You have been tasked with designing a small, one-story healthcare facility. The mean roof height is 25 ft, the roof angle is 15 degrees, and the effective wind area is 10 square feet. 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 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 restaurant on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 11.1 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 emergency communications center. The mean roof height is 15 ft, and the roof angle is 20 degrees. The basic wind speed has been provided by the local building authority and is 115 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 adjustment factor for building height and exposure, λ, for the Main Wind Force Resisting System using the Simplified Envelope Procedure.
