Find the reduced roof live load for a one-story building which has columns evenly spaced every 30 feet in the north-south direction and 18 feet in the east-west direction. The building has an ordinary pitched roof with a slope of 2 inch/foot.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 12.11 psf acts on the tributary area of one of the columns, determine the equivalent point load that acts on the column.

You have been tasked with designing a one-story theater. The mean roof height is 25 ft, the roof angle is 15 degrees, and the effective wind area is 20 square feet. 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 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 4 of the Components and Cladding using the Simplified Envelope Procedure.

If a building contains columns that are evenly spaced every 17 feet in the north-south direction and 30 feet in the east-west direction, the tributary area of a typical exterior column would be _______.

If a building contains columns that are evenly spaced every 29 feet in the north-south direction and 14 feet in the east-west direction, the tributary area of a typical exterior column would be _______.

A 13-ft-long, simply-supported beam supports a concentrated dead load of 240 lb at its center. Determine the maximum bending moment in the beam.

A 15-ft-long, simply-supported beam supports a concentrated dead load of 400 lb at its center. Determine the maximum bending moment in the beam.

A dead load of 14.9 psf acts on a roof with a 7/12 inch/inch pitch. Determine the equivalent flat-roof load.

You have been tasked with designing a one-story theater. The mean roof height is 20 ft, the roof angle is 10 degrees, and the effective wind area is 20 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.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 7.78 psf acts on the tributary area of one of the purlins, determine the equivalent distributed load that acts on the purlin.
