Use Fu=58 ksi and assume the edge distances are 2 and the distance center to center of holes is 3 inches. You may also assume that the deformation at the bolt holes is a design consideration and Pu = 345 k (LRFD) , Pa = 230 k (ASD).

The three pieces of steel are lapped by 7 inches and the bolts are to be spaced at 2 inches, 3 inches and 2 inches. The 2 exterior pieces of steel are ½ in PL while the middle piece of steel is ¾ inch PL.

The number of bolts is
