The two columns in the following floor framing plan support only loads from a gymnasium on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 12.5 psf acts on the tributary area of the columns. Combine this with the reduced floor live load, and then determine the total load that acts on one of the columns.

You have been tasked with designing a one-story building as a sewage treatment plant. The mean roof height is 25 ft, the roof angle is 10 degrees, and the effective wind area is 100 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.

The two columns in the following floor framing plan support only loads from a gymnasium on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 11.4 psf acts on the tributary area of the columns. Combine this with the reduced floor live load, and then determine the total load that acts on one of the columns.

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
