Page 2 of 4 EECE#: EDM 06-34 Helleran 8712 200'h St. SW STRUCTURAL COMMENTS General 1. Please resubmit an analysis for the lu for the cantilever beams. The lu is not continuously supported since the compression face is not the top lam but on the bottom due to cantilevered conditions. Also, the worst case scenario is not adding the full load over the beam but the code requires the live to be applied on alternate spans to produce the maximum stresses in the member. Resubmit an analysis with the proper unsupported length used and alternative live loading as required per code or clearly point out where this was done to meet the code. IBC NDS table 3.3.3 and IBC 1607.10 2. The design analysis for the studs to use as a column clearly state the wood plate shall have a F'c perpendicular to grain a minimum of 724 psi. The wood member used for this house will exceed this. For HF the F'c is 405 and for DF the F'c is 626. Please modify accordingly. NDS table 4A. 3. Please note on the drawing that the wood plate under the 4X6 columns shall be Doug fir species as required per analysis. HF will not support the design loads. NDS tablet Sheet A-6 FOUNDATION PLAN: 4. The design analysis required the garage shear wall to be the raised shear wall to meet the height to width ratio with shear wall mark SW4 nailing requirements. Please note detail 4 on shebt Al shall be used at these locations as required by the Engineer of Record's (EOR) design. 5. EOR, please specify the required reinforcement for the 24X24X8" concrete footing or provide calculations to justify it is not required. Sheet A-7 UPPER FLOOR/LOWER ROF FRAMING PLAN: 6. EOR, please modify note 3 of the shear wall schedule. The code requires 3X members, not double 2X, unless double the amount of anchor bolts are provided than required per analysis. Please modify as required. IBC 23 053.10 7. EOR, please modify note 7 to state single 3x member and not (2) 2x. The code specifically states a single 3X nominal member shall be used. IBC 2306.4.1 footnote i. S. EOR, please specify the required connection of the 3-1/2 PSL to the supporting 3- 1/2 PSL. The drawings state flush framing so a hanger is required to support this beam and should be specified on the drawings. IBC 2304.9.6 Page 3 of 4 EECE#: EDM 06-34 Helleran 8712 200"' St. SW 9. EOR, please specify on the drawing the required post to beam connection for the 3- 1/2 PSL. The detail added to the drawings on sheet A10 is for 5-114 beam. The code requires to clearly specify the post to beam connections. IBC 2304.9.7 10. EOR, please specify the required post to beam connection for the beam number 6, beam number 10, etc... There are other locations so please add the required post to beam connections as required per code to the drawings. IBC 2304.9.6 11. EOR, please specify the size of the wood beam located over the kitchen window. 12. EOR, please specify the required connections of the 6X8 headers over the porch. 13. EOR, please provide detail for the support at the intersection of beam mark 12 and mark 7. 14. EOR, please provide detail for the connection of the beam number 5 to beam number 13. 15. The analysis states the shear wall at the garage shall be a raised shear wall but the drawings state SW4. EOR, please verify drawing call out as compared to the analysis. 16. Please provide a detail on the drawing for the deck framing. By definition the deck would classified as a balcony and is required to be designed for a force of 60 PSF. Also, the guard rail shall be designed for a 200 pound force applied in any directions. Please submit details and analysis for the balcony. IBC table 1607.1 and IBC 1607.7.1 17. Please submit an analysis for the 117/8 TJ1210 at the balcony, bonus room and bedroom number 2. The analysis submitted does not match the framing. The joist is a two span with cantilever at each end. Also, the analysis submitted for this member states uplift exceeds 200 pounds and a detail must be added to resist this force. Please modify accordingly. 18. The compression flange TJI at the balcony and bonus room must be braced at 4' 2" spacing per the analysis. Gypsum wall board will provide adequate bracing for the compression flange but the drawings should clearly specify the required attachments as required to prevent buckling.. Please add blocking members or specify the required attachment of the gypsum wall board to the bottom flange. I also called Truss Joist and their engineer also states this is very important and should be clearly defined on the drawings. TJI truss design manual requirements. Sheet A-8 UPPER ROOF FRAMING PLAN AND DETAILS: Page 4 of 4 EECE#: EDM 06-34 Helleran 8712 200th St. SW 19. EOR, please specify the required connection of the wood post to the girder truss. The truss manufacturer typically does not specify this but leaves that up to the design professional. 20. Please modify note 3 of the shear wall schedule. The code requires 3X members not double 2X unless double the amount of anchor bolts are provide than required per analysis. Please modify as required. IBC 2305.3.10 21. Please modify note 7 to state single 3x member and not (2) 2x. The code specifically states a single 3 X nominal member shall be used. IBC 2306.4.1 footnote i. 22. Please specify the required post to column connections on the drawings. This shall include the case where double studs are used as columns. This should be clearly shown on the drawings to assure the complete load path to the foundations. Sheet A-9 BUILDING SECTION AND DETAILS: 23. Retaining Wall detail: Please submit an analysis for the retaining wall detail shown. Also, the drawings do not specify the required footing depth for the retaining wall. Please add this information to the drawing with supporting analysis. IBC 1806 Sheet A-10 WINDOW SCHEDULE AND DETIAI.S: 24, Detail 8: The code requires having the vertical bars have the standard 90 degree hook in the footing in design category D. Please note this on the detail. 25. Detail 11: The code requires the vertical bars to have a standard 90 degree hook in the footing unless an analysis is submitted to develop the bar. Please note this on the drawings. 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, 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
