Design a column in a braced frame to support a dead load PD= 800 kips and MD= 50 K-ft and a live load PL= 350 kips and ML= 30 K-ft. The column height is 18 ft. The concrete strength F'. = 6,000 psi and reinforcement having a yield strength Fy = 60,000 psi. Due to architectural restrictions, the largest column dimension cannot exceed 20 in. The column is pinned at the bottom (i.e. M1 =0 and K=1). If required, consider the slenderness effect and determine the column size and the number of #14 bars required. Do not consider biaxial bending. (Use diagram R6.60.8)
