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.

You have been tasked with designing a one-story building as a sewage treatment plant. The mean roof height is 20 ft, and the roof angle is 20 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 adjustment factor for building height and exposure, λ, for the Main Wind Force Resisting System using the Simplified Envelope Procedure.

The density of a dried piece of 4×4 Southern Pine dimension lumber that is 8 feet long and has a moisture content of 9% is _______.

Determine the flat roof snow load, pf, for an unheated building with a roof that is fully exposed in terrain category B and has a risk category of IV. Assume the ground snow load is 33 psf. Do not consider the minimum roof snow load, pm.

You have been tasked with designing a one-story police station. The mean roof height is 25 ft, and the roof angle is 20 degrees. 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 eight conditions listed in ASCE 7-10 section 28.6.2. Determine the simplified design wind pressure, ps30, on Zone C of the Main Wind Force Resisting System using the Simplified Envelope Procedure.

Determine the rain load, R, on a flat roof given the following data.Vertical distance from primary roof drain to scupper inlet, ds = 4.9 in.Vertical distance to top of rain water above scupper inlet, dh = 2.7 in.

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.

The following roofing materials are stacked on a pallet at a construction site. The pallet is 3 ft by 6 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.9 layers of asphalt shingles7 layers of deck, metal, 18 gage6 layers of plywood, 3/8-in. thick

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 _______.

The following roof framing plan shows girders, purlins, and subpurlins. If a dead load of 7.90 psf acts on the tributary area of one of the sub-purlins, determine the equivalent distributed load that acts on the sub-purlin.
