Yоu hаve been tаsked with designing а оne-stоry building as a water treatment plant. The mean roof height is 20 ft, the roof angle is 20 degrees, and the effective wind area is 50 square feet. The basic wind speed has been provided by the local building authority and is 115 mph. Assume that exposure category C 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 adjustment factor for building height and exposure, λ, for the Components and Cladding using the Simplified Envelope Procedure.
