The built-up girder below is comprised of four A572 Grade 50 plates welded together. Compute the section
modulus (S), plastic modulus (Z₁), and shape factor (Z₁/S). Using Table B41.b of the Specification,
determine whether the flanges and web are compact, noncompact, or slender.

A. A truss member is made with a pair of 4"x 3" x 3/8"
angles with the long legs back to back. The angles are 36 ksi
steel and are attached at the connection by a 3/8 in. plate
running between the angles. The unbraced length is 12 feet
and consider both ends fixed. What is the allowable axial
load in compression? In tension? How does the compression
capacity change if I connect them with a %" plate in
between? Does it change tension capacity?

C. A 28 foot column is braced top and bottom about the X-X
axis and has K bracing as shown on the Y-Y axis only. It is
built of A36 steel and is a W12 x 30 section. Can it support
an axial load of 165 kips? State its actual capacity.
Determine the nominal flexural strength of the following welded shape: The flanges are 3 inches x 22 inches, the web is 1⁄2 inch x 70 inches, and the member is simply supported, uniformly loaded, and has continuous lateral support. A572 Grade 50 steel is used.
