MONTFLY STATUS REPORT NUMBERIl PERIOD MARCH I,1984 TFROUGH MARCH 31,1984
- i.0 INTRODUCTION AND PURPOSE Monthly Status Reports have been instituted by agreement between the Consumers Power Company (CPC), the Nuclear Regulatory Commission (NRC) and TERA to provide parties external to TERA's IDCV project team with up-to-date information relative to program progress and any important issues identi-fied during the reporting period. This report covers the period from March I, 1984 through March 31,1984. A description of the scope, reporting periods and report issuance dates for Monthly Status Reports, as well as a summary of the background of the IDCV program were presented in the initial Monthly Status Report dated May 27,1983.
2.0 IDCV PROGRAM STATUS
SUMMARY
2.1 Programmatic Activities Attachment I provides an updated chronology of major project milestones. The project chronology from inception through the beginning of this reporting period con be found in the previous monthly status reports. Several milestones warrant special highlight.
On February 10,1984, TERA issued a letter that summarizes plans for comple-tion of the Midland IDCVP. A meeting was held on March 13,1984 at NRC's Bethesda, Maryland offices to discuss details of the plans. A summary'of this -
meeting was issued on March 15,1984. TERA indicated that the fundamental objectives and philosophy of the program have and will continue to remain intact; however, details of execution and timing have been refined to better deal with the status and recent programmatic evolutions of the Midland project. The -
NRC plans to issue a letter confirming their understanding and concurrence.

, .s The eighth OCR Status Review Meeting was held on March 28,1984 at Bechtel's Ann Arbor, Michigan offices. The schedule for Bechtel's response with odditional information relevant to outstanding civil / structural OCRs/ Findings was dis-cussed. it is apparent that delays in this creo of design verification will occur.
The full schedule impact will be quantified in early May upon receipt of j additional information from Bechtel and in consideration of issues discussed at on April 17,1984 meeting which will be held to assess the potential applicability of the SMA Seismic Margins Evaluation to the disposition of outstanding civil / structural OCRs.
l.
2.2 Design Verification Activities 2.2.1 Summary As discussed in Section 2.1, o major activity for March was the public meeting held at the NRC's Bethesda, Maryland offices to discuss plans for completion of the Midland IDCVP. Activities discussed at that meeting have been placed on hold pending a formal response to the plan outlined by TERA. It is expected that these activities will recommence in April after receipt of NRC comments and development of appropriate procedures. Work continued on the AFW System Performance Requirements topical report which has been on hold since November. Work was initiated on the CR-HVAC System Performance Require-ments topical report during March. Other activities during the month included dispositioning of OCRs and completion of previously initiated work.
2.2.2 Auxiliary Feedwater System Progress Work continued on completion of a topical report covering AFW System .
Performance Requirements topics. Additional information was received aliowing dispositioning of OCRs. Changes to OCR status are discussed in Section 3.0 of this status report.
In the civil / structural review area, progress was~ mode in dispositioning of OCRs.
i Meetings on OCRs, which discussed civil / structural items, were held on March l l
and March 28. At the- March 28 meeting, Bechtel reviewed their expected l

l response dates for providing information relevant to the outstanding items. The j scheduled response dates span the period late April through early May. TERA l anticipates IDVP delays as a direct impact of this schedule. TERA personnel were in Ann Arbor during the weeks of March 19 and March 26 to obtain odditional documentation and review Bechtel calculation files.
2.2.3 SEP System Progress Dispositioning of OCRs continued in March with information received to respond to the potential load discrepancies noted in OCR-3201-008-C-110 on a point-by-point basis. Additionally, pneumatic system leak-rate data were received as was a new diesel generator exhaust backpressure calculation. Responses to addi-tional OCR items, which were received at the March 28 OCR status meeting, are being reviewed. At that time TERA also received a copy of electrical calculation OPE-23 (0) on Class IE battery continuous load capability. OCRs which were resolved or otherwise dispositioned are discussed in Section 3.0 of this report.
Internal review of draft engineering evaluations is continuing, seven engineering evaluations and the diesel generator load tabulation calculation have been verified and are awaiting final approval. Draft engineering evaluations of the diesel generator and power distribution system electrical chorocteristics and protective devices / settings review topics are nearing completion. The technical review of the 120 Voc and 125 Vdc power systems is continuing based upon a previous receipt for requested additional documentation and calculation OPE-23 (O). .
2.2.4 Control Room HVAC System Progress l
Engineering evaluations for the major System Performance Requirements topics excluding Component Functional Requirements have been completed and are now in the verification process. The Component Functional Requirements engineer-ing evaluation was on hold pending completion of confirmatory calculations associated with revised cooling coil performance requirements. That effort will
- be completed offer revised flow diagrams con be reviewed to check consistency of flow rate used in the calculations.

l Two OCRs are yet to be resolved. OCR 3201-008-C-085 addresses the methods ;
for controlling calculations. A review of calculation control procedures has been I initiated, and followup octivities defined. OCR-3201-008-0-145 has been mode a l Confirmed item requiring a response from the project.
In March the review of fire protection issues unique to the CR-HVAC was initiated. Key issues have been defined and the P&lD and HVAC layout drawings have received a preliminary review to examine fire area boundaries. The status of the structural review of the auxiliary building which houses HVAC components is discussed in Section 2.2.2 of this report.
2.3 Construction Verification Activities ICV reviewers focused their activitics upon the disposition of existing Confirmed items and Findings and initiated the review of the Quality Verification Program (OVP) by reviewing the OVP Plan and supporting procedures. Pr:ncipal activities undertaken by ICV reviewers during this reporting period are as follows:
e Based upon formal responses received from Bechtel and CPC, ICV reviewers dispositioned the following Confirmed items and Findings.
Copies of these reports are included in Attachment 3 of this report.
Confirmed Previous Current item /Findino Status Status F-091: Lesson Plan for the Finding Resolved Hanger Reinspection Program C-092: Qualification of OCEs Confirmed item Resolved for the Conduct of Hanger.

e s e ICV program management participated in the_ March 13,1984 meeting held in the NRC's Bethesda, Maryland offices which was held to discuss plans to complete the IDCVP and to respond to questions from interested and concerned parties. ICV program management provided near and long-term plans for executing the ICV program methodology in accordance with the IDCVP Engineering Program Plon, as supple-
- mented with a review of Quality Verification Program (OVP). A summary of issues discussed and addressed during the meeting including the influence of the status of the CPC Construction l Completim Program (CCP) was provided in TERA letter of '
March 15,1984.
i e ICV reviewers commenced their review of the Quality Verification Program (OVP) by developing a detailed understanding of the OVP's charter and the significent controlling procedures. The emphasis of
, this review activity is to develop on understanding of important elements of the OVP to the extent that these elements have o bearing on the quality of end products as ultimately substantiated by the Quality Verification Packages generated by the OVP.
Near term octivities will include interviews with cognizant site
! personnel and observations of site 'OVP octivities to address the following:
~
Measures undertaken which guarantee the integrity ond completeness of quality verification packages; Methods employed which effectively integrate OVP
- outputs with outputs from the Status Assessment
, teams such that a clear and concise representation l of the quality of installed items is obtained and
, retained.
e Near term activities involve the continuation of the OVP review and a review and evoluotion of information received which should enable ICV reviewers to disposition Finding F-047 concerning site storage and maintenance activities.

SUMMARY
OF CONFIRMED AND RESOLVED ITEM REPORTS, FINDINGS
( REPORTS, AND FINDING RESOLUTION REPORTS Attachment 2 provides TERA's Trocking System Summary for Open, Confirmed, and Resolved (OCR) Item Reports, Finding Reports, and Finding Resolution Reports. This tool assists TERA in tracking the disposition of issues as they progress through the review process. Items that have changed status or that have been added during the reporting period are noted with an osterisk.
Attachment 3 provides retyped copies of current period Resolved item Reports (that have closed out Confirmed items), Confirmed items, Finding Reports, and Finding Resolution Reports. Several Observations are also attoched. The 2 following paragraphs discuss items which have changed status in the post month.
During March, a new Finding and eight new Confirmed items were identified. A previous Finding, one previous Open item, and six previous Confirmed items were resolved. Additionally, one Observation and three Open items were identified.
Accordingly, the status of disposition of OCRs/ Findings for the IDCVP from inception through April 17,1984 can be summarized as shown on Attachme'nt 4.
i Finding F-093 is concerned with deviations from AWS welding standards which were allowed in Project Spec. 7220-M-151 A, Rev. IS, without sufficient engi-neering justification. This may result in the acceptance of welds which are not
, in compliance with applicable codes and standards and which have not been j evaluated from o design standpoint.
Finding Resolution Report Z-091 provides close-out for an item concerned with the omission of training instructions for the inspection of snubber assemblies.in Lesson Plan Rev. 4 for POCl-P-2.30, Rev. 3. Documentation was provided by CPC that verified that the trainees did, in fact, receive' instructions for inspecting snobber assemblies. The documentation indicated that the course-instructor noted the omission prior to the training sessions and provided the required training for Lesson Plan Revs. 3 and 4. All other Lesson Plan revisions !
were found to contain the pertinent training instructions.
Confirmed item C-14S is concerned with inconsistencies noted in the CR-HVAC duct layout and systern configuration when the- physical arrangement ' drawing was compared to the P&lD.

Confirmed item C-161 identifies a situation where the voltage dror at the terminals of motor operated valves con exceed that required for operation.
Confirmed item C-162 is concerned with a lack of design criteria to address how motors which require 80% nominal voltage at their terminals to accelerate will be assured sufficient starting voltage when the electrical system design is such that the total voltage drop is less than 30%
Confirmed item C-163 is concerned with conflicting information presented in the FSAR regarding which version of IEEE 387 is Intended to govern the design of the diesel generators.
Confirmed item C-165 identifies a conflict between B&W NSB bus voltage requirements and calculated bus voltages available.
Confirmed item C-168 is concerned with contradictory statements in calculation 21G (4.154XQ) Rev. O, regarding the longitudinal support given by a support member.
Confirmed item C-169 is concerned with the impact of modal mismatch and corrected seismic analyses producing potentially larger accelerations than the ones documented in Spec. G-7.
Confirmed item C-170 identifies discrepancies in calculation 29D.268(Q) Rev. O, regarding the CR-HVAC system duct supports. Discrepancies in procedures, section length, modeling, and the moment distribution calculation are noted.

DESCRIPTION OF CONCERN:
The original confinned item was specifically related to apparent discrepancies in AFW parameters. Although the specific concerns (0CRs C-017, -018 -020
-027, and -028) were subsequently dispositioned, the finding and the finding i resolution reports (3201-008-F-018, Z-018) state that TERA will use the CR-HVAC and SEP systems as an additional sample to detennine the accuracy of the FSAR as a statement of design criteria.
This confinned item was not dispositioned pending further reviews. It is being i
revised now to consolidate and document the concerns which have developed which are related to the original confinned item. These concerns are: '
o The accuracy of the FSAR as a statement of design criteria o The extent to which the B&W BOP criteria documents and the actual plant design criteria are consistent and the methods used to resolve the discrepancies o Analyses to support some FSAR statements could not be located o FSAR updating process may not be consistent and timely.

Consumers Power Co. (CPC0) by letter serial 28589 dated 3-6-84 provided additional information which resolved this Item (022) and responded to TERA's letter from H. Levin to L. Gibson dated 2-14-84. The Confirmed Item is resolved on the basis that preoperational, hot functional and startup tests will, in a progressive manner, test the AFW S/G 1evel control systems. These tests will impose disturbances on and exercise the AFW S/G 1evel control system under conditions which simulate the expected plant operating conditions. System parameters will be monitored during these tests to verify stable system performance to design requirements. This testing is a reasonable alternative I to the above referenced B&W 1etter.

AFW Pump Turbine Minimum Flow Valve DCV PROGRAM AREA OR TASK (IF APPLICABLE): ;
Topic I.15-1, Control / Power Supplies DESCRIPTION OF CONCERN.
Under condition of loss of all AC (station blackout), the AFW pump minimum flow valve 2SV-3969B would not be operable because it is powered from Class lE AC power.
The Midland FSAR and B&W B0P criteria document (36-1004477) both require that AFW be operable for two hours under station blackout. During this period of time, flow through the minimum flow line may be necessary to prevent damage to the pump.
SIONIFICANCE OF CONCERN:
Failure to provide minimum flow would cause consequential damage to the AFW turbine driven pump during station blackout.
RECOMMEtOATION OR RESOLUTION X :
Documentation provided by the vendor indicates that the pump can tolerate a flow of 100 gpm for two hours. Calculations by TERA indicate that the post-blackout decay heat level will generally require more than 100 gpm. Conditions which would result in less than a 100 gpm demand are unlikely. The flow requirement during the first approximately 45 mins. of the event (assuming starting at full power) is governed by the level control system at about 200 gpm. Thus, sufficient time is available for the operator to diagnose the situation and operate the pump manually or take other appropriate action. Therefore, it can be concluded that the present design is adequatl .

Pipe Support DESCRIPTION OF FitOING (OR REFERENCE DOC. NO. OF FifOlNG REPORT):
As part of the review of the pipe support re-inspection program, ICV reviewers noted that Lesson Plan Rev. 4 for PQCI-P-2.30, Rev. 3 omitted Activity 3.4, instructions for snubber assemblies.
. . DESCRIPTION OF RESOLUTION:
The resolution was focused upon verifying that, even though the Lesson Plan omitted instructions for snubber assemblies, the trainees did in fact receive instructions for inspecting snubber assemblies. ICV reviewers received assurance from CPC in the form of memos initiated by cognizant and responsible MPQAD/ Training personnel which stated explicitly that even though the formal, approved Lesson Plan did not include instructions addressing Activity 3.4 of PQCI P-2.30, the course instructor noted the omission prior to the training sessions and provided the required training. This course of action was followed for Lesson Plan Revs. 3 & 4. All other Lesson Plan Revs.
(0,1, lA, 2, & 5) were reviewed and found to contain the pertinent training instructior s.

Pipe Supports - Topic 1.3-1c, Review of Selected Verif. Act. (0verinspection Programs)
DESCRIPTION OF CONCERN:
Within the hanger over-inspection program, QCE's who are being qualified are first given a listing of pipe supports that are available for inspection. The qualifying QCE is then afforded the opportunity to select the support which he/she finds through observation to be accessible, lighted, clean and with unpainted welds. These acti-vities are undertaken prior to conducting the " Performance Demonstration" portion of the " Capability Demonstration" to Instruction 7220/P-2.30, Reinspection of Pipe (Component) Supports.
slGNIFICANCE OF CONCERN:
The selection of the pipe support for the " Performance Demonstration" by the qualifying quality control examiner may introduce a bias in the " capability demonstration" by .
potentially allowing a qualifying QCE to select a hanger or support with which he/she is most familiar.
i RECOMMENDATION OR RESOLUTION X :
The resolution of this confinned item is based upon information presented to ICV reviewers by CPC which addresses the significance of concern and the recommendation presented in C-092 specifically:
(1) As of 10/15/83, Level III's designate which hanger /s a qualifying QCE will use for his/her performance demonstration as opposed to allowing the qualifying QCE to select the hanger /s.
(2) During the period when the practice was used which allowed the (See Attachment)

Deviations from welding standards AWS D9.1-80 and D1.1-79 noted in Project Specification 7220-M-151A, Rev. 15, (detailed in OCR 3201-008-C-093),were allowed without sufficient engineering justification.
SIGNIFICANCE OF FINDING:
The specification of limits on the acceptability of welds which are not in direct compliance with pertinent codes and standards may result in the acceptance of weldments which are not in compliance with' applicable codes & standards and which have not been evaluated from a design standpoint.
RECOMMENDATION:
Based upon CPC responses, TERA was provided assurance that appropriate actions had been initiated to reconcile items noted by TERA in OCR 3201-008-C-093. These actions were initiated prior to TERA's review. These actions confirmed the inconsistencies noted in Confirmed Item C-093. The intent of this Tinding is to retain the noted inconsistencies as Findings pending resolution of CPC Audit Finding Report MSA-83.-3-06F. As part of the actions undertaken by CPC to resolve AFR MSA-83-3-06F, an engineering evaluation is currently being conducted to address the acceptability of deviations from established welding codes & standards.

DESCRIPTION OF CONCERN:
I Based upon the results of the construction / installation documentation review, ICV
- reviewers statused selected components and comodities within the CR HVAC system j sample boundaries as " complete" or " incomplete" depending upon information recorded
~
on available quality verification documentation. Of forty-two (42) items initially selected for review, seven (7) items were statused as complete and therefore eligi-ble for a physical verification review. Upon conducting a physical verification of the seven (7) items, the following inconsistencies were noted. (See attached page.)
SIGNIFICANCE OF CONCERN:
An inconsistency noted in the Description of Concern may be classified as either a
~
defect or as an example of poor workmanship. The net effect is a situation wherein the structural integrity of the weldment or flange connection is placed into question.
RECOMMENDATION OR RESOLUTION Y :
Based upon CPC response to items noted in the Description of Concern, this item is considered resolved. ,
Item 1: At time of TERA inspection, this component had been/was in the process of being destatused as cart of CR HVAC weld testing program.
Item 2: This weld Subsequently brushed to bare metal by CPC and reinspected by two inspectors. No lack of fusion was found. Additionally,'" waviness" in duct work deemed acceptable within criteria guidelines. (See attached page.)
COMMENTS BY SRT (IF REQUIRED):
Ensure that CR HVAC sample be expanded to replace the items previously inspected and noted in this OCR.

- 2) Stiffener in mid-section of duct #50, " east" side of bottom capturing member, has a continuous weld for the 40" width of the duct (opposite side is " stitch" welded). The 40" weld has distorted the bottom plane of the duct and there are Indications of lack of fusion along the 40" weldment.
The " north" vertical flange, first and fifth bolts from the bottom do not have washers; second, third, and fourth bolts from the bottom have bent washers preventing full contact of the washer; bottom flange has two loose nuts.
" west" vertical flange has four loose nuts and the threaded end of bottom bolt is in contact with a vertical member of a support; top flange has one loose nut.
Resolution (Continued):
Items #3 & #4: Per the Inspection Plan, these components are considered part of the dampers, not the duct work. Since.the dampers had not been completed nor prepared for final inspection, TERA's findings were premature.

IDCV PROGRAM AREA OR Task (IF APPLICABLE):
Construction / Installation Documentation Review, Topic IV.2-3c.
DESCRIPTION OF CONCERN:
During the process of conducting a review of CR HVAC welding documentation to verify utilization of correct welding procedures as performed by qualified welders, the following was noted: there appears to be no means available for an inspector to verify that a welder was qualified at the time he welded on a specific fabricated duct or support in the CR HVAC system. This statement is made based upon a review of the applicable records, a cursory review of processes in place at the time welding was performed and discussions with congnizant personnel. The following understandings are noted: (See attached sheet.)
SIGNIFICANCE OF CONCERN:
Since no in-process weld inspection is performed, there is no check on the contractor properly performing to his procedure and maintaining the welder qualification records.
According to AWS D1.1-79 and AWS D1.3-78, the welder's qualification remains in effect indefinitely unless the welder is not engaged in a given process of welding 4
for which he is qualified, for a period exceeding six months. Since no dates are recorded, and the general WPS is the only weld callout, the proof of qualification maintenance required by AWS D1.1-79 and AWS D1.3-78 does not exist and cannot be genera .e d .
RECOMMENDATION OR RESOLUTION A :
Based upon CPC response contained in CPC letter Schaeffer/ Wood to Poser dated 2/3/84, ICV reviewers have resolved this confirmed item. Resolution is based upon the following:
- 1. A method is available to MPQAD to indirectly verify the status of a welder's qualification at the time a specific welder performed a specific weld. However, the i method is not foolproof and may not provide unequivocal evidence of a welder's qualifi- '
cation status at the time a weld was performed for 100% of the welds. (Seeattachedshnet.

, 1. The Zack Foreman does not document the date or the piecemarks of the hanger or duct assembly that a particular welder has fabricated. ItIf..possible for the requirements of three codes and many welding procedurasi,to be employed, it is the responsibility of the Zack Foreman to assure that the welder is qualified at the time of welding for the particular joint to be
- welded. .
- 2. The MPQAD inspector logs the welder and procedure used from information given to him by the Zack Foreman.
3 The Inspection by MPQAD occurs after all welding is completed. There may be a considerable lag time between completion of welding and final Inspection.
- 4. Prior to the latest system of three digit welding procedure specification ,
(WPS) numbers, the WPS was general in nature and did not designate a unique
" code-process-base material-Joint configuration" combination.
5 Quality verification records only Indicate which WPS was applied to the weldment, which welder (s) performed welding on the item and the date(s) of inspection. The records do not Indicate the date(s) of welding nor the PQR's used. Based upon available and recorded data it is difficult to discern how an inspector can verify a welder's qualification since neither the date of welding nor the specific PQR is recorded.
!( '
Resolution (Continued) l
- 2. CPC has modified the recording requirements during welding by requiring that all welds be traceable to a specific welder and date of welding.
These data were not previously recorded.
- 3. Two new welder surveillance programs have been implemented by Zack & CPC to scrutinize more closely the welder's qualifications and his actual )
performance during in-process welding activities. l Upon recommencement of the Construction / Installation Documentation review, l

5 DESCRIPTION OF CONCERN
! HVAC duct layout and system configuration were reviewed by comparing the physical
{ arrangement on Ref. I, Revision 22 to the P&lD (Ref.2), Revision 9. That review indicated a number of areas of inconsistency.
i i The following differences were noted:
! 1. Radiation Monitoring elements ORE 6513B and ORE 6514B are physically located
, downstream of the Makeup Air Filter by-pass branch and the P&lD shows them upstream of the branch.
- 2. OAE 6515B and OAE 6516B are physically located upstream of isolation valve OMO 6501. They are not shown on the P&lD.
- 3. OAE 6512B and OAE 65228 are located in close proximity along the same duct; the !
P&lD shows OAE 6521B upstream of OAE 6522B and the layout is physically the opposite. The layout also labels these devices as switches (OASH), not elements (OAE), whereas the P&lD shows the switch and the element as separate devices.
- 4. OFE 6520B1 is not shown in the layout drawing. The P&lD locates the flow element 1
i upstream of the Makeup Filter Unit.
- 5. The ductwork identification system used on the P&lD incorporates a size corres- '
ponding to the equivalent round duct diameter. Comparing a small number of specified equivalent diameters to the equivalent diameter calculated using the size shown on the layout drawing, there appear to be minor differences. All the duct is j slightly smaller than the P&lD calls for, and in one case a 10% difference was noted.
, out drawing stated, "This dwg was last checked against Rev. 4 of P&lD
- Note M-465 SH 9 of I onthe 1 lay /15/82." Revision 5 of the P&lD had already been issued a

(1/19/81). Revision 22 of Reference I was issued on 9/23/83 indicating it had been last .
checked against a P&lD which was now 32 months out of date. Based on the results of the 1
initial review a second review was performed against Rev. 4 of the P&lD to correspond to ;
the drawing check which was performed on 1/15/82, according to the drawing note. l
- Revision 11 of Reference I was used since it was the current Revision on 1/15/82. The :
drawings were found to be inconsistent in the areas noted above at the time that they 4

4 SIGNIFICANCE OF CONCERN: ,
The function of instruments can be critically influenced by location. For example, in item I above, the instrument elements are located in a dead leg of piping when the by-pass line isolation valve (OXV 6511B or OXV 65128) is closed. Detection of radiation level in the incoming flow could be inadequate and control room isolation would be offected. The issue raised in item 5 is not likely to have any technical consequence, because pressure drop in the duct is calculated using actual duct sizes, not P&lD equivalents, but inconsistencies in the documentation do exist. Collectively, the observed inconsistencies may indicate inadequate control of the desigri drawings which utilize the P&lD as input.

However, FSAR Section 8.1.4.3 discusses conformance to IEEE 387-1977 and does not mention IEEE 387-1972 in that discussion. However, in the lead-in paragraph on page 8.1-4 (Rev. 49) 387-1972 is mentioned. Also, FSAR Appendix 3A Reg. Guide 1.9 addresses compliance as relating to IEE 387-1977. It is not clear which version of IEEE 387 really applies.

In the referenced calculation, sh 8 states: (1) "The bottom of duct is welded to support member 4" and (2) " detail 10/C-885 gives no longitudinal support."
Considering that the mentioned member 4 is welded to a massive steel column, the second statement seems incorrect.
I' SIGNIFICANCE OF CONCERN:
In the evaluation of the support mentioned, longitudinal support force has been neglected because of an erroneous assumption. Support member 4 and its welds have been evaluated neglecting the longitudinal support forces. If errors of this nature occur systerratically, they may have significant cumulative effect.

Incorrect orocedures have been used in calculating xA at pt. 4. For < - '
example, wwn forces as shown in the sketch en sh 5 act on mm.Mr 1-4,e contrary to what is shown in the calculation,.no rotation of this member i V occurs as the resultant forces load the memb6r only axially.- 1herefore, displacement of members 1-4 and 3-6 is not compatible at pt. 4. ~
~
- 2. Sh 5: ,
In calculating vertical displacement at pt. 4 the length'of ser.' tion- ' -
4-6 is taken as 60 inches, whereas the sketch on sh 2-shows this length /
to be 72 inches. ,
- 3. Sh 8: - - -
In analyzing the member spanning from pt. 3 to pt. 6, improper mo/il~is used for the member. Calculation as performed assumes a pinned support - '
at pt. 3 in x-direction, whereas a spring representing the flexibility of member 2-3 should be modeled at pt. 3. ,. J ,- -
- 4. Sh 9:
~
The moment distribution calculation for member 3-6 using Cross's Pethod is erroneously performed. (The model of the member for which t>e calcula- -
tion is performed is itself erroneous, as indicated in item 3 'above.)
Member 3-6 is assumed to be pinned at point 3; however, in the course of calculation moment is " carried over" to this point. '
