A wall footing has the following conditions. Determine the moment capacity, Mn, of the footing. Assume the footing is 4 ft wide, the pressure that acts on the bottom of the footing is 4,900 psf, and the reinforcement is a #4 bar spaced every 12 inches.The bottom of the footing is at a depth of 2 ft below grade.The service dead load is 7 kips/ft, and the service live load is 7 kips/ft.The wall is 10 in. thick.The footing is 12 in. thick.The allowable soil pressure, qa, is 4,400 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.
