Determine the nominal block shear strength of a L8 x 8 x 9/16 consisting of A36 steel that is attached through one leg to a gusset plate with two 7/8-inch-diameter bolts. Assume a = 4 in., b = 2 in., and c = 6.25 in.

Determine the shear lag factor U for a 3/8 x 6 consisting of A36 steel with a transverse weld to its flange only.

Determine the net area for an L8 x 6 x 1/2 with two lines of 7/8-inch-diameter bolts in the long leg and one line of 7/8-inch-diameter bolts in the short leg. The bolts are not staggered.

Determine the net area for a C9 x 20 with four lines of 7/8-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.

Determine the shear lag factor U for a C12 x 30 consisting of A36 steel with two longitudinal heel welds of length L = 6 in.

Determine the shear lag factor U for a C8 x 11.5 consisting of A36 steel with two longitudinal heel welds of length L = 6 in.

Using the Steel Construction Manual, A992 steel is preferred for which structural shape?

When calculating U = 1 – x/L for a connection with a single row of bolts, the L is measured from the center of one bolt to the center of the next bolt.

Undesirable vibrations can occur in tension members that are excessively slender.
