Problem 5: A double-angle tension member, 2L 76 × 51 × 6.4 LLBB (Longer legs are connected back to back), of 436 steel is subjected to a dead load of R/15 kN and a live load of R/6 kN. It is connected to a gusset plate with 20mm diameter bolts through the long legs. Does this member have enough strength using LRFD method? Assume that A. = 0.854µ. Section Figure. Problem 5
