A simply supported 6 ft. long SSMA 50 ksi 800S250-43 column
subjected to an axial compression load(concentrically loaded).
Braced against buckling about x- and y-axis at both ends. Braced
against torsion at the center and both ends of the column.
Kx=Ky=Kt=1.0, Fy=50 ksi.
1. Determine the nominal strength, Pn, assume Ae=0.3429 in^2 at compressive stress Fn, Use the manual calculation(Effective Width Method) for Pne, PnL, and Pnd. Use the direct strength Method for Pne, PnL, Pnd.
2. Determine the available compression strength for ASD and LRFD design for the two Pn results from step 1.
