On page 16.1-101 of the LRFD Third edition manual,
Lambda_P = 0.071E/Fy which is equal to
0.071 * 2090420 / 2396 = 61.9
D/t = 32.385 / [0.5*(32.385 - 30.48)] = 34
Since D/t is less than Lambda_P, the section is compact
Mp = the smaller of (Fyld * Z) and (Fyld * 1.5 * S) =
Smaller of (2396 * 941.3), (2396 * 1.5 * 718.04) = 2255355 kg-cm
Moment capacity = 0.9 * Mp = 2029819 kg-cm
Equation H1-1b of the LRFD code
Ratio = (2500*700)/2029819 = 0.862
