A wаll fооting hаs the fоllowing conditions. Determine the required cross-sectionаl area of shrinkage and temperature reinforcement. Assume the footing is 6 ft wide, the pressure that acts on the bottom of the footing is 4,533 psf, and the reinforcement is a #6 bar spaced every 12 inches.The bottom of the footing is at a depth of 4 ft below grade.The service dead load is 12 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 4,300 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 = 3,400 psi and fy = 60,000 psi.
