A tension connection consists of A36 steel double angles (two L4x4x1/4 shapes, or 2L4x4x1/4)
fastened to a 4x10 No. 2 Red Oak member with a single row of four 0.875 inch A307 bolts.
The connection is subjected to normal temperatures but wet in-service conditions. Assume
the group action factor is C,=0.95 and the geometry factor is Ca=1. The controlling ASD
load combination is D+ L where L is from occupancy.
