The following roofing materials are stacked on a pallet at a construction site. The pallet is 4 ft by 4 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.5 layers of fiberboard, 1/2-in.6 layers of decking, 2-in. wood (Douglas fir)5 layers of plywood, 3/8-in. thick

You have been tasked with designing a one-story building as a sewage treatment plant. 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 120 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 eight conditions listed in ASCE 7-10 section 28.6.2. Determine the simplified design wind pressure, ps30, on Zone F of the Main Wind Force Resisting System using the Simplified Envelope Procedure.
