A wall footing has the following conditions. Determine the critical one-way shear, Vu, at a distance of d from the face of the wall. Assume the footing is 3 ft wide, the pressure that acts on the bottom of the footing is 5,600 psf, and the reinforcement is a #7 bar spaced every 12 inches.The bottom of the footing is at a depth of 2 ft below grade.The service dead load is 6 kips/ft, and the service live load is 6 kips/ft.The wall is 14 in. thick.The footing is 11 in. thick.The allowable soil pressure, qa, is 5,000 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.
