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 6,100 psf.The bottom of the footing is at a depth of 2 ft below grade.The service dead load is 11 kips/ft, and the service live load is 7 kips/ft.The wall is 12 in. thick.The footing is 12 in. thick.The allowable soil pressure, qa, is 5,600 psf.The soil has a density of 130 lb/ft3.The concrete has a density of 150 lb/ft3.The concrete cover has a thickness of 3 in.f’c = 3,900 psi and fy = 60,000 psi.
