Problem 4: An HSS 254x152.4x 12.7 structural steel column (see Appendix B for its cross-sectional properties) is 9m long, and its ends are pinned. Its Young's modulus E-200 GPa, and its failure stress is 250 MPa. A factor of safety of 1.82 is specified for its use. a) Considering only buckling, determine the maximum compressive stress that the column can support. Considering material failure, determine the maximum compressive stress that the column can support. b) c)...

Problem 2. Design and select an ASTM A992 (Fy" 50 ksi) W-shape column to carry an axial dead load of 140 kips and live lond of 420 kips. The column is 30 feet long, and is pinned top and bottom in both axes. In addition, the column is laterally braced about the y-y axis (local weak/minor axis of the section) and torsionally braced at the midpoint. Limit the column size to a nominal 14 in. shape, that is W14 shape...
