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...

Problem 6 A 24-ft long steel column has an S 8 x 23 section, with the cross-sectional properties: 1. = 64.7 in", I, = 4.27 in", and A = 6.76 in”, that is built-in at both ends. The midpoint of the column is braced by two cables that prevent displacement in the c direction. For a factor of safety against buckling of X = 2.5, determine the largest compressive axial load, Pmax. Use the material properties E = 29. 103...

2) The beam shown is supported by steel member BC as shown. Due to the forked ends on the member, consider the supports at B and C to act as pins for x-x axis buckling and as fixed supports for y-y axis buckling. Member BC is made of A992 steel with a modulus of elasticity of 29,000 ksi and a yield strength of 50 ksi. a) Calculate the maximum allowable load, P, on the system (in kips) considering buckling and...

A long, slender structural steel LE - 29,000 ksil H558 x4x 1/4 shape (see Appendix B for its cross-sectional properties) is used as aL-41.00-ft-long column. The column is supported in the x direction at base A and pinned at ends A and C against translation in the y and z directions. Lateral support is provided to the column so that deflection in the x-2 plane is restrained at mid-height B; however, the column is free to deflect in the x-y...
