A wall footing has the following conditions. Determine the required development length, ld, for the reinforcement. Assume the footing is 4 ft wide, the pressure that acts on the bottom of the footing is 5,400 psf, and the reinforcement is a #7 bar spaced every 12 inches.The bottom of the footing is at a depth of 5 ft below grade.The service dead load is 10 kips/ft, and the service live load is 6 kips/ft.The wall is 10 in. thick.The footing is 16 in. thick.The allowable soil pressure, qa, is 4,600 psf.The soil has a density of 110 lb/ft3.The concrete has a density of 150 lb/ft3.The concrete cover has a thickness of 3 in.f’c = 3,000 psi and fy = 60,000 psi.
