A wall footing has the following conditions. Determine the critical bending moment, Mu, at the face of the wall. Assume the footing is 4 ft wide and the pressure that acts on the bottom of the footing is 5,600 psf.The bottom of the footing is at a depth of 4 ft below grade.The service dead load is 8 kips/ft, and the service live load is 8 kips/ft.The wall is 16 in. thick.The footing is 16 in. thick.The allowable soil pressure, qa, is 5,800 psf.The soil has a density of 115 lb/ft3.The concrete has a density of 150 lb/ft3.The concrete cover has a thickness of 3 in.f’c = 3,100 psi and fy = 60,000 psi.
