Assuming that the basic design snow load is not specified by the local building official, determine the total design dead load plus snow load for the rafters in the building illustrated. The building is a standard residential occupancy located near Houghton, Michigan in Exposure C terrain, with trees providing shelter on all sides of the structure. The building is heated, the rafters are sloped at 6 in./ft, and the roof covering consists of cement asbestos shingles. Determine the shear and moment for the rafters under dead plus snow loads if they are spaced 4 ft-0 in. o.c. Roof dead load D has been estimated as 14 psf along the roof surface.
