A W 14 x 82 interior column in the ground floor having an unsupported height of 5 meters is to support an axial load in the interior of the building where the top of the column is rigidly framed to two (2) way floor beams as shown. All other storeys are spaced 4 meters and adjacent storeys have the same column sections. Use ASTM A992 steel with Fy = 350 MPa. The column is rigidly fixed to the footing. Assume that bracing is provided to prevent side-sway in the weak axis of the column.

1. Compute for the ultimate design capacity of the column.
2. If the column supports 1000 kN service dead load and 500 kN service live load, check the adequacy of the column.
