The 13.25-m-long HSS 304.8 x 203.2 x 9.5 (see Appendix B for its cross-sectional properties) column shown is fixed at base A
with respect to bending about both the strong and weak axes of the HSS cross section. At upper end B, the column is restrained
against rotation and translation in the x-z plane (i.e., bending about the weak axis), and it is restrained against translation in the
x-y plane (i.e., free to rotate about the strong axis). Use the AISC equations to determine the allowable axial load Pallow that may
be supported by the column, on the basis of
(a) buckling in the x-y plane.
(b) buckling in the x-z plane.
Assume that E = 200 GPa and oy = 250 MPa.
