Design a square individual column footing (reinforced concrete) to support a 16-in.-square reinforced concrete tied interior column. Service loads are 200 kips dead load and 160 kips live load. Both column and footing have f′c = 4000 psi and fy = 60,000 psi. The allowable soil pressure is 5000 psf, and we = 100 lb/ft3. The bottom of the footing is to be 4 ft below grade. The column is reinforced with eight No. 7 bars.
