A two-story building has the following characteristics. Determine the design earthquake spectral response acceleration parameter at short period, SDS, using ASCE 7-10.Risk Category IIISite Class BSS = 0.50, S1 = 0.20

Use the MWFRS Envelope Procedure in ASCE 7-10 Chapter 28, Part 1 to answer this question. Assume that the building meets the conditions described therein. You have been tasked with designing an enclosed building. The mean roof height is 25 ft, and the roof angle is 30 degrees. The basic wind speed provided by the local building authority is 125 mph. Assume that exposure category D is applicable and that the building is not located on a hill or an escarpment. Determine the MWFRS design wind pressure, p, on Zone 3E using the negative value of GCpi for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.

Use the Simplified Alternative Procedure in ASCE 7-10 Chapter 12, Section 12.14 to answer this question. Assume that the building meets the limitations described therein. A two-story building with the following characteristics has a bearing wall system consisting of special reinforced concrete shear walls. A certain shear wall in the building is 80 feet long by 18 feet tall and weighs 100 psf. Determine the seismic base shear, V, for the wall.Risk Category IISite Class CSS = 1.25, S1 = 0.75
