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 20 ft, and the roof angle is 20 degrees. The basic wind speed provided by the local building authority is 140 mph. Assume that exposure category C is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure, qh.
