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 a partially-enclosed building. The mean roof height is 20 ft, and the roof angle is 5 degrees. The basic wind speed provided by the local building authority is 140 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 2E using the positive value of GCpi for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.
