Use the AWC Special Design Provisions for Wind and Seismic, 2015 Edition and ASD procedures to answer the following question.A building with a non-structural interior wall is exposed to a transverse load of w = 350 lb/ft. The roof is sheathed with double-layer diagonal lumber sheathing. Is the diaphragm satisfactory in regard to the maximum diaphragm aspect ratio? Let L = 36 ft, a = 30 ft, b = 6 ft, be = 20 ft, and bi = 7 ft.
