Determine the nominal shear strength of a W16x36 of A572 Grade 60 steel.

Determine the magnitude of the largest shear force (consider both positive and negative peaks). Use a = 23 ft, b = 8 ft, and w = 6 kips/ft. The reaction forces for this beam are Ay = 60.65 kips and By = 125.35 kips.

Determine the limiting laterally unbraced length for the limit state of yielding, Lp, for a W16x36 with a simple span of 28 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 40 ksi.

Using ASD, determine the nominal flexural strength of a W18x46 beam made from A992 steel that has lateral support at 2-ft intervals. Assume Cb = 1.0.

Determine the limiting laterally unbraced length for the limit state of yielding, Lp, for a W16x36 with a simple span of 12 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 60 ksi.

Determine the nominal flexural strength, Mn, of a W8x31 for a simple span of 20 ft with continuous lateral support. Use Fy = 75 ksi and Cb = 1.0.

The policy of “containment” can best be described as

Determine the limiting laterally unbraced length for the limit state of inelastic lateral-torsional buckling, Lr, for a W16x36 with a simple span of 22 ft if lateral bracing for the compression flanges is provided at the ends only. Use Fy = 45 ksi.
