Situation $2.$

A W$14$x$90$ of A$992$ steel is used as a pin$-$connected column. The $30$ft long column is braced at

mid$-$height with respect to its weak axis. Determine the axial compressive load. $($ASD & LRFD$)$

Properties of W$14$x$90$:

$A=26\mathrm{.}5i{n}^2$

$d=14\mathrm{.}0in.$

$b_f=14\mathrm{.}5in.$

$t_f=0\mathrm{.}710in.$

$t_w=0\mathrm{.}440in.$

$r_x=6\mathrm{.}14in.$

$r_y=3\mathrm{.}70in.$

$\frac{b_f}{2}{t}_f=10\mathrm{.}2$

$\frac{h}{t_w}=25\mathrm{.}9$
