A rectangular column (20'x16') carries an axial load PD =110 K and a moment MD =120 K.ft due to dead load and an axial load PL =220 K and a moment ML =100 K.ft due to live load. The column is part of a frame that is braced against sides-way and bent in single curvature about its major axis. The unsupported length of the column is lc =22 ft, and the moments at both ends of the column are equal. Design this column to satisfy the requirements, using f 'c = 4ksi and fy =60 ksi. %3D
