A wаll fооting hаs the fоllowing conditions. Determine the criticаl bending moment, Mu, at the face of the wall. Assume the footing is 6 ft wide and the pressure that acts on the bottom of the footing is 4,866 psf.The bottom of the footing is at a depth of 3 ft below grade.The service dead load is 15 kips/ft, and the service live load is 7 kips/ft.The wall is 10 in. thick.The footing is 11 in. thick.The allowable soil pressure, qa, is 4,600 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 = 3,700 psi and fy = 60,000 psi.
