluation of damping is Aq= (3-1) i where Af is the bandwidth of the resonant peak (peak of the transfer func-tion modulus curve) at 70.7% of the maximum peak height and fi is the 11h
- system resonant frequency. This is illustrated in Figure 3.1 for a linear i SDOF system. For multiple-degree-of-freedom (M00F) systems, this method can be applied to all of the modes, one mode at a time. An example of this is 1- presented in Figure 3.2.
hh 4
This method requires that the transfer function curve be fairly smooth at and above the half-power response level (.707 of the peak response) .

- { Smoothness of the curve is dependent upon the number of frequency points across the half-power bandwidth. To obtain modal damping estimates with f' acceptable accuracy, there should be at least five frequency points defining i the curve, for the resonant peak, at and above the half-power level. In i doing the damping calculations, it is usually easily observable as to whether or not there is sufficient resolution to be able to obtain a damping estimate.
- _ An important consideration in calculating modal damping is the selec-tion of the data channels on transducers to be used. This selection is l
!! critical because the data used must represent well a given mode--the data
{ should correspond to some of the largest modal response components. If the f systems were linear and there was no noise in the data, any non-zero modal 3 response component could be used in the calculation of the damping--the same damping estimate would be obtained from each modal component. However, the i systems are slightly nonlinear (i.e., closing of gaps, sliding). This will j result in some distortion, relative to the linear response, of the' modal
! response, with the smallest responses being distorted the greatest. By
- using the largest responses, the effect of this distortion on the estimated
) damping values is minimized. Also, by doing this, the portion of the mode I which has the greatest deformation is used in the damping estimation--the l portion of the mode which has the greatest kinetic energy is used.
- r There are three problems which complicate the task of calculating modal t damping by the half-power method; they are 1) the occurrence of closely spaced modes, 2) the presence of nonlinearities and 3) the presence of j noise. Figure 3.2 clearly indicates that at least two modes are responding.
i The two modes are not closely spaced; their frequencies are 4.2 Hz and 6.9 1
! Hz. This makes the computation of the two damping values easy. However, had the two modes been much closer together (in frequency, i.e., 4.2 Hz and j 4.5 Hz), it may have been impossible to obtain any damping estimates. This type of a situation is shown in Figure 3.3. When this occurs, it is someti-nos possible to obtain an approximate estimate of the damping by estimating what the two frequency response curves look like separately. This is shown-conceptually in Figure 3.4. This was done only when the transfer function curves looked somewhat like that shown in Figure 3.4--there was a predomi-nant peak (i.e., Mode a) and a small side peak. The damping was estimated
!t only for the mode corresponding to the predominant peak. It was done by Final Summary Report, Document No. A-000181, Page 72 of 182 l

peak. The bandwidth was then obtained by using one side of the predominant a
I - peak and the straight tangent line.
l, When nonlinearities are present they can result in transfer function l modulus data that are choppy and have false resonant peaks (peaks that look l like, but are not, resonant peaks). This can make the data reduction very i
i difficult. It is important not to mistake a " nonlinear peak" for a resonant l 1
! peak. An example of this type of situation is given in Figure 3.5--the peak i labeled as " Spike" is not a resonant peak, it is due to nonlinear behavior
,l of the system. Another example of this is given in Figure 3.6. The data presented there is from the numerical simulation of the response of a single-degree-of-freedom system with a bilinear-elastic spring. When the i
excitation was low enough (see Figure 3.6a), the system behaved linearly l however, for high-level excitation the system behaved nonlinearly. In 1 I j calculating the half-power damping, peaks due to nonlinearities were iden-l tified (or at least an attempt was made to identify them). Basically two
! things were looked for during the identification process; they were
- 1) transfer function modulus plots which had features which were similar to 4
j that shown in Figure 3.5 and 2) resonant peaks which disappeared and resp-peered as the random input level was increased (i.e., characteristics of f
a curves in Figure 3.6). It is very di,fficult to always establish which peaks
!a are the result of nonlinearities, i
Noise in signal data can arise from mechanical sources (i.e.,
l
- impacting), electrical sources (i.e., vibration of signal cable, electrical ;
j machinery) and the digitization of analogae data. There was noise in the f transducer data, for the cable tray test program, varying from on the order I
of one percent to 10 percent of the maximum transducer response. This can J
- c result in " choppy" transfer functions, which culd make it difficult to l obtain good model damping estimates. The problem of noise in the data can ;
{ be largely overcome by averaging the data--breaking the transient data up ;
into numerous time domains, performing the Fourier transform calculations f{
j separately for each time domain, and averaging the transform results. The
! noisier the data, the greater the number of averages must be taken (more
, terms are need in the average).

f 3.2 Determine System Natural Frequencies From Random Test Data
- { This subsection describes the approach used to obtain the cable tray system natural (resonant) frequencies. The method involves using transfer
, function plots (modulus and phase plots) for the random test data.
Extensive transfer function modulus plotting was done for a given cable fill (usually 50% fill level) and a given input level (usually 0.25 gras). This was done first for the combined transverse and vertical direction input (T/V-direction input). (All data was reduced for the T/V-direction random input first. Then, the L-direction input data was reduced.) Transfer func-tions were obtained for all the cable tray response channels. The reference channels, for transfer function calculations, were selected from those that corresponded to shake table motion (accelerometers mounted on the shake table) and had the same direction as the corresponding response channels.
The best transfer function modulus plots were selected for detailed study. The plots which were selected as the "best" ones had the most clearly and well-defined resonant peaks which indicated an amplification at resonance typical of structural systems, i.e., for a cable tray system, with
~
the transfer function for the tray and shake table motion, the amplification i should be between about two and five. Transfer function phase plots were then obtained which corresponded to the "best" modulus plots. The phase plots were used to confirm peak frequencies as being resonant frequencies.
- For a linear system, the phase of a transfer function changes by 180' in
- " going through resonance". When the system is nonlinear, the phase change may be anywhere from about 45' to 180'. With the "best" channels (used for obtaining transfer functions) selected for the above specified cable fill and input level, transfer functions corresponding to these channels were obtained for the remaining fill and input (gras) levels. Transfer function phase plots were obtained, using the "best" channels, for each fill level and one input level (generally 0.25 gras). The phase plots were used to confirm peak frequencies as resonant frequencies. It is not necessary to obtain phase plots for all input levels, because the existence of the reso-l nant peaks is, in general, confirmed at the 0.25 gros level.
l Having obtained the transfer function data necessary for natural !
frequency estimation and some of the natural frequency values, the next task was to obtain the natural frequency values for each input (grms) level for l
l l

l each given fill condition. The procedure used, for a given fill condition, was to search through all the transfer function data at one of the lowest 6
input levels, usually 0.05 grms, and determine the value of the lowest natural frequency and the pair of data channels (base input and response channels) which gave the best/ clearest presentation of that frequency. (The other channels, which showed the first resonant peak, were used just to further confirm the first natural frequency.) Using this same pair of chan-nels, the value for the first frequency was then determined for the remaining random input levels. Usually the frequency decreased slightly with increasing input (a softening system). Also, it was possible to obtain a qualitative understanding of the degree of system nonlinearity by observing changes in the shape and amplitude of the transfer function for the best channel pair for the first frequency. The above described process was then repeated for the remaining resonant peaks, one peak at a time.
Once all the natural frequencies for the various input levels had been esti-mated using the transfer function modulus data, the frequencies were con-firmed using the phase plots at a single-input level. Once this was done, the entire process was repeated for the other fill conditions.
An example of part of the above described process is presented below.
Figure 3.7 is transfer function modulus plots for Channel pairs 10/2 and 22/3. The natural frequency being identified is 9.4 Hz. Each channel pair plot is studied to see which plot shows the 9.6 Ha peak the best. For this example, the best channel pair is 10/2. This channel pair is then used to follow the peak frequency through the various input levels (see Figure 3.0).
From the data, it is seen how nonlinear the system iss compare the 0.06 gems I modulus plot with the 0.25 gros plot. Af ter the 9.6 Ha peak has been tracked through the different input levels, it is further confirmed as a resonant peak using the transfer function phase plot for the 0.26 gens input (see Figure 3.8).
The discussion above described how to obtain natural frequencies for the cable tray--shake table combination (both taken together to be a single system). It is important to distinguish between a cable tray system (only) natural frequency and a shake table (only) natural frequency. To do this, Final Summary Report, Document No. A-000181, Page 76 of 102
,. it was necessary to obtain response shapes, which closely approximated mode t'
. shapes, or mode shapes.* The shapes were used to determine if the tray
- I motion, for a given frequency, was due to tray and/or tray support flexure or shake table motion. Obviously, the natural frequencies of interest in l this program are those corresponding to tray system modes. The evaluation-of the shapes / modes to determine which frequencies correspond to tray system
! modes is discussed in Section 3.4. ,

il 3.3 Determine Svs'em Response Shapes ,

!l
- I An important model property of a structural system is its structural l modes (eigenvectors). The modes are characterized by the corresponding mode !
) shapes. The mode shapes indicate what parts of the structure are deforming i
! (displacing) the most and the least, and what area has the greatest stress f and strain. Without looking at a given modes' natural frequency, it is i possible to tell if the mode is a lower or higher mode, i .e., lower modes lg are characterized by low strain energy and large kinetic energy (a large ji amount of mass mobilized). From a mode shape, it is easy to determine the l l direction in which most of the mass is moving. Having experimental mode shapes makes it possible to validate en analytical / numerical model by com- ,
i paring the mode shapes for the prediction and experiment, and then possibly f modifying the model to obtain an improved model.

! There are various methods for o'btaining mode shapes from experiments (2). Two methods were used for this projects they are 1) sine dwell and l 2) hammer. Originally, the sine dwell (base motion) method was to have been
- the only method used to obtain estimates of the cable tray system modes.
{ However, due to some dynamic interaction between the tray system and shake table for some of the sine dwell tests, the mode shapes obtained sometimes
! showed significant involvement of the table motion in them. Thus, hammer J

- t
- t l testing (fixed shake table) was started after the completion of Case 2 testing. This was done to provide mode shape data for use as a supplement to the sine dwell modal data. The sine dwell method was used for all the test cases, except for Case 6 however, the hammer method was used only for Cases 3, 4, 6, and 7. The material to follow will describe both methods used.
- l 3.3.1 Determination of Response Shapes From Sine Dwell Test Data The concept of a response shape arose from the attempt to obtain mode shapes (structural eigenvectors) from experimental sine dwell tests. The idea is to either apply a harmonic force (s) or base motion to a structural system. The dwell or forcing frequency is set equal to a natural frequency for which the mode shape is desired. This excitation causes the desired mode to respond greatly, relative to the other modes (assuming the modes are not closely spaced, in frequency, to the desired mode). A shape, described by the harmonic response of the system, can be determined. The shape, called a response shape, is characterized by the modulus and phase of the steady-state harmonic response of the system. For each measured response quantity (each degree-of-freedom which is monitored) there is a modulus and phase. The modulus gives the magnitude of a given response shape component and the phase is used to determine the sign of the component. Under the right conditions, a given response ' shape can closely approximate a mode shape. This is discussed at length in this section.
If a system is excited with harmonic force (s) or base motion of constant amplitude and direction, the steady-state response is also harmonic and has a frequency equal to the forcing frequency, uf. This is represented by(1]
J rj = Rj cos(uft - $j) (3-2)
- where
- rj = the steady-state harmonic response of the 12 degree-of-freedom in the physical domain for the superimposed motion of all the modes (could be either total or relative)
Rj = the amplitude (modulus) of the 12 responses it is a function of the forcing frequency, Rj = R4 (wf):

The above comment about the phase relationship for undamped modes can be understood by studying Equation 3-3. It was stated that ${ - % = 0' or 1180' for undamped modes. Substituting this into Equation 3-3, and setting of = ej, the following result is founds ri(tsuj) = Rj(wj) cos(wjt - h ) cos($4 - h ) (3-6)

these methods usually use some type of system identification. If the modes are damped modes (complex modes), the phase ' difference $g - $k at a reso-nonce will not be O' or +180'. Lastly, if the system is slightly nonlinear, the shapes of the modulus (as a function of forcing frequency) curves will j be affected,.thus affecting the value of the modulus at resonance, i

l response, including the relative modulus and phase, from the test data. The
)l sine dwell tests were performed to determine the response shapes, using base
- motion excitation. The excitation, at the location of the hydraulic actuators, was either in the longitudinal direction, L, or combined trans-

lI where the cable tray support frames (i.e., S1 through SS) were attached experienced motion in three orthogonal directions. Thus, the problem of determining the relative cable tray motions, with the base of the structural system considered to be at the attachment locations between the tray support frames and the shake table, must be viewed as a three direction (L, T, and V directions) base motion problem.
To address the three direction base motion problem, it is necessary to define the coordinates (see Figure 3.9). The relationship between the coor-dinates is simple. The equations corresponding to each of the three direc-tions are given as follows:
l exiIII
- D x(t) + r (t) (3-8a) r y4(t) = b (t) + r (t) (3-8b) r g (t) = b,(t) + r (t) . (3-8c)
~
where r g , etc. = total response of Node Point i in the x-direction, etc.;
b , etc. = base motion in the x-direction, etc.: and x
r , etc. = relative repponse of Node Point i in the x-direction, etc.
The required task is to determine the modulus and phase for the rela-tive responses. This is done by writing an equation which represents any one of Equations 3-8.
r (t) = b(t) + r * (t) g (3 9) l l
For sinusoidal excitation, the steady-state response of the structural system is given by r (t) = R cos(uf t - $ )
g 4 4 (3-10a) b(t) = 8 cos(wf t - $b) (3-10b) r (t) = R cos(wf t - $ ) (3-10c) l

To determine the relative structural response shapes, use Equation 3-7 and Equations 3-11 and 3-12. '
i In order to apply the above equations, it is necessary to select a base. The base could be at a single node point, including the motions in all three directions, or it could be taken from motions at different node j points. There could be a fair amount of flexibility in the selection of the base points. Since the motion of the cable tray system relative to the shake table was desired, it was important to select a base point (s) on the shake table. A single point was always selected to represent the base motion in the x, y and z directions. This point was usually at the middle support (i.e., Support S3 for a five support system).
l It is also necessary to select the reference phase, $k. This -is il done by . studying Equation 3-7. To calculate a relative response shape, the reference phase must correspond 'to one of the components of the rela-1 tive response shape, i.e., $k
- h , then the pg component of the shape is j R - $ rel) , p el(uj ). The reference phase was always set (w)) cos($

component. j l
It should be noted that in order for Equation 3-10 to be valid, the
! system must be at steady-state--the response must be steady-state harmonic.
In order for this to occur, the forcing frequency and direction of the exci-tation must be constant. The more these things vary, the further away from steady-state the response will be. Slight variations in forcing frequency ,
and excitation direction will produce essentially steady-state response.
The cable tray systems that were tested were attached to the shake j table at either three (S1, S2, and $3) or five (S1 through $5) support Final Summary Report, Document No. A-000181, Page 81 of 182
! points. These support points, Sj, on the shake table were the base input 5 locations to the tray system. During a sine dwell test where the input motion at the hydraulic actuators had essentially a constant forcing fre-l quency and directio% the system consisting of the shake table and tray system achieved steady-state harmonic motion; thus, the motion at the sup-port points, Sj, was steady-state harmonic. With these inputs to the tray system being constant in frequency and direction, the tray system reached steady-state. Then, for those sine dwell tests where the motion at the hydraulic actuators was constant in frequency and direction, a steady-state
, harmonic response condition was reached for the tray system, making it possible to use Equation 3-10 to evaluate the relative motion. This was done for all the sine dwell tests performed and for the identified natural frequencies.
Another issue that needed to be addressed in the obtaining of the response shapes dealt with the fact that some of the modes were close together. When this occurs, the response shapes obtained will generally show this. The motions will probably be incompatible for them to occur in a single mode. To generate these types of motion, it would take the super-position of two or more modes. The individual modes can be separated out of the response shape (net response) in some cases by using physical reasoning, i.e., is the motion the combination of symmetrical and antisymmetrical motion?
The above described sine cwell method for obtaining estimates of the tray system mode shapes was implemented using the computer code SYMPHONY *
[3]. Each template used was benchmarked thoroughly. Each mode shape esti-mate calculated was reviewed to determine if it was consistent with what was known about the tray system (i.e., symmetry of tray system). In some cases, the modes showed a significant coupling between the tray system and shake table. This was especially true for Caso 3--Case 3 was very stiff and had i

!j many of its natural frequencies near those of the shake table. The esti-mated modes which were not consistent with the known physical charac-teristics of the tray systems, including those which showed significant l' interaction with the shake table, were not included in the data set for the data packages and summary report.
3.3.2 Determination of Mode Shapes From Hammer Tests ti There are various types of tests that can be performed to determine structural modes (2). Hammer testing was performed for some of the test
,; cases (Cases 3, 4, 6 and 7). A single hammer was used to apply a single transient force to the structure. The response of the structure was measured. From this type of information the modes shapes were determined.
Two types of hammer tests were performed. The type used most of the time (Cases 3, 6, and 7) was based on determining the elements of the structural transfer function matrix; a linear modal model was then fitted to the transfer function data, and from this an estimate of the modes was obtained.
The other type of hammer test deseloped elements of the transfer function matrix, but no curve fitting was performed, and the method involved only a single hammer impact point.
3.3.2.1 Mode Determination Usino Curve Fittina The curve fitting (parameter estimation) method of hammer testing, to determine structural modes, consists basically of the following:
e determine elements of transfer function matrix, for multi-degree-of-freedom (MDOF) system, by performing hammer testing; and
- use an analytical MOOF linear modal model in the performance of curve fitting to obtain the structural modes.
'l !
There are numerous other steps required to produce and display the final modes in global coordinates (see Table 3.1 and Reference 4--Modal 3.0 soft-were system).
The transfer function matrix is defined by the following equation:
{X(W))=[H(w)]{F(W)} (3-13) where{X(w)}=thevectorofsystemresponses(outputs), ,

! (H(w)) = transfer function matrix; and (F(W)} = the vector of system applied forces (inputs), Fourier transform of.
l A particular element of the transfer function matrix, say H ij, can be found by applying only force Fj and measuring X.i This is seen from the following:
n X g= E H ik k " "i1 1 * *** * "ij j * *** * "in n " "ij j ll H
g(w) = X 4(W)/F j(w) 6 The basic procedure used was to select an accelerometer as a fixed (fixed location) reference and move the force location and direction.
! Sometimes the reference accelerometer was moved. By using a fixed reference and moving the force, the elements for a single row of the transfer function matrix were developed. Once the needed parts of the transfer function had been developed, the curve fitting was performed. The curve fitting can be done using an SDOF or MDOF model. There are various methods for doing this L (e.g., SDOF method quadrature response, circle fitting, etc.). After the curve fitting was completed, the orthogonal modes were " backed-out" using a sorting method.
3.3.2.2 Mode DetM wination Usina Uncalibrated Hammer These hammer tests (used uncalibrated hammer) were somewhat differ-ent from those previously described. They involved using a single fixed-reference accelerometer and a movable (roving) accelerometer. For a given location of the rover (movable accelerometer), the cable tray was hit repeatedly with a rubber mallet. The tray was always hit at the same loca-tion and in the same direction. Transfer function data was obtained, and then the rover was moved to a new location. The process was repeated until the entire cable tray response had been mapped. The magnitude of the compo-
!I nents of a given mode were taken from the moduli of the transfer functions thus obtained. The sign of the components were taken from the phase of the
'i transfer functions. The reference was always placed at a location of large l
The hammer impact-point was always near response for the mode of interest.

single mode (excite a single mode) by selecting an appropriate reference /
impact location. Sometimes this was possible. For Case 4 this method produced good results. For considerably more complex systema, this method would probably not produce as good a result as for Case 4.

i it 4.0 TEST RESULTS--A
SUMMARY
- l-The data for each test specimen (test case) were reduced and the
- { results presented in individual data reports. This section contains a sample of material taken from these reports. It consists of modal proper-ties and observations on the state (condition) of the cable tray systems after the system seismic behavior tests and after the fragility tests.
4.1 Summary of Modal Properties--Resonant Frequencies and Modes The modal properties to be presented are resonant frequencies and modes. Tables 4.1 through 4.6 contain some of the resonant frequency data
- . for the six cases. The tables give the frequencies for the various cable fill levels and for a variety of random base input levels. In all cases the frequencies decreased as the fill level increased.* Because the mass of the tray supports and mass of the trays contributed to the total mass of the tray system, the change in the frequer.cies with a change in the cable fill level was not as large as if the entire mass of the system was due to the cables.
It was not possible to determine the resonant frequencies for modes with their predominant motion in the vertical or longitudinal directions for some test cases (Cases 1, 2, 4, 6 and 7). For some of these cases, it was possible to obtain resonant frequencies with corresponding predominant motions in two of the three directionk (Cases 4 and 7). The reason for this is that for these cases, it was not possible to identify the modes for the corresponding missing frequencies (those that could not be determined).
There were some problems with the interaction between the shake table and the cable tray systems that caused this. This is discussed later in this report.
- Case 3, upon first examination (Table 4.3), appears to deviate from this trend. This appearance is believed due to model " confusion"--inability to identify the same mode in some Case 3 tests. Physical reasoning indicates that resonant frequencies should decrease as the mass is increased (higher percentage of cable fill). Also, gapped conditions can result in model
" confusion".

. In addition to these tables, son:e of the frequency data was plotted as
] a function of random input level (see Figures 4.1 and 4.2). The data was -l 1
plotted for only one fill level; however, the data in the figures is repre- l a \
sentative of what happens at other fill levels. There is a clear 1 softening
- trend for most of the cases, as the excitation level increases.
This is typical of many structural systems where bolted connections, or other non-weldable connectors, are used. The presence of softening for these cases would be due to a small amount of slippage (relative motion of
_l 1 connected parts) at connection locations (i.e., joints between adjacent pieces of tray). It is possible for softening to be the result of plastic deformation, but this is probably not the case for these systems at and below SSE level excitation.
Mode shape estimates were obtained by the two previously described methods (sine dwell and hammer) . Sometimes only one method was used. A sample of the mode shape estimates is given herein (Figures 4.3 through 4.11 and Tables 4.7 through 4.11). The mode shape estimates were used to establish whether or not a given resonant frequency (as seen in the random data) was a cable tray system frequency.
The methods used to obtain the mode shapes could not deal with the situation of closely spaced modes. For sine dwell testing, the steady-state harmonic response modulus (it is a function of the forcing frequency) would have had two or more resonant peaks glose together for this case--the modu-lus at the desired natural frequency would have contributions from two or more modes. Thus, it would not be possible to obtain the modulus corresponding to only the mode of interest. The situation is similar for the hammer testing. However, hammer testing is more flexible than the base motion sine dwell testing--sometimes for hammer testing the load can be applied at locations where only one of two closely spaced modes are excited.
When there were what appeared to be closely spaced modes, in general, no attempt was made to obtain them.
- Softening in a structural system refers to a decrease in the systems' stiffness as the excitation increases. Hardening refers to an increasing of the systems stiffness with an increase of the excitation.

lj 4.2 Summary of Modal Dampino Data--Random and Seismic Input
'?
Two methods of testing were used to obtain estimates of the cable tray
!l systems modal damping--random and seismic testing was used. The damping was I
first estimated for the random data using the half-power method. These damping values which correspond to the frequencies in Tables 4.1'through 4.6 i, are presented in Tables 4.12 through 4.17. The largest damping generally occurred for the 50% cable fill level. The lowest damping generally
, occurred for the 0% and 100% cable fill levels, with the 100% fill level generally having greater damping than the 0% fill level. Figures 4.12 and j: 4.13 are plots of modal damping as a function of random input level. It-is
. clear that, in general, the damping increases with increasing excitation.
Appendix C contains samples of transfer function modulus plots that were l used for the half-power damping calculatio1s. Some of the calculations per-formed are indicated on the plots.
Modal damping calculations were also attempted with the seismic data.
- The approaches for calculating the damping, that were described in the test
!gI procedure, involve the calculation of the transfer function for a variety of i
single inputs (motion of shake table) and single outputs (motion of cable tray system). This'was done for some of the test data (Case 1). It became evident that there were severe problems in obtaining the required transfer function data. The difficulty in obtaining a transfer function laid with 2
the facti that the duration of the input seismic motion was too short to be
! able to perform a sufficient number of averages, in the computational pro-l cess, so the variance of the data would be somewhat minimized, and at the l
same time have enough data points (time points) per average so the estimate I of the average would be good. It was attempted to process some of the data using a different number of averages--1, 2, 4, 8 and 24 averages were used.
Also, different segments of the motion were used; the entire length of data was used (40 seconds) and the-last third of the entire signal was used. A
- detailed study of the statistical properties of the data used was performed.
l- It was concluded that because of the very poor quality of transfer functions 3
obtained from the data already processed (see Figures 4.14 and 4.15), no further transfer functions would be obtained; therefore, no seismic damping values would be obtained by the methods specified in the test procedure.
Since no modal damping calculations were performed with the seismic i
data, an approach was developed for relating the " seismic modal damping" to e

p the " random ' modal damping". This was done by comparing the seismic input l; - with the random input--input response spectra were used. Response spectra were determined for the various test cases for both types of . input. A U variety of cable tray fill levels and excitation levels were used. Plots of the - response spectra wre compared in a frequency domain containing the ,
! first few modes (see Figures 4.16 through 4.18). The results of the com-1 1
- 8 parison are given in Table 4.18. When a random and seismic response spectra match well at and near a resonant frequency, the motion of the corresponding
-mode is at least somewhat similar for the two types of input. This is because the energy being " fed into" the mode is somewhat similar and the peak ~ modal response is similar for both inputs. Thus, it is expected that
+
the energy dissipation for the mode would be similar for both types of input. Thus, Table 4.18 and the damping tables for random input can be used to obtain from fair to good estimates of the seismic damping.
A sample of all the peak input and output data for one of the seismic tests is given in Appendix D. The data reports [1] contain the peak acce-1eration, displacement, strain and load data for all the seismic tests.
4.3 Observation of System Behavior--Earthquake Input (Behavior and Fracility Tests)
Of primary interest in the earthquake tests is 1) damage sustained, if any, 2) buckling behavior of the vertical lengths of channel of the tray
- supports'for Case 6, and 3) system re,sponse data. Tables 4.19 through 4.21 i describe the damage sustained by each test case for the system seismic behe-
- vior tests and fragility tests. There were no system structural failures *
- during any of the earthquake tests (behavior or fragility) for any of the
- cases. There was virtually no damage to Cases 1, 2, 3, 4 and 6 for the seismic behavior tests; there was some minor clamp and very small buckling '
(of curved tray for tray Run 2) damage to Case 7. The fragility level !
i 4
tests produced some modest levels of damage, but only at the higher l levels l of input (i.e., 1.8 SSE). At the lower fragility levels (e.g., 1.2 SSE and l 1.4 SSE) there was virtually no damage.

i l
- Structural failure is defined as general (global) system collapse.
Limited localized in-elastic behavior by itself does not constitute failure.

Test Case 6 was designed with tray' supports having long vertical sec-j' , tions of channel (13' ft). This was done to investigate the buckling beha- l vior of the tray supports with an earthquake input. The visual observation
- of the Case 6 structure after the fragility tests revealed that.there was no noticeable permanent deformation of the vertical segments of channel in the tray supports, indicating that probably no buckling had occurred. By visual observation only, there appears to have been no buckling and no loss of structural integrity.
For each earthquake test conducted, cable tray system input and response data was saved, in digital form, on magnetic tape. In this subsec-tion, illustrative exandples of input and response time histories are pre- '
g sented; also, a comparison is made between select TRS's and the ,
f1, corresponding RRS's. The data is presented, in the order just given,'for Cases 3 and 7 (these were chosen as representative cases). The data for both system behavior and fragility tests ' is presented in' Figures 4.19 through 4.28. A comparison was made for Case 7, 100% cable fill and system behavior SSE input, between the TRS's for all five tray support (hanger) ,
attachment locations on the shake table, in the X, Y and Z directions, and I y the RRS's. Figures 4.29 through 4.31 present the results. The TRS's for a given direction were very similar, particularly below 10 Hz. In all cases, the TRS's enveloped the corresponding RRS's. Appendix D contains all the
- f
] peak tra'nsducer data for a sample of tests for Case 7. It also-contains a i sample of peak acceleration data for'all the test cases. The data reports
[1] contain all the peak acceleration data for the behavior and fragility tests. Appendix D also contains some of the time history plots already pre-
!g sented together with some additional plots. There is one plot per page.

- The random base input level given corresponds to at least a reasonably good match between the response spectra for the random and seismic test results.
The response spectra comparisons were done for three accelerometers located L
on the shake table at S3X, S3Y and S3Z. The headings "08E" and "SSE" refer to the seismic tests at the operational basis and safe shutdown levels, respectively.
- Random response spectra was not obtained.

l j 5.0 GENERAL DISCUSSION OF DAMPING The topics of concern in this discussion are 1) the modal damping of-the. cable tray systems, and 2) the ef fect of the flexible and kinematic motion of the shake table on the response of the cable tray systems.
General statements / conclusions are made about the effect of various design parameters on the calculated damping.
3 5.1 Modal Oampina The damping is of major concern to the test program. As the modal damping was calculated for the many different types of cable tray systems tested, the dependence of the damping on the various parameters used to characterize the tray systems can be determined. The parameters of interest in this discussion are listed as follows:
- excitation level; e cable fill level;
- degree of overall rigidity of test specimen;
- cable tray system installation parameters; and
- direction of predominant modal motion.
The damping data available for this discussion are the modal damping estimates obtained from the random test data. From the plots of normalized modal damping as a function cf random input level (presented in the pre-ceding section) it is observed that, in general, the damping increases with increasing excitation. This is expected because, as the excitation level increases, more small amounts of slipping / sliding and impacting probably occur at bolted and clamped locations *, The slipping gives rise to fric-
. tional energy loss. Also, the small amounts of slipping make possible the closing of gaps, another source of energy dissipation.
- The slipping / sliding and impacting referred to would involve any two sur-faces rubbing against each other (e.g., slip plates sliding against cable trays) or any two parts contacting each other (e.g., a bolt, holding a slip plate in place, moves and contacts the outside surface of a hole in a tray).
)

k The dependence of the modal damping on the cable fill level can be seen in the damping tables in the preceding section. In general, the highest The damping is lower modal damping occurs for the 50% cable fill condition.
for the 0% and 100% fill conditions, with that for the 100% fill case
. generally greater than that for the 0% fill case.
i The rigidity of the cable tray systems seems to have had some influence on the damping for the lowest modes. Some of the test cases which had many
.l similarities, but which also had a few differences that resulted in the
- cases having somewhat different stiffnesses, were compared. Cases 2 and 7 l were compared, and Cases 3 and 4 were compared. Cases 2 and 7 had identical supports and trays, the only difference was Case 7 had curved tray members between support S4 and SS and Case 2 did not. The damping for some of the lowest modes for Case 2 was less than that for Case 7. However, the oppo-site was true for some of the other lower modes. No conclusive statement can be made about the damping being larger for a less rigid system from the Case 2 and 7 data.
Cases 3 and 4 had certain geometrical similarities (one tier, five sup-ports and "L" shaped supports at S2, S3 and SA), but the tray supports were much stiffer for Case 3 than for Case 4, and Case 4 had a curved tray segment, whereas the corresponding tray segment for Case 3 was straight.
There was insufficient Case 3 damping data to be able to make any meaningful comparison between the two cases.
The bulk of the cable tray system natural frequencies obtained from the test program had corresponding modes which had the same direction of predo-minant motion--the transverse, T, direction. Thus, it was not possible to l determine, in general, the influence of the direction of modal motion, par-ticularly the direction of predominant modal motion, on modal damping. From some of the limited data for Cases 3 and 4, it appears that modes with transverse or vertical directions of predominant motion may have similar values of modal damping for some of the test cases and cable fill levels.
It also appears that the damping for modes with a predominantly longitudinal !
direction of motion may be somewhat less than that for other modes. These two statements are, at best, tentative in their specifying any trend in the 4
modal damping for the test cases.
I q Final Summary Report, Document No. A-000181, Page 178 of 182
' Comparisons were made between the 100% cable fill condition without and with " gaps". The damping data was studied and it was found that sometimes the damping was greatest for the gapped case and sometimes it was not.
There was no consistent trend in the data. The results of the overall com-parison show that there is probably no substantial difference in damping between the ungapped and gapped cases.
The smallest seismic modal damping value (obtained by the method described earlier) obtained from the test data, excluding only Case 3*, was 5.6% and 6.5% for the OBE and SSE earthquake levels, respectively. If the single data point 6.5% for SSE input is excluded, the smallest value is then 9.8%. It should be noted that for Case 3, there was virtually no damping data for the first modes (lowest modes) corresponding to predominant motions in the three test directions (natural frequencies T1, V1 and L1).
If only the 50% and 100% cable fill cases are considered, the minimum seismic modal damping values are 5.6% and 6.8% for the OBE and SSE earth-quake levels, respectively (excluding Cases 3 and 6).
5.2 Effect of Shake Table Behavior on Cable Tray Systems The shake table has both kinematic and flexible modes. These modes are excited when forces are applied to the table. During the random-base and sine dwell-base tests the input to the table from the actuators was either in 1) the combined transverse, T, and vertical, V, directions (the two I ~
motions were approximately equal), or 2) the longitudinal, L, direction.
i For this type of input, the shake table kinematic modes excited allowed .
o table motion largely in only the combined transverse and vertical directions or the longitudinal direction. There was only a small to modest amount of rotation of the table for these types of tests. The rotation resulted from the hydraulic actuators being slightly out-of-phase with respect to each I. f other.
l
- Case 6 is not included because its seismic modal damping was not investi-gated.

]
.I For the earthquake tests, the. input to the shake table was in all three
]
R ' directions (T, V and L directions). The kinematic modes which were excited caused the table to translate in three directions and also to undergo some
! modest rotations. Overall, it was possible to generate the required earth- j quake motions for the tests (see Figures 4.29 through 4.31).
In addition to the shake table kinematic modes, some table flexible body modes were excited during the testing. There appears to have been two flexible body modes below 15Hz for the shake table without a cable tray system installed on it. The two modes were at about 6Hz and 13Hz. When a cable tray system was installed on the table these frequencies would have changed somewhat. For those cable tray modes which had their frequencies far away from the frequencies corresponding to shake table modes, there was little problem in identifying that portion of the motion which was due to the tray modes. For those tray modes which were closer to (in frequency) the table modes, sometimes there was some difficulty in establishing the tray modes--physical / engineering reasoning was necessary to isolate the I modal motion for the tray system. Fortunately, there were only two table modes below 15 Hz, which made possible the determination of some of the lowest modes.
It should be noted that response shape data (from the sine-dwell tests) was best for the lower cable fill conditions. This occurred because the lower the mass of the test specimen, the greater are its natural frequen-cies; thus, causing the specimens lowest frequencies to be far away from the fundamental frequency of the table. When the shake table was driven sinu-soidally at the lowest natural frequencies of the specimen, the specimen responded in one or more of its flexible modes, but the table only responded f in some of its kinematic modes. It was possible, for these cases, to remove the base motion (table motion) from the absolute motions of the tray system. ,
When the mass of the specimen was larger (i.e., 100% cable fill), it was difficult to separate out the flexible effects of the shake table to obtain I l
, the fundamental mode of the tray system. This was due largely to the dif-ferent motions of the support points on the shake table [1,2).
I The sine dwell mode shape data that was obtained and of sufficiently good quality to be able to use in this and the data reports, corresponds to low interaction between the shake table and the cable tray systems--the k absolute motion was due to the following:
Final Summary Report, Document No. A-000181, Page 180 of 182
1 e shake table kinematic modes - produces the major part of the input to the tops of the tray hangers; r
e table flexible modes - produces a small, relative to the kinematic modes, part of the input to the tray hangers; and e a single cable tray system mode
- relative to the mounting points for.
6 the hangers on the shake table--produces virtually all of the d flexible motion.
When this happened, it was straight forward to remove the part of the abso--
lute motion due to the table kinematic modes and have the resulting motion due largely to the single flexible cable tray mode. Thus, the frequency and mode shape for the single tray mode would be only slightly modified by the flexible behavior of the shake table. The frequency would be slightly less than it would have been if the table had been rigid. The damping for the single mode would be almost entirely due to the flexible behavior of the tray and associated hardware (i.e., splices). The tray mode damping may have been slightly higher due to the dissipation in the table **.
l The shake table used for testing was a two-dimensional table (two inde-pendent inputs could be used). Had a three-dimensional shake table been i used instead, the test results would have been very similar (see Appendix E). The cable tray system modal properties would have been the same; the only difference would have been how the modes would have been excited.
Still the modal data obtained would hade been very much the same.
J
- The motion was due largely to one mode for the case of widely spaced lli modes.
, ** The damping in a welded steel frame (i.e., shake table) is usually on the order of 0.5% to 1%. This, coupled with the fact that the flexible motion of the table was much less than that for the tray system, tends to indicate that the tray damping was due largely to the tray system--the damping was accurate.

l I
RCO oocuusur, ^-oootsi ,- ^-1
\
This appendix contains select as-built dimensional data (physical dimensions) for the cable tray test cases (Cases 1, 2, 3, 4, 6 and 7). The purpose of the data is to, along with Table 2.1 and Figures 2.1 through 2.8, establish the as-built condition of the six cable tray systems tested by ANCO Engineers, Inc. (ANCO). The data generily consists of portions of Texas Utilities Generating Company (TUGCO) trip reports dealing with trips to ANCO, by TUGC0 staff, to inspect / witness various test cases being erected / installed and tested. (The trip reports are quality assurance documents.) Part of these trip reports involve documentation of the as-built cable tray system dimensions which are indicated in the above referenced figures. Some of this material has not been included in this appendix. The other part of the trip reports are for documenting various construction details (i.e., construction deviations). The complete trip reports are availale through ANCO or TUGCO.
Trip reports were not generated for Cases 1 and 2. In their place, a copy of portions of the test procedure have been included herein. The por-tions included deal with the setup of Cases 1 and 2. The appropriate places in the procedure, dealing with setup, have been signed off by ANCO and the client (TUGCO).

7.0 PROCEDURE l The following represents the testing sequence (procedure) that will be used; however, in the unlikely event of an occurrence that is deemed likely to cause nonacceptance, several contingencies have been provided in ;
Section 9.0. Exercising any of those contingencies will cause a deviation in the test plan that will be noted in the chronological log (Section 10.0). In addition, some of the individual tests that follow may be deleted if, in the judgment of both ANCO and client (or designated client
, representative), the data would not add to an understanding of the system response. Conversely, individual tests may be added if, in the judgment of
, both ANCO and client, the data would be necessary to gain an understanding of the system response. Notations of the deletions / additions will be made in the chronological log. Additional test case (s) may be added to the pro-cedure and appended hereto.

As stated in Section 7.0, the test plan procedure any deviate froa the original plan as test results are recorded and assessed. These contingency test plans will be determined just prior to actual testing, and the results l will be recorded in the chronological log (see Section 10.0). !
Configuration drawings will be provided in the final report. 1 Although no contingencies are anticipated at this tiae, examples are as follows:
- 1. Change of tray to support hold-down clip type due to premature failure.
- 2. Change of input wave fora based on new data.

l 9.0 CONTINGENCIES As stated in Section 7.0, the test plan procedure may deviate from the original plan as test results are recorded and assessed. These contingency test plans will be determined just prior to actual testing, and the results will be recorded in the chronological log (see Section 10.0).
Configuration drawings will be provided in the final report.
Although no contingencies are anticipated at this time, examples are as follows:
- 1. Change of tray to support hold-down clip type due to premature failure.
- 2. Change of input wave form based on new data, i

MEMORANDUM l
TO: G. Howard FROM: Z. T. Shi
, DATE: 14 April 1986 RE: Texas Utilities Generating Company
. Comanche Peak SES Installation Procedure for Test Co_nfiguration 7 l _ _
Ref. 1. Memo from R.A. Keilbach to S. Cockrell, dated July 3, 1985 Ref. 2. Attachment to the correspondence from J.P. Pad-alino to G. Howard, dated April 11, 1986.
l I
The purpose of this memo is to clarify the installation proce-dure for the set-up of the current test configuration 7. There are two concerns to be addressed which are described in the following:
- 1. Effective throat of partial penetration weld for clamp type G.
The attachment of Ref. 2 (DET. B on page 4) showed that 1/8 inch partial penetration weld is required to attach clamp type G to the horizontal tier of the support no. 3, $ anol (
(section A-A on page 1 of Ref. 2).
STS The acceptable welding procedure and requirement in pre-paration of welding were described in the attachment of Ufft PI Reference 1.
By issuing this memo, you are requested to follow the referenced welding procedure exactly (copy attached to this memo), in order to achieve the effect throat of 1/8 inch weld on 1/4 inch thick clamps (Type G).
- 2. The orientation of the horizontal 90 degree band, as shown
()ygggD on the sketch (plan view on page 1 of the attachment to 1 Reference 2), is turned to the left when the cable tray is '
, viewed from support no. I down to the support no. 5 along l the axis of cable tray run. However, for the purpose of l dynamic tests and the test result concern, the orientation of horizontal 90 degree bend can be turned to either side of the horizontal cable tray run.

l Sd.E*T TUCCO i CO.P.ANCHE PEAK SIS - UNIT 2 CTH WELD DESIGN VERITICATION PARTIAL PENETRATION VELDS This is to confirm our telecon regarding effective throat dimentions to be used f or partial penetration tee and corner veld joints on cable tray hangers and supports.
Partial penetration 45' bevel tee and corner veld joints on 1/4" thick clips have been detailed.on design verification drawings to have an effective veld throat of 1/8". This is based on the following considerations: .
- 1. AWS Dl.1 prequalified weld joint BTC-P4a (copy attached) is the applicable weld joint for this thickness of material.
- 2. The ef fective veld throat for partial-penetration groove joints velded per BTC-P4a is S-1/8". where S=%g therefore effective veld throat for the specific joints in question is 1/8".
- 3. Shielded metal are process veld metal deposition characteristics and field welding practices at Commanche Peak provide further assurance of achievement of the designated 1/8" veld throat for these veld joints. :
If there are any cluestions, please call.

On March 17-21, 1986 a trip was made to ANCO Engineering Co., in Culver City, Ca. The purpose of this trip was to perform a follow-up inspection / surveillance of (Case 4) Dynamic Testing of Cable Tray Assemblies and Supports and verify the implementation / corrective action performed by ANCO in response to the discrep-ancies/ deficiencies identified during previous TUGC0 visits. See documents outlined below for details. This inspection / surveillance was performed by B.C.
1 Scott, TUGC0 QA Supervisor, and C.D. Wright, TUGC0 QA Inspector.
A. ANCO Tray / Support Testing Trip Report dated 1-17-86 (Attachment A).
B. TUGC0 QA Audit Report, dated 2-11-86 (Attachment B).
C. TUGC0 QA Trip Report, dated 3-10-86 (Attachment C).
D. TUGC0 QA Stop Work Order #86-001, dated 3-13-86 (Attachant D).
The following is a sumary of the sequence of activities that has been taken as a result / response to item A identified in the aforementioned list.
A. 1. ANCO Tray / Support Testing Trip Report: This report addressed Technical and QA Issues. In response to the technical obser-vations/ recommendations suggested by Site En Representative (Resident) Z.T. Shi, (Ebasco)gineering, requested aTUGCO's re-sponse/ action concerning the eleven (11) technical issues of the referenced report.
ANCO responded by issuing memorandum #1806.01G, dated March 17, 1986. This memo in detail itemized and addressed each of the eleven (11) issues, inclu' ding work sheets, plots, and documenta-tion. (See Attachment E).
The above referenced memo (Attachment E) was reviewed and accept-ed without further coment by TUGCO's Representative , Z.T. Shi, (Ebasco). (See Attachment F)
- 2. In addition to the above response by ANCO to the eleven (11)
{ technical issues, which includes concurrence by Z.T. Shi, 3 (Ebasco), a list of cables / cable numbers was submitted to Site Engineering for review.
Pending further confirmation, authorization to proceed with testing was issued by Site Engineering (R.C. Iotti, Ebasco).
(See Attachment G)

M g, A-000181 pg A-47
I .
l l Trip Report i Page 3 l B. 1. TUGC0 QA Audit TANCO-1, dated 2/11-13/86: During this supple-mental audit of ANC0 Engineering, TUGC0 QA identified three (3) deficiencies. Due to the significance and magnitude of these deficiencies, TUGC0 QA requested a hold point be added to the purchase order imposing a restriction on future ANCO test activ-ities for TUGCO. TMs would allow TUGC0 QA to perform in-spection/ surveillance activities to verify calibration status of l the test equipment and check the configuration set-up prior to performance of the test by AMCO. (See Attachment.B for details)
I C. 1. TUGC0 QA Trip Report, dated 3-10-86: The purpose for this visit I was to perform the required verifications that were added to Rev. 4 of TUGC0 P.O. CPF-12839-S. In summary, this report details the discrepancies first identified during TUGCO's Audit No. TANCO-1 and reflects ANCO's lack of comitment to meet the requirements of 10CFR50, Appendix B, ANCO's Procedures, and TUGCO's Purchase Order requirements. (See Attachment C for details)
- 2. Based on the unsatisfactory results during this visit and due to the continuing significance and magnitude of discrep-ancies/ deficiencies identified in this report, TUGC0 QA issued a Stop Work Order Number 86-001, dated 3-13-86. This Stop Work Order was issued to prevent any additional testing for the TUGC0 job and to allow ANC0 time to develop procedures, and obtain required approvals to satisfy the items delineated in the TUGC0 Stop Work Order No.86-001. (See Attachment D for details)
D. The following is a summary of the items identified in the TUGC0 QA Stop Work Order No.86-001 and the corrective action verifications performed during the March 17-21 visit:
Item 1. ANCO failed to obtain documented approval prior to performing welding on TUGCO's job. ANCO had welded an 8" j channel extension to the Test Specimen for Case #4.
t TUGC0 Drawing 4-4c, did not address welding criteria to be used if deemed necessary, nor did it show the 8" channel
$ extension that had been welded by ANCO. :
Correction Action: Drawing 4-4c, Rev. 1, was issued by 4 TUGC0 Site Engineering to reflect the channel extension and !
welding criteria.
Item 2.
A. ANCO does not have weld procedures established to cover welding activities, or acceptance criteria / qualifications i for personnel performing welding.
I g , A-000181 pg A-48 1

1 Trip Report .
Page 4 Corrective Action: ANC0 developed Welding Procedure No.
A-000166 and submitted to TUGC0 Engineering for review and approval.
Approval of the Weld Procedure A-000166 was granted by TUGC0 Site Engineering 3-18-86. (See Attachment I)
! In addition, a review of the ANCO Weld Procedure A-000166 was perfomed by the TUGC0 Site Quality Engineering Group.
See Attachment J for the results of this review which included QE coments.
ANCO incorporated the QE coments into the welding procedure and re-submitted the revised procedure to TUGC0 Quality
, Engineering for review. Acceptance and approval for this procedure was granted on 3-20-86. (SeeAttachmentK) 1 B. The ANCO welder had a current license from the city of Los Angeles to perfom structural welding, but since there were no other certifications or qualifications available for review, it became questionable whether or not the ANC0 I welder would be qualified / certified to perform the welding on the TUGC0 Test Specimen. (See Attachment L) l Corrective Action: A telephone conversation with the City of Los Angeles Material Control and TUGC0 Site Engineering
" was conducted and based on the results of their conversation it was detemined that a welder certified / licensed by the City of Los Angeles would meet the requirements of AWS.
(See Attachment M) :
In addition, all rework activities performed by ANCO, such as, grinding, weld preparation, fit-up and welding was witnessed by the TUGC0 QA Representative. All rework activities were found to be satisfactory. (SeeSignoff, Attachment N)
Item 3.
A. The TUGC0 drawing #4-4a, Re'. 1, indicated the top angle and lower channel of the Supports 2, 3, and 4 be mounted in a direction that was opposite to the direction of the supports observed by the TUGC0 QA Representative on the Test Stand.
1 Corrective Action: A review of this drawing was performed by TUGC0 Engineering and was amended to state the supports l can be installed in either direction. (SeeAttachment0,2 1 sheets which includes TUGC0 Engiieering authorization) i
)
, A-000181 pp A-49
Trip Report Page 5 Item 4.
A. The serial number for the 28 channel recorder was found scratched out and changed, therefore the calibration status for this equipment was suspect.
I Corrective Action: ANCO contacted the Rental Company (Genstar) for this equipment concerning the S/N discrepancy.
Genstar stated because the unit was purchased in a different year than it was manufactured, the S/N was changed to reflect that date. Genstar sent ANCO a written statement to this effect and a review of this written statement was perfomed by TUGC0 QA and found satisfactory.
B. No objective evidence from the Rental Co. or in ANCO's files to indicate the calibration status for the 28 channel recorder.
Corrective Action: ANCO comitted to perform the cali-bration at their facility. ANCO then developed Calibration Test Procedure No. A-000167, Rev. O, 3-20-86,to be used to
{ perform this calibration, which encompass the calibration requirements taken frcm the manufacture's manual for FM/DR g multi-channel type recorders. The procedures were reviewed 1
[ and approved by ANC0 management prior to use.
ANCO calibrated the 28 channel recorder using instruments traceable to NBS. The calibration activity was properly ,
documented by ANCO.
l The TUGC0 QA Representative witnessed and verified the calibration activity and the results were found to be satisfactory.
Item 5.
( A. Calibration of the Hewlett-Packard Plotter Recorder Model
- 7015B: No objective evidence was available to indicate calibration since 1984.
' ANCO does not have a procedure to cover the method of calibration for this instrument. l l
Corrective Action: Prior to TUGC0 identifying this noncon- ;
} fomance, ANCO had developed Calibration Procedure No. (
A-000152 to be used to calibrate the plotter recorder.

Calibration of this instrument was perfomed by ANC0 person- i nel during this visit and verified by TUGC0 QA Representa- j tive that the instruments used to perfom the calibrations j were traceable to NBS and properly documented on ANC0's t calibration record foms.
'l A review of the calibration records was perfomed and found satisfactory by TUGC0 QA.
Item 6.
A. No controls in place to cover calibration lab access to equipment / instruments and records.
Corrective Action: A continuing effort tiy ANCO is in process to up-date all calibration record and files. The Lab is beirig staffed from 8:00 a.m. to 6:00 p.m. Records are being kept on instruments being checked in and out to provide accountability and calibration status. The Lab is now fenced off with a locked area for calibrated instruments and a stringent control of access key availability has been improved. (See ANCO memorandum 3-19-86 Attachment P)
All of the above, was witnessed and verified by the TUGC0 QA.
Item 7.
A. The Resonant Frequencies procedure used during testing was
' not submitted and approved as required by Purchase Order CPF-12839-S.
Corrective Action: ANCO developed a procedure for identify-ing frequencies of interest in Random Test. A re-l1 view / acceptance with no further comments was perfomed by the TUGC0 Representative, Z.T. Shi, Ebasco. (See Attachment Q, 2 sheets)
Based en the verification and witnessing. activities per-formed by TUGC0 QA, and the positive response and imediate implementation of corrective action by ANCO Engineering, the TUGC0 QA Representative requested to remove the Stop Work Order 86-001.
On March 19, 1986, B.C. Scott Supervisor, Vendor Compliance issued the Start Work Authorization (see Attachment R) to lift the restriction and to allow ANC0 to continue the test j activities for TUGC0 work.

The Model PT-101 is a position or displacement transducer
) designed for measurements from 0-2 inches to 0-500 inches.
It provides an electrical signal proportional to the linear extension of a stainless steel cable. It can utilize either AC or DC as an excitation source and will provide a stepless output by means of a potentiometer with effectively infinite resolution. Non-linearity a
errors are less than 0.1% of full range. .
Displacement is measured by attaching the cable to the moving )
part and the body of the transducer to any fixed convenient surface. Retraction is effected by means of a constant tension !
j spring motor which maintains uniform tension on the cable. ;
~
Response acceleration rates to 100 G's may be provided.
{
A ruggedized version of the transducer designated Model
~._ _ ~- l j
PT-101RX is available for use in extreme environments. This instrument will endure shock of 2.000 G's for 6 milliseconds, and vibration of 50 G's over the 100-2,000 Hz spectrum without changes in calibration or damage.

- 3. Connect the blue and green leeds (DC-D) or pins A and D (HCD or HPD) to a DC readout device. Make certain that the blue lead or pin A, as applicable,is the signal connection.
- 4. Insert core into LVDT, making certain that the end. marked with a red dot is pointed away from the connector or lead end.
- 5. Apply input power.
- 6. Move the core of the LVDT to the position where the indicated output voltage roads zero. This is the null point of the LVDT and the point from which positive or negative full scale is measured. When the core is moved toward the lead (or pin) end. an increase in positive voltage is produced. Movement in the other direction causes a negative output. In these series of LVDT's, full displacement of tbc +: ore will cause an output of 10 volts + 5 percent.

Appendix D contains peak transducer data. The first part con-sists of data for Case 7,100% cable fill. There are results from l
four tests--tests going from the SSE seismic to the highest level fragility test. All the peak transducer data is presented. The next part of this appendix consists of Table D.1--a list of some peak accelerations for each test case, for OBE and SSE seismic behavior level input and 100% cable fill. Finally, a sample of the time histories for Cases 3 and 7 is presented.

ABSTRACT The incentive for this work was to help l determine if that vast majority of equipment in As seismic shake table testing equipment nuclear power plants was adequately tested when has evolved, we have been able to more placed on two-dimensional (rather than three-realistically simulate seismic inputs and more dimensional) tables.
reliably qualify equipment. Most qualification in the past 10 years has been perforued on Typical seismic testing procedures, independent tiaxial tables because 1) these were representing the " state-of-the-art" from the the best available and 2) it was felt that they early 1970 s to the present, involve independent provided a sufficiently valid test input. The biaxial tables (vertical plus horizontal) issue of the adequacy of a biarial test in capable of rendon (earthquake-like) input. The simulating a triazial event was a mute point missing third direction (normally the second until independent triaxial tables became horizontal) has been accounted for in two ways.

First, the required response spectra froe both horizontal directions are enveloped, and the Recent exploratory , studies using ANCO's result set as the goal for the single table indapendent triarial table to simulate both horizontal direction. Second, the equipment is triaxial and biazial inputs have shown that, for tested at two orthogonal directions (i.e.,
two classes of equipment, the standard biarial rotated 90 degrees between tests) so as to testing procedure produces an adequate expose all the equipment's axis to input (conservative) test when compared to actual (although not simultaneously). Such testing is triaxial events. (The two classes of equipment made further conservative by two other factors.

The project also revealed (typically by 215%). This greatly increases significant statistical variation in fragility their energy content. Second, floor motions are p between tests of " identical" components.) These most often predicted as time histories.

The lab desirable, there is reason to belisve that past must now find a time history that matches this biarial tests are probably adequate. Based on (highly artificial) spectra and generally these initial studies, certain recommendations results in a much more severe earthquake than are made for a detailed exploration of this the originally calculated floor motion.

SUMMARY
The major finding of this program is that for the equipment tested, broadened and enveloped biaxial tests are as severe or more severe than realistic triaxial events. (This is illustrated in, for example, Figure 2,) We did find significant (factor of 2) variations in fragility between " identical" components and 1- about 20% to 30% variation on test repeat. e number of other factors affect fragility i (rotation, up- and down-shift of spectra, no broadening of biarial inputs) but appeared to be of secondary importance.
