You have been tasked with designing a one-story police station. The mean roof height is 20 ft, the roof angle is 20 degrees, and the effective wind area is 20 square feet. The basic wind speed has been provided by the local building authority and is 110 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 positive net design wind pressure for h = 30 ft, pnet30, on Zone 3 of the Components and Cladding using the Simplified Envelope Procedure.

You have been tasked with designing fire station. According to ASCE 7-10, what is the risk category for this building? Note that specific examples for each category are listed in the ASCE 7 commentary at the end of the document.

You have been tasked with designing a one-story barn. The mean roof height is 25 ft, and the roof angle is 15 degrees. The basic wind speed has been provided by the local building authority and is 120 mph. Assume that exposure category D 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 A of the Main Wind Force Resisting System using the Simplified Envelope Procedure.

The two columns in the following floor framing plan support only loads from a dance hall on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 12.8 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.

Determine the rain load, R, on a flat roof given the following data.Vertical distance from primary roof drain to scupper inlet, ds = 5.0 in.Vertical distance to top of rain water above scupper inlet, dh = 3.4 in.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 11.38 psf acts on the tributary area of one of the 50-ft girders, determine the equivalent distributed load that acts on the girder.
