A wаll fооting hаs the fоllowing conditions. Determine the criticаl one-way shear, Vu, at a distance of d from the face of the wall. Assume the footing is 4 ft wide, the pressure that acts on the bottom of the footing is 4,599 psf, and the reinforcement is a #4 bar spaced every 12 inches.The bottom of the footing is at a depth of 3 ft below grade.The service dead load is 6 kips/ft, and the service live load is 7 kips/ft.The wall is 14 in. thick.The footing is 10 in. thick.The allowable soil pressure, qa, is 4,400 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 = 3,800 psi and fy = 60,000 psi.
