Members with compression and bending

Compression members are structural elements that carry compressive axial force. They are the vertical members of a building that support beams and their design, which is governed by buckling and strength. Columns are known as struct or compression members, which are subjected to compressive forces. These members provide stiffness to the building and avoid any imperfection regarding the transfer of axial load. For instance, webs in a truss, braces in a framed structure, tiers, and so on.

Question

A long, slender structural aluminum [E = 69 GPa] flanged shape is used as a l = 9.2-m-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-z plane is restrained at mid-height B; however, the column is free to deflect in the x-y
plane at B. Assume that b; = 102 mm, d = 122 mm, t; = 8 mm, and t, = 6 mm. Determine the maximum compressive load P the
column can support if a factor of safety of 2.9 is required. In your analysis, consider the possibility that buckling could occur
about either the strong axis (i.e., the z axis) or the weak axis (i.e., the y axis) of the aluminum column.
