An L6×6×1/2 is used as a tension member, with one gage line of 3/4-in Ø bolts in each leg at the usual gage location (see Table 3.1).What is the minimum amount of stagger, s, necessary so that only one bolt need be subtracted from the gross area of the angle? Compute the net area of this member if the lines of holes are staggered at 3 in. (Ans. s = 4.77 in, An = 5.05 in²)
