A wаll fооting hаs the fоllowing conditions. Determine the depth, d, of the reinforcement. Assume the footing is 5 ft wide, the pressure thаt acts on the bottom of the footing is 5,200 psf, and the reinforcement is a #9 bar spaced every 12 inches.The bottom of the footing is at a depth of 4 ft below grade.The service dead load is 11 kips/ft, and the service live load is 8 kips/ft.The wall is 10 in. thick.The footing is 13 in. thick.The allowable soil pressure, qa, is 4,500 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.
