A steel member is labeled as a W18x50. The 50 indicates the _______ of the member.

For ASD, the safety factor for fracture is smaller than the safety factor for yielding.

A 3/4 in. x 5.0 in. plate is connected to a gusset with three 1/2 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A572 Grade 60: Fy = 60 ksi, Fu = 75 ksi. Assume that Ae = An. Compute the design strength for LRFD.

A 0.67 in. x 12.0 in. plate is connected to a gusset with eight 3/4 in. bolts. Standard sizing is used for the bolt holes. What is the net area of the plate?

Which is larger—the net area or the gross area of a tension member with bolt holes?

A 5/8 in. x 5.0 in. plate is connected to a gusset with three 1/2 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM 1066 Grade 50: Fy = 50 ksi, Fu = 65 ksi. Assume that Ae = An. Compute the allowable strength for ASD.

ASD stands for _______.

What is a legal document containing requirements related to such things as structural safety, fire safety, plumbing, ventilation, and accessibility?

Web members of a truss will either be in _______ or ________, depending on their location and orientation and on the location of the loads.
