SITTS & HILL ENGINEERS, INC. <br /> the redundancy factor of 1.3 is more conservative than the amplified seismic load including the <br /> overstrength factor for cantilevered columns of 1.25 per ASCE Table 12.2-1. Per ASCE Section <br /> 12.4.3.2, the redundancy and overstrength factors are not applied at the same time. <br /> 13. Response: The design considers a redundancy factor of 1.3 per page 7 of the calculations. <br /> 14. Response: The axial load on the columns is less than 20% of the columns axial capacity, per <br /> ASCE 12.5.4, no seismic load interaction is required. <br /> 15. Response: No seismic load interaction is required per response to Structural Comment 14. The <br /> column is structurally adequate for the load combinations per ASCE Sections 12.4.2.2 and <br /> 12.4.3.2. The axial load in the column does not exceed 15% of the column axial capacity. Please <br /> see page 24 of the revised calculations for additional information. <br /> Please see the revised Drawings for additional information.
