You have been tasked with designing a one-story barn. The mean roof height is 25 ft, and the roof angle is 20 degrees. The basic wind speed has been provided by the local building authority and is 110 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 eight conditions listed in ASCE 7-10 section 28.6.2. Determine the adjustment factor for building height and exposure, λ, for the Main Wind Force Resisting System using the Simplified Envelope Procedure.
