Chapter 11, Problem 11.9.4P

Select a steel wide-flange column of a nominal depth of 250 mm (W 250 shape) to support an axial load P = 800 kN (see figure). The column has pinned ends and length L = 4.25 m. Assume E = 200 GPa and ${\sigma }_y$ = 250 MPa. Note: The selection of columns is limited to those listed in Table F-l(b), Appendix F.
