Unformatted text preview: standard holes, using a pitch, p = 3 in; end distance, L e = 1 ½ in; and side distance, L s = 1 ½ in. A992 (F y = 50 ksi, F u = 65 ksi) steel is used. L 4 x 3 ½ 1 3” Problem 2: Determine the design strength of the structural member consisting of a double-channel tension member and a plate with 20 in. width and 2 in. thickness. All three limit states in both the double-channel tension member and the gusset plate should be checked, and the smallest design strength from a total of six possible design strength values is the final answer. Figure 2 shows the structural member. LRFD and ASD are both used. 7/8 –in-diameter bolts in the standard holes, and A992 steel. C.G. of Channel Figure 1.
