Question

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 plane at B. Determine the maximum compressive load that the column can support if a factor of safety of 1.75 is required. In your analysis, consider the possibility that buckling could occur about either the strong axs·e the 2 axis or the weak axs·e, the y axs of the steel column. HSS8 x 4 x 14 LateralB bracing es kipS
