A wall footing has the following conditions. Determine the critical bending moment, Mu, at the face of the wall. Assume the footing is 3 ft wide and the pressure that acts on the bottom of the footing is 7,333 psf.The bottom of the footing is at a depth of 4 ft below grade.The service dead load is 9 kips/ft, and the service live load is 7 kips/ft.The wall is 10 in. thick.The footing is 10 in. thick.The allowable soil pressure, qa, is 6,000 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 = 3,800 psi and fy = 60,000 psi.
