Find the reduced roof live load for a one-story building which has columns evenly spaced every 15 feet in the north-south direction and 12 feet in the east-west direction. The building has an ordinary pitched roof with a slope of 8 inch/foot.

The density of a dried piece of 2×6 Aspen dimension lumber that is 20 feet long and has a moisture content of 9% is _______.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 11.03 psf acts on the tributary area of one of the columns, determine the equivalent point load that acts on the column.

Determine the flat roof snow load, pf, for a building kept just above freezing with a roof that is sheltered in terrain category D and has a risk category of II. Assume the ground snow load is 54 psf. Do not consider the minimum roof snow load, pm.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 8.68 psf acts on the tributary area of one of the sub-purlins, determine the equivalent point load that acts at the center of the sub-purlin.

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.

The following roofing materials are stacked on a pallet at a construction site. The pallet is 4 ft by 4 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.6 layers of deck, metal, 20 gage8 layers of plywood, 1/2-in. thick

The two columns in the following floor framing plan support only loads from a bowling alley on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 12.9 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 maximum actual deflection of the following beam. Assume normal temperatures, bending about the strong axis, and no incising. Ignore the weight of the beam.Load:wD = 100 lb/ftwLr = 450 lb/ftLoad combination:D + LrSpan:L = 11 ftMember size:4 x 12Stress grade and species:No. 2 Douglas Fir-LarchUnbraced length:lu = 0Moisture content:MC > 19 percentLive load deflection limit:Allow. Δ ≤ L/360

You have been tasked with designing a one-story fire station. 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 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 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.
