Question
S 18.7 Two C10 x 20s are bolted to a gusset plate by four rows of 7/8-in.-diameter bolts as shown. The channels are made of A36 steel. Determine their tensile capacity if the type and total number of bolts are as follows: A325-F, N = 12. a. b. A325-N, N = 12. Note: Because the load is transmitted by bolts through only part of the channel (web) and there are at least three bolts in the direction of stress, the net area is only 85 percent effec- tive (AISC Specifications). e f a 1-1/2 in.- т 7/8-in. gusset plate 1-1/2 in. n@2-1/4 in. n 2-1/4 in.
