A double-angle tension member, 2L 3x2x 1/4, is subjected to a dead load of 12 kips, and a live load of 36 kips. It is connected to a gusset plate with one line of 3/4-inch-diameter bolts through the long legs. Is this member safe? Assume U=0.85. Fy =36 ksi and Fu = 58 ksi.
4) Find the most efficient (i.e., with the smallest weight per unit length) single angle tension member of A36 steel to resist the following service loads: dead load- 60 kips, live load 120 kips, and wind load = 50 kips. The member will be connected through one leg with 3/4-in diameter bolts in two lines and four or more bolts in each line (see figure below). Assume that the bolts are aligned and shear block failure is prevented. The member...
