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 open building. The mean roof height is 15 ft, and the roof angle is 30 degrees. The basic wind speed provided by the local building authority is 120 mph. Assume that exposure category B is applicable and that the building is not located on a hill or an escarpment. Determine the velocity pressure, qh.
