The tension member shown in Figure is an L6 × 3 ½× 5/16. The bolts are ¾ inch
ameter. If A36 steel is used, is the member adequate for a total load of 100 kips?
The shape shown in Figure is a W18 x71 with holes in each flange for 1-inch-diameter bolts. The steel is A992. Compute the nominal flexural strength for an unbraced length of 10 feet. Use Cb =1.0.
A double-angle shape, 2L7x4x3/8, is used as a tension member. The two angles are connected to a gusset plate with 7/8-inch-diameter bolts through the 7-inch legs, as shown in the figure 3. A572 Grade 50 steel is used. Compute the design strength and the allowable strength.
