A tee shape made from A913 Grade 70 steel is fabricated from two plates of steel. The flange plate is 0.625 in. × 18 in., and the stem plate is 0.625 in. × 7 in. Determine whether the shape is compact, noncompact or slender.

An engineer analyzes an unbraced frame and determines the sum of the required load capacities for all the columns in the frame is 420 kips (unfactored) while the total elastic buckling strength of the same frame is 3,536 kips. From these values, what is the LRFD amplification factor for sidesway moments of the frame?

Determine the nominal flexural strength, Mn, of a W6x20 for a simple span of 18 ft with continuous lateral support. Use Fy = 75 ksi and Cb = 1.0.

A W14x82 of A992 steel is to be investigated for use as a beam-column in an unbraced frame. The length is 13 feet. First-order analyses of the frame were performed for both the sway and nonsway cases. The factored loads and moments corresponding to one of the load combinations to be investigated are given for this member in the following table. The multiplier to account for P-δ effects was determined to be 1.14, and the multiplier to account for P-Δ effects was determined to be 1.21. Determine the required second-order axial strength, Pr, of the member.Type of analysisPu (kip)Mtop (kip-ft)Mbottom (kip-ft)Nonsway3804516Sway12030100
