A wall footing has the following conditions. Determine the minimum cross-sectional area of the reinforcement. Assume the footing is 5 ft wide and the pressure that acts on the bottom of the footing is 4,640 psf.The bottom of the footing is at a depth of 2 ft below grade.The service dead load is 10 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 4,000 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 = 3,400 psi and fy = 60,000 psi.
