Use the MWFRS Envelope Procedure in ASCE 7-10 Chapter 28, Part 1 to answer this question. Assume that the building meets the conditions described therein. You have been tasked with designing an enclosed building. The mean roof height is 25 ft, and the roof angle is 30 degrees. The basic wind speed provided by the local building authority is 125 mph. Assume that exposure category D is applicable and that the building is not located on a hill or an escarpment. Determine the MWFRS design wind pressure, p, on Zone 3E using the negative value of GCpi for Load Case A. Disregard the minimum pressure of 16 psf described in section 28.4.4.

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 13.0 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 police station. The mean roof height is 20 ft, the roof angle is 15 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 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 adjustment factor for building height and exposure, λ, for the Components and Cladding using the Simplified Envelope Procedure.

Use the MWFRS Envelope Procedure in ASCE 7-10 Chapter 28, Part 1 to answer this question. Assume that the building meets the conditions described therein. You have been tasked with designing an open building. The mean roof height is 25 ft, and the roof angle is 30 degrees. The basic wind speed provided by the local building authority is 150 mph. Assume that exposure category C is applicable and that the building is not located on a hill or an escarpment. Determine the external pressure coefficient GCpf on Zone 1E for Load Case A.

The City of Atlanta has adopted strict development guidelines with a focus on “being green.” As a result of the change, many new buildings must have a rooftop “rain garden” to reduce site rainfall runoff. The roof is flat. What should the roof live load be for an interior column with AT = 400 square feet?
