A W shape is used as a column to support a service $DL=405KN$ and a service $LL=500KN.$ The member

is $8\mathrm{.}25m$ long and is pinned at the ends. It is supported in the weak direction at a point $3\mathrm{.}65m$ from the

top. $F_y=345$MPa and $F_u=450$MPa. Local stability is not a requirement. Use LRFD$.$
