V. AISC 360-05 Built up I E.2
Details
From reference (2):
Verify that a built-up, ASTM A572 grade 50, column with PL1in.×8in. flanges and a PL1/4in.×15in. web is sufficient to carry a dead load of 70 kips and live load of 210 kips in axial compression. The column length is 15 ft and the ends are pinned in both axes.
