A36 steel; 7/&in.-diameter A325N bolts

s = 1.50 in. L, = 1.5 in. g1 = 2.25 in. g, = 2.50 in. g = 2.50 in.

The tension member is a pair of L6 x 4 x 1/2withalllegsbolted to3/4in.-thicksplice plates. The bolt holes are shown on one angle with the short leg flattened down into the plane of the long leg. For the member, compute the design strength due to:

1. Yielding on A,

2. Fracture on A,

3. Block shear rupture

Is the design satisfactory for P, = 308 kips?
