The W14 \(\times 53\) structural A-36 steel column supports an axial load of 80 kip in addition to an eccentric load \(P\). Determine the maximum allowable value of \(P\) based on the AISC equations of Sec. 13.6 and Eq. 13-30. Assume the column is fixed at its base, and at its top it is free to sway in the \(x-z\) plane while it is pinned in the \(y-z\) plane.
