The above referenced project is in the process of plan review for compliance with Edmonds ordinances and applicable codes. The following comments, Page 2 of 4 deficiencies/corrections must be addressed prior to completion of plans review and subsequent issuance of permits. Provide revised plans and calculations along with a written response to each of the items listed below to facilitate a shorter back -check time. SCOPE OF REVIEW Tke scope of this review isfor the structural only requirements of this project. All features were checked only to the extent allowed by the submittals provided. All portions of this project are assumed to meet or will meet other departmental requirements, conditions and concerns before permit approval. Original comments will be written in italic if unable to confirm the items have been addressed/conected on the drawings. STRUCTURAL COMMENTS General 1. 3. The design analysis used states ha6(the base shear will go into the moment firames and the other half resisted by the wood shear wall. Submit an analysis that the wood shear wall will resist thisforce. The design analysis used an R factor of 6.5 not 3.5for ordinary steel momentframe. The code requires to use the least value ofR in the design. If using R of3.5 then ha4rgoes to each side and this is acceptable but not R of 6 5for the wood shear wall and R qf3.5for the moment frame. The code requires you to use the least R value at that level JBC 1614-62.2, The response states the other half goes into the concrete wall. This is fine with flexible diaphragm but the R value for concrete bearing wall is 4.5 and the R value for moment frame is 3.5. The R value used in the design of 6.5 is not correct for this structure. The reason for the different R value in the code is based off testing and different stiffness of vertical resisting elements. The stiffer elements will take more of the lateral force then a less stiff element. Resubmit analysis with the appropriate seismic R value at the appropriate level. 2. 5. This structure does notfall under the exceptionfor not having a quality assurance plan, Please add a quality assurance plan stamped and sign by the license design proftssional. IBC 1705 The response states not required for this structure but per code it is. This building does not fall under the exceptions and a quality assurance is required to be added to the documents. This is required to be stamped by a licensed professional in the state of Washington. IBC 1705 Sheet 7 FRAMING PLANS: Page 3 of 4 3. 13. Detail N Provide an analysisfor the attachment ofthe guard to the rim board to resist the 200 pound requiredforce applied in any direction. Also specify the required gage of the bolts on the drawings. IBC 1607.7. 1 Response states calculations have been provided but I was unable to find this in the submitted package. Please clarify where this information is located on the response. Also what is the spacing of the vertical post? This typically would be determined form the analysis and added to the drawings. Please supply this information and modify accordingly 4. 14. Detail J- Provide an analysisfor this detail as shown. Response states this to be a deferred submittal. The city will have to verify this as an acceptable response. 113C 1604.4 5. 15. Engineer oJ'Record (EOR), please provide positive connections oJ,the cantileverjoist and PSL to the wideflange beam. Details only show the attachment of the blocking. IBC 106 The drawings still have not been modified to show a positive connection to the members in order to transfer the code required forces. Please add this information to the drawing. 6. 17. Detail N7 and Detail K7. Please specify the required connection ofthe joist to the top plate. A positive connection is required at this location. IBC 106 1. 1 Detail K7 still does not specify the required connection. Please add this to the drawings and resubmit. 7. 18. Provide an analysis and detailfor the doublejoist supporting the (3) stringers. IBC 1604.4 1 was unable to find where this analysis was submitted in the response. Please clarify on the response where this analysis is done, 8. 19. Provide a detailfor the required connection ofthe glu-lam beam to the post. Nothing is specified at this time. IBC 106 LI I was unable to find where this was called out on the drawings. The response states it to be done but it is not clear what the required connections are at these locations. Sheet 8 FRAMING PLANS: 9- 22. Detail K.- The diameter of 'the WHS is required to be specified Thisisrequired to transfer the diaphragm shear and also this braces the compressionflanged of the wideflange. Please add this information to the drawings. IBC 106 The response states to use JB2210 hanger for the wide Range beam connection. Touse JB connector per Simpson catalog 16d must be used. This will not work for this connection. Please modify accordin ly. 9 Sheet S I DETAILS: Page 4 of 4 10. 29. Detail 2:Submit an analysis tojustify this connection convidering omega times the seismicforce. IBC 1605.4 The frame is required to be a moment frame in order to transfer the lateral loads. The connection must be checked per AISC 341 per IBC 2205.2.2. This has modified each code cycle since the Northridge earthquake. The connection was required to analysis to resist 3Rw/8 then it was modified to omega time the force. The connection is required to have an analysis submitted. Please submit this analysis. Additional corrections may be required following receipt of corrections and additional information as requested. Your plans are being reviewed concurrently with the Building Department, Fire Department, Zoning Department and Public Works Engineering. Changes, elp clarifications or additional corrections may be required subsequent to the Building Department plan review when comments are received from the other concerned departments. Should you have any inquiries regarding this letter, please contact Hoyt Jeter at (253) 857-4151 between 8:00 a.m. and 5:00 p.m. By: Hoyt Jeter, P.E. President
