The 12 in by 20 in column of the frame shown in figure is subjected to an axial load PD=200 kips and a moment Mp= 120 K-ft due to dead load and an axial load P₁= 160 kips and a moment M₁ = 110 K-ft due to live load. The base of the footing is 4 ft below the final grade. Design the footing using fe' = 3 ksi, fy= 40 ksi and the allowable soil pressure is 4 ksi.
