A wall footing has the following conditions. Determine the depth, d, of the reinforcement. Assume the footing is 5 ft wide, the pressure that acts on the bottom of the footing is 5,120 psf, and the reinforcement is a #5 bar spaced every 12 inches.The bottom of the footing is at a depth of 5 ft below grade.The service dead load is 12 kips/ft, and the service live load is 7 kips/ft.The wall is 16 in. thick.The footing is 10 in. thick.The allowable soil pressure, qa, is 4,800 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 = 3,300 psi and fy = 60,000 psi.
