Question $7\mathrm{.}5\mathrm{.}4$

An A$992$ steel W$14$ x $109$ column, spanning $18$ feet, is utilized within an unbraced frame. Initial axial load and end moments are derived from a first$-$order analysis of gravity loads $($combining dead and live loads$),$ with wind load effects similarly assessed. The frame maintains symmetry, and gravity loads are symmetrically distributed. All loads and moments are considered at service conditions, with bending moments occurring about the strong axis. Effective length factors are assumed to be $1\mathrm{.}0,$ and member stiffness is reduced. Solution approach follows LRFD methodology. Please solve and show all calcs, will upvote. Thank you.
