$4\mathrm{.}4-1($use $108\frac{1}{4})$

Local Stability

$4\mathrm{.}4-1$ An HSS $108\frac{3}{16}$ is used as a compression member with one end pinned and the

other end fixed against rotation but free to translate. The length is $12$ feet. Compute

the nominal compressive strength for A$500$ Grade B steel $(F_y=46$ksi $).$ Note that this

is a slender$-$element compression member, and the equations of AISC Section E$7$ must

be used.
