A wall footing has the following conditions. Determine the minimum cross-sectional area of the reinforcement. Assume the footing is 4 ft wide and the pressure that acts on the bottom of the footing is 6,300 psf.The bottom of the footing is at a depth of 5 ft below grade.The service dead load is 13 kips/ft, and the service live load is 6 kips/ft.The wall is 14 in. thick.The footing is 15 in. thick.The allowable soil pressure, qa, is 5,400 psf.The soil has a density of 120 lb/ft3.The concrete has a density of 150 lb/ft3.The concrete cover has a thickness of 3 in.f’c = 4,000 psi and fy = 60,000 psi.
