You have been tasked with designing a one-story building as a sewage treatment plant. The mean roof height is 25 ft, the roof angle is 20 degrees, and the effective wind area is 20 square feet. The basic wind speed has been provided by the local building authority and is 120 mph. Assume that exposure category B is applicable and that the building is not located on a hill or an escarpment. Also assume that the building is an enclosed simple diaphragm and that the building meets all five conditions listed in ASCE 7-10 section 30.5.1. Determine the negative net design wind pressure for h = 30 ft, pnet30, on Zone 2 of the Components and Cladding using the Simplified Envelope Procedure.
