A wаll fооting hаs the fоllowing conditions. Determine the depth, d, of the reinforcement. Assume the footing is 4 ft wide, the pressure thаt acts on the bottom of the footing is 5,300 psf, and the reinforcement is a #8 bar spaced every 12 inches.The bottom of the footing is at a depth of 5 ft below grade.The service dead load is 7 kips/ft, and the service live load is 8 kips/ft.The wall is 14 in. thick.The footing is 14 in. thick.The allowable soil pressure, qa, is 5,500 psf.The soil has a density of 125 lb/ft3.The concrete has a density of 150 lb/ft3.The concrete cover has a thickness of 3 in.f'c = 3,600 psi and fy = 60,000 psi.
