In the gabled roof structure shown below, determine the sloped roof snow load Ps. The building is heated and is located in a windy area in Boston. Its roof consists of asphalt shingles. The building is used for a manufacturing facility, placing it in a type II occupancy category. Determine the roof slope factor, Cs using the ASCE graph shown below. If roof trusses are spaced at 16 ft on center, what is the uniform snow load along a truss?
