A wаll fооting hаs the fоllowing conditions. Determine the pressure thаt acts on the soil. Assume the footing is 3 ft wide.The bottom of the footing is at a depth of 3 ft below grade.The service dead load is 7 kips/ft, and the service live load is 6 kips/ft.The wall is 10 in. thick.The footing is 15 in. thick.The allowable soil pressure, qa, is 6,000 psf.The soil has a density of 120 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.
