You have been tasked with designing a one-story fire station. The mean roof height is 20 ft, the roof angle is 15 degrees, and the effective wind area is 50 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 positive net design wind pressure for h = 30 ft, pnet30, on Zone 3 of the Components and Cladding using the Simplified Envelope Procedure.

A cardboard box that has been glued to the ground experiences pressures p1 = 0.25 psi and p2 = 1.05 psi on one side. The box has dimensions L1 = 18 in., L2 = 8 in., and h = 13 in. Use the pressure tributary to the diaphragm (lid) of the box to determine the reaction force V2 between the diaphragm and the shearwall (short side of the box).

The following roofing materials are stacked on a pallet at a construction site. The pallet is 4 ft by 7 ft, and the materials have been cut and stacked so that each layer completely covers the pallet. Use ASCE 7-10 to determine the total dead load resting on the pallet.4 layers of fiberboard, 1/2-in.7 layers of decking, 2-in. wood (Douglas fir)7 layers of plywood, 5/8-in. thick
