An interior column is to be designed as a part of an unbraced frame system, located at ground floor. It is to be pin-supported at the foundation end, and it is to be connected by two W14x68 girders and W18x106 column at the other end. All of the members, including the column described, are made of A36. Architectural specifications require that the column is to be designed as a rolled W-section with depth of 21 inches. The column is expected to carry axial compressive load of 300 kN dead load and 350 kN live load. Length of girders is 4 meters and length of columns is 3.0 meters. Select the best section that should be used for the said column. For determining effective length factors, neglect inelastic action; and use major axis moment of inertia for girders and minor axis moment of inertia for columns. Use LRFD specifications from 2015 NSCP Vol. 1
