Design the tension members of roof truss shown in the figure. Use double-angle shapes throughout and assume 3/8-inch-thick gusset plates and welded connections. Assume a shear lag factor U = 0.85. The trusses are spaced at 25 feet. Use A572 Grade 50 steel and design for the following loads. Metal deck: 4 psf of roof surface Build-up roof: 12 psf of roof surface Purlins: 6 psf of roof surface (estimated) Snow: 18 psf of horizontal projection Truss weight: 5 psf of horizontal projection (estimated) a. Use LRFD.
