The Fu for A572 Grade 55 steel used in various structural shapes is _______.

Slenderness is the ratio of length to minimum _______.

Determine the nominal block shear strength of a L8 x 8 x 1/2 consisting of A36 steel that is attached through one leg to a gusset plate with two 3/4-inch-diameter bolts. Assume a = 3 in., b = 1.5 in., and c = 6.25 in.

If a tension connection is made with bolts, the reduction in cross-sectional area is _______ if the fasteners are arranged in a staggered pattern.

What is the maximum suggested slenderness ratio for tension members in the AISC specification?

Determine the net area for a C9 x 20 with five lines of 5/8-inch-diameter bolts. Each flange will contain one line of bolts, and the web will contain three lines of bolts. The bolts are not staggered.

Determine the nominal strength for the following PL 3/8 x 6 plate of A36 steel with two holes for 3/4-inch-diameter bolts. Assume a = 1.5 in., b = 3 in., and c = 1.5 in.

Determine the nominal strength for the following PL 1/2 x 10.5 plate of A36 steel with two holes for 3/4-inch-diameter bolts. Assume a = 3 in., b = 4.5 in., and c = 1.5 in.

Determine the shear lag factor U for a WT9 x 30 consisting of A992 steel with a transverse weld to its flange only.

Determine the net area for a C15 x 50 with four lines of 5/8-inch-diameter bolts. Each flange will contain one line of bolts, and the web will contain two lines of bolts. The bolts are not staggered.
