li'age 22. Page 38 of the structural calculations appears to provide line loads for earthquake loading at "Level 2 of 3". See IBC Sections 1604.1, 1604.4, and 1613.1. The following additional information shall be submitted for review: Specify the procedure being used for the design (i.e., Equivalent Lateral Force or Modal). See ASCE 7-10 Sections 12.8 and 12.9. Note that the following comments presume the ELFP has been used. If the modal procedure has been used, provide documentation substantiating the lateral forces as required by Section 12.9. Response; The Seismic procedure used was per ASCE 7-10 Equivalent Lateral Force Procedure Lize Provide calculations substantiating the seismic weight tributary to each level. Response; The requested detailed calculations are attached per your request. Please see Woodworks tabulations printout on pages 20-23 and detailed load tabulations. ,Provide calculations substantiating the vertical distribution of the seismic base shear to each diaphragm level including the roof. Response; The requested detailed calculations are attached per your request Please see Woodworks tabulations printout on pages 20-23 and detailed load tabulations. 0.4-ie Foundation and Main Level floor framing plans on Sheets S-3.0 and S-4.0, respectively, and Section 7/S4.1, indicate shear walls occur at the first story on Grid B. The shear walls are not specified on the plans. Response; The detail under question was erroneous and has been corrected The plans appear to have a discrepancy on the presence of a wall at Grid B/3. The drawings should be reviewed and revised as needed. See IBC Sections 107.2.1 and 1603.1. Response; The requested drafting correction has been made for the redundant column G[ 44LRY (1 .4.-1- 6'Get'•®•gi ow 4'LEI 0. he design includes wood portal frames at the first story on Grid A.5 per Sheet S-4.0. Apr Calculations substantiating the design of the portal frames shall be submitted for review. Note that the design does not qualify for use of the prescriptive design procedures of the IRC or IBC Section 2308 per Table 2308.2.1. The calculations shall substantiating the capacity of the design to resist the governing design lateral forces per ASCE 7-10. At the EOR's option, a proprietary system may use in the design; an ESR shall be submitted to substantiate the design. The documentation shall establish the response modification factor appropriate to the system per Section 12.2.1; the most stringent value shall be used for the entire building per Section 12.2.3.1. See IBC Sections 1604.1, 1604.4, 1609.1, and 1613.1.
