3-D RESPONSE SPECTRUM ANALYSIS STUDY I. INTRODUCTION The cable tray hangers are classified as Seismic Category I structure, and they are design verified for the effect of dynamic load induced by the postulated seismic event combined with the applicable concurrent loading. The above design requirement is delineated in CPSES, FSAR and NRC standard review plan. There are, in general, four (4) acceptable analytical approaches to consider the seismic load in designing of the Seismic Category I structure, which are:

1) Static analysis (SA) method using 1.5 times the peak spectral' value as an input requirement per Reg Guide 1.100 recommendation.
2) Equivalent static analysis (ESA) method using an amplification f actor to multiply the spectral "g" value corresponding to the lowest system frequency, and accounting thus for multimode responses.

This approach has been used in seismic design of cable tray hanger system for many nuclear power plants such as Grand Gulf, Hope Creek, Seabrook, South Texas, Susquehanna, Limerick and Palo Verde. These are the plants we know of and we believe other plants have used this methodology.

3) Response spectrum analysis (RSA) method using spectrum curves as an input requirement 1
4) Time history analysis (THA) method using earthquake time history as an input requirement.

Each of these analytical approaches has its own merits. The cable tray hangers of the Comanche Peak Unit No. 2 project are in general design verified by employing the equivalent static analysis method, and it is planned to also use this method for the design verification of the Unit 1 CTH's. An amplification f actor of 1.25 is used to account for the multiple modal responses during the occurrence of the seismic event. This amplification f actor is referred to as the "Multimode Response Multiplier" (MRM), and is used to multiply the g value corresponding to the lowest frequency of the system, in each of the three orthogonal directions. The purpose of response spectrum and time history analyses of this study is to demonstrate that the amplification f actor (MRM) of 1.25 is adequate to cover the multiple modes and system effect on the total seismic response of all cable tray hanger system in both units, when used in conjunction with the response (acceleration) determined by ESA for the lowest frequency in each direction. The Multimode Response Multiplier is calculated by the following formula: MRM = IL-8f where - = the weighted average "g" value obtained from the g response spectrum analysis results at all points of the 3-D model which represents the multi-span cable tray hanger system. 2

gf = the "g" value corresponding to the conservatively calculated system fundamental frequency, which combines the hanger frequency and cable tray frequency using Dunkerley formula. The cable tray hanger, which was considered in Dunkerly formula, was also used in 3-D t model. The following sections describe how the cable tray hanger runs were selected to represent the actual systems, the modelling assumptions, analysis approach, seismic input requirements and summary results. II. THE SELECTION OF 3-D STUDY MODELS The MRM study deals with a small number of cases. These cases where selected so that all reasonable ranges of frequency encountered in the plant are accounted for. In this respect three cases .were studied. Two idealized cases were "made-up" to cover the low and high ranges of frequency. Furthermore, an actual case was studied to account for variability of hangers geometry and stiffness as well as variability of cable tray spans and size, accounting thus for the system effect. To account for the variability of input the maximum (top floor) response spectra of four building were used for the study as well as the response

 - spectra of the elevation where the supports studied are located.

When the 3-dimensional finite element models of cable tray runs are constructed we closely simulate the dynamic behavior of the actual installed 3

cable tray hanger system, using the same modelling techniques used for equivalent static analysis _ of cable tray hanger design verification program. The seismic respouse of the cable tray hanger system depends on the rigidity of the system (reflected in the dynamic characteristics of the system, which in turn, are measured by the range of frequencies inherited from its structural and mass configuration, etc.), and on the characteristics of the input motion. The main purpose of the study is to obtain the seismic response range which can represent the actual installed configurations of the cable tray hanger system, and demonstrate that a Multimode Response Multiplier established as 1.25 in each direction is applicable for the seismic design verification of all cable tray hanger systems installed for Comanche Peak project. The refore , the aforementioned parameters, i.e., the frequency of the system and the type of seismic input motion, are considered as basic criteria on selecting the proper cable tray hanger runs analyzed and the adequate seismic input motion as an input. In order to cover the possible fundamental frequencies range of the as-built cable tray hanger system, three (3) different 3-D models were assembled with the following characteristics:

1. Model No.1 (Made-up toward rigid range of the spectrum)

This 3-D model consists of four (4) maximum cable tray spans (8'-0) and five (5) trapeze hangers, of which four are identical transverse type r 4

and one is a longitudinal type hanger. Both the longitudinal and transversal type are actuals and selected to provide the lowest frequencies, as close as possible to the peak. Three (3) layers of cable trays (12"x4") without thermolag are located on three horizontal tiers. The fundamental frequencies and higher frequencies in three (3) orthogonal directions of this "made-up" model are located on the right side of the spectral peak, and are intentionally chosen to maximize the MRM as explained in Section g (P.8).

2. Model No. 2 (Made-up toward flexible range of the spectrum)

The run configuration of this model is similar to Model No.1 with the following exception: Three (3) trays without thermolag are mounted on two horizontal tiers with two 12"x4" trays on the lower tier and one 24"x4" tray on the upper tier. This model provides a first frequency to the lef t of response spectrum peak. The fundamental system frequency in vertical direction is located on the lef t side of the spectral peak, while the other two fundamental system frequencies are located on the right side of the spectral peak. The structural and load characteristics of the installed system is such that it is rather unlikely to find systems with the transversal and 5

longitudinal frequency to the lef t of spectral peaks. The higher modes can be either totally to the left or at the peak or to the right of the response spectra depending on the location of the floor response spectrum (see Section g).

3. ~ Model No. 3 (Actual Installed Run)

This 3-D model represents an actual as-installed cable tray hanger run located at EL 852.5' of Safeguard Building. The tray run consists of five (5) unequal spans and six (6) tray hangers, four of which are non identical trapeze types, one is a horizontal cantilever, and one is a SP-7 with brace longitudinal type hanger. There are two layers of 24"x4" trays mounted on two separate horizontal tiers with 4 and 5 inch offset from the center of tiers. The two trays are fire protected by The rmolag. The longitudinal fundamental system frequency is located on the lef t side of the spectral peak, and the other two are on the right side of the spectral peak. Higher mode frequencies range on all sides of the spectral peak depending on the particular location of the floor response spectrum, ie, building, elevation etc. The characteristics and/or the variability of design parameters covered bf these three (3) different models can be briefly summarized as follows: 6

m-

a. Types of tray hansers Trapeze, cantilever and SP-7 type hangers are represented in the 3-D
                                                   ~

models. Among these, some are transverse types and some are longitudinal type hangers.

b. Type of cable trays 12"x4" and 24"x4" trays are included in the 3-D models. These two sizes of trays are the most frequent types of trays installed at site.
c. Span Lengths A maximum, equal span length of 8'-0 (Models No.1 and No. 2) and actually installed unequal span length varying from 6'-0 to 7'-0 (Model No. 3) are considered in the 3-D models.
d. Number of tray layers Multiple layers of three identical tray runs and two layers of different sizes of tray run are included in 3-D models. This creates many close modes in the vicinity of the fundamental mode and this is desirable to maximize the MRM.
e. The rmolas The effect of Thermolag was included in Model No. 3.

f. Frequency Ranae of Models As pointed out previously, the f undamental f requencies of these 3-D models are located in the three regions of the predominant spectrum curves, i.e., they f all into flexible, amplified and rigid modes response regions. The magnitudes of frequencies in three orthogonal directions of the studied cases coser the full range of spectrum frequencies and are listed in Tables A and B.
g. Relationship Between Modal Response Distribution and Spectrum Input Shape The magnitude of the seismic response MRM for a given tray hanger system depends on the relative location of all major important modes with respect to the amplified response region of the spectrum curve. In order to explain and or appreciate the above important relationship between modal response and spectrum curve input, the frequencies (Table A) of these three (3) models were plotted on a set of response spectrum curves, which were used as the seismic input in this study.

(see Section IV-5). The two examples of Section IV-5 illustrate that modal frequency distribution vis-a-vis response curve shape is such as to maximize MRM value. In short, the three (3) different 3-D models, which included the above various design parameters can represent and simulate conservatively the dynamic behavior of the as-installed cable tray hanger systems for Comanche Peak Project application. 8

III. STUDY CONCLUSION The Multimode Response Multipliers obtained from this study are as listed in the Tables I and II and exhibit the following isportant properties:

1) Most of the MRM are less than 1.0, and only 5% of them are greater than 1.0, with the largest value being 1.18 for the vertical direction, for model 3.
2) The variation of MRM for various buildings and different floor elevations is not, for most cases, significant.
3) The magnitudes of HRM is not influenced by the response spectrum differences of OBE and SSE events.
4) The MRM of 1.25 includes the effect of baseplate flexibility. All models of ESA approach do not account for the baseplate (base angle) flexibility when calculating the frequency. In verifying tim responses by using the 3-D models both flexible base and fix base cases were considered. Therefore tim 1.25 MRM can be used conservatively with ESA approach when calculating the system frequency with fixed bases.
5) The magnitudes of MRM depend on the relative closeness of the system fundamental frequencies with respect to the spectral peak, and the number of higher modes located within tie amplified region. In general a fundamental frequency to the lef t of the peak gives a higher value MRM than the one on the right of tim peak.

11

6) The MRM obtained using the enveloped horizontal response spectrum curves (NS and EW) as a seismic input requirement are conservative, because the spectral peak frequency range for enveloped curves is broader than that for individual spectrum curve. Thus artificially more higher modes were located within the amplified region.
7) Additional conservatism inherent to the application of equivalent static analysis approach. This study demonstrates that a MRM value of 1.25 is conservative when used with the Equivalent Static Analysis (ESA) approach. The ESA has in addition conservatism built-in by the usage of simplified formulas and approaches. These conservatisms are worthy to be noted, as follows:

a) Single cable tray frequency calculation is made by assuming full design load (in Unit 2) and simple supported end conditions. Both conditions result in the lowest fundamental frequency for the cable tray. b) Multiple cable tray frequency value is assumed to be the same and equal to the lowest tray frequency of the set. Tids artificially lowers the frequency for some trays and assumes that all trays vibrates in phase and transmit at all times maximum load on the hanger. 12

c) Dunkerley's formula which combines tray f requency with hanger frequency always give the lowest frequency value for the system. When support mass versus tray mass or the stiffness ratio are very large the Dunkerley's formula gives very conservative (very low f requency) values, and results in large "g" increases. d) The shift in frequency due to base flexibility was studied and found insignificant in increse of the "g" values.

== Conclusion:==

As stated in item 1, 95 percent of MRM are less than 1.0. Furthe rmo re , accounting for the conservatism associated with the enveloped horizontal response spectrum curves (ites 6), the use of 1.25 MRM in conjunction with equivalent static analysis

  • results in a comfortable safety margin in the seismic design verification of tim cable tray hanger systems installed at Comanche Peak plant.
  • And "g" calculated at tre f undamental f requency in each of the three orthogonal directions.

IV. STUDY

SUMMARY

1.0 Modelling Assumption

1) The cable tray hangers selected for the 3-D models are represented by finite beam elements, which simulate the stiffness ,

characteristics of both cable tray hanger and cable tray itself. The section properties (area and moment of inertia) of the tray section were extracted from the static load test included by cable tray vendor in their seismic report of cable tray. The cable loading is simulted by concentrated masses lumped at each of the five nodal points along the cable tray span between hangers.

2) The connections between cable tray and horizontal tiers simulate the mechanism of transferring tray loading to support member for the [

transverse type and the longitudinal type clamps accordingly.

3) The longitudinal type hangers have the espability to resist three orthogonal directions of the earthquake components, while the transverse type hangers resist one vertical and one transverse (normal to tray run) earthquake components in addition to being subjected to the self-weight it.duced seismic inertia force in longitudinal direction. The modelling technique simulates this dynamic response behavior for different type of hangers accordingly.

1 14

4) The boundary conditions simulate the actual installed conditions, either by moment connection or hinged connection, and the 3-D models with these types of boundary conditions are referred to as " fixed base" models. In addition, the flexibility of the base angle and/or base plate is included in the modelling, and such 3-D models are referred to as " flexible base" models.
5) All offsets resulting from member assemblage (working points for

, braces, load of cg) are not considered in the 3-D models. The effect of these offsets on the system frequency is insignificant, therefore the effect of offsets on the overall seismic response (acceleration) can be excluded form the modelling consideration. Ilowever, the offset between horizontal tier and tray has been considered and simulated in 3-D model, because it affects f requency. 2.0 Seismic Input Requirements A set of 4% damping OBE and 7% damping SSE floor response spectrum curves are used as an input for the 3-D response spectrum analysis. The floor response spectrum curves are selected f rom Reactor Internal, Reactor Auxiliary, Electrical and Safeguard Buildings. The 28 response spectrum curves included in tte study cover seven elevations of the four buildings, in both horizontal and vertical directions. 15

The floor response spectrum curves at the top elevation of each building and in addition, the response spectrum curves at the actual location of support are used in spectrum analysis. As mentioned in Section II, the magnitude of seismic response for a given structural system depends on the characteristic of seismic input motion, which is represented by a set of floor response spectrum curves, since the seismic input motions for subject analysis represent various buildings and various floor elevations, therefore, the amplification f actor established from the resonse results of 3-D modal analysis using various seismic motions as inputs can e used in static equivalent analysis of cable tray hanger for Comanche Peak Project. 3.0 Analysis Approach Multimode Response Multiplier is established by comparing the responses (accelerations) obtained by either a time history analysis or a spectrum response analysis with the responses (accelerations) used in the equivalent static analysis. A spectrum response analysis approach was used for Model 3 in accordance with tie requirements delineated in Reg.1.92 for the method of modal response superposition. A time history analysis approach was utilized for Models 1 and 2, both of which exhibited " unreasonable" (see footnote) cross coupling effects among the three directions when the spectrum response method recommended by Reg. 1.92 is used. Footnote: " Unreasonable" means that under a more accurate (time history) analysis these modes cannot possibly add up. 16

c . . This unreasonable cross coupling effects were eliminated when a sine-wave time history was used as an input for the dynamic analysis of 1 Model 1 and 2. The eartiquake time histories were not available at the time when the models 1 & 2 analyses were completed (and issued on Septembe r 19, 1985) To compensate for the unreasonable coupling, the spectrum response analyses were finished using the SRSS method for superposition of all modal responses. Time histories were made available to Ebasco by Gibbs and Hill on October 11, 1985, and a time history analysis was performed on Models 1 & 2 to reconfirm that the HRM's obtained from the previous response spectrum analyses are still conservative even though SRSS method for modal superposition was used. , The time history analyses results did confirm previous results and proves that the absolute sum for closely spaced modes should be used

 , with caution, and response of all modes which unreasonably couple should be combined by SRSS. The f requency range of 3-D models considered in the response spectral analysis is from 3.7 to 33 H,. The total modal mass corresponding to all modes response is checked to be 90% of the total mass. When it is not, the residual mass is multiplied by the largest spectral acceleration at or beyond the cut-off frequency and applied as a rigid body force on the system.

4.0 Study Results The analysis results obtained f rom the three (3) models indicate that

                                               ~

the MRH for each 3-D model and each direction is less than 1.25. Therefore, these response spectrum analysis results demonstrate that a

   ' MRM of 1.25 as specified in the seismic design criteria for cable tray hangers for Comanche Peak project is adequate to be used in the seismic design verification of the cable tray hangers, by the equivalent static analy ses.

The actual Multimode Response Multiplier for each of three (3) orthogonal directions are listed below for three (3) different models corresponding to both the fixed and the flexible base conditions (Tables I and II). In addition, the MRM established from time history and response spectral analyses for Models 1 and 2 were presented in Table III. 18

5.0 Discussions Further evaluation and discussions of some significant cases provide confirmation of the conclusions which were presented elsewhere in this study. The most significant cases are comparison of flexible vs amplified range (example 1) and rigid versus amplified range (example 2).

1. Example 1. Comparison of seismic response MRM of the flexible response region vs that of the amplified response region.

! The longitudinal fundamental frequencies of Model No. 3 are 4.3 !!z for a fixed boundary condition, and 3.7 !!z for a flexible boundary condition. They are both at lef t side of tim spectral peak curves at EL 852.5' (SSE peak at 5.5 liz to 8 liz) and EL 896.5' (SSE peak at 6.511: to 10 lis) of Safeguard Building.

I The above tabulation reconfirms the following intuitive features of MRM which ist a) The MRM of the seismic response of the cable tray hanger system with a fundamental system frequency located at the left of the peak tends to increse as the f undamental system f requency moves close to the peak 1.e., 0.466 vs 0.533, and 0.626 vs 0.643 provided an equal number of higher modes are located within the amplified region. This is why it is not necessary to construct systess the lowest frequency of which would be even futher lef t of the peak response than the one produced by the made-up models, le 3.7 Hz, since the made-up models have already provided a sufficient number of higher modes within the amplified reston.

2. Example 2. Comparison of the seismic response NRM of the amplified response region vs. that in the rigid response region.

For example, the vertical fundamental system frequency of rigid base Model No.1 is 9.8 Hz and that of rigid base Model No. 2 is 6.2 Hz. The seismic responses MRM of these two models for different buildings spectra are summarized below: 23

  • For model 2 eleven higher modes fall within the amplified region, while for model 1 only eight higher modes f all in tiw amplified region.

The above summary leads to the following observations a) The seismic response MRM of the tray hanger system with a vertical fundamental system frequency located in the amplified response region (or in the spectral peak range) is larger than tim case where fundamental system frequency is located in the relatively rigid response region (or for at right side of tim peak), ex. 0.89 of Model No. 2 vs. 0.63 of Model No.1 (both at EL 899.50', of Safeguard Building). b) The vertical fundamental f requency of Model No.1 is located on tim lef t of the amplified response region of spectrum curve at EL 896.50' of Saf eguard Building. Ilowever, it is at the right of tim amplified region of the spectrum curve at EL 899.50' of Reactor Auxiliary Building, and the seismic response MRM of same hanger system is larger when fundamental frequency f alls in the flexible range versus when f undamental f requency f alls in tim rigid range. 24

This example concludes that the magnitudes of seismic responses MRM totally depend on the relative closeness of the system fundamental f requency with respect to the location of spectral peak, the number of modes within the amplified region and the position of the lowest frequency in the flexible or rigid range regardless of hanger configurations and their mounting locations. From above two illustrated examples, the seismic response results demonstrate thats a) The dynamic characteristics (or f requency ranges) of three (3) 3-D models do represent most of the as-installed cable tray hanger system, because the system fundamental frequency varies f rom the flexible (at lef t side of peak) to amplified (on the peak), and rigid responne region (at right side of the spectral peak) for a given response spectrum curve. b) The magnitude of seismic response depends on the relative closeness of the system fundamental frequency with respect to tim location of spectral peak for a given spectrum curve. Since the system fundamental frequencies of three (3) 3-D models represent tim possible variation on frequency ranges of most as-installed cable tray hanger systems, and the response spectrum curves from different buildings and different floor elevations were used as seismic input requirements, i.e. the variation in seismic input characteristics was included in analysis. The re f ore , the range of seismic response obtained from these three (3) 3-D models can cover the seismic response of various installed cable tray hanger systems, and the enveloped amplification factor (MRM) established f rom 25

demonstrate that 1.25 amplification factor envelope the range of MRM derived from these three (3) 3-D model seismic response analysis, such that a validity of using 1.25 MRM is thus concluded. The following response spectrum graphs examplifies the relative postion of fundatmental and higher modes for various response spectrum curves. B" 26
