A wall footing has the following conditions. Determine the required cross-sectional 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.

A simply supported beam with dimensions of b = 18 in., h = 30 in., d = 27.5 in., and L = 24 ft supports a uniform service (unfactored) dead load of 1.7625 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.4 kips/ft. The concrete is normal-weight concrete. The beam is reinforced with 5 No. 8 bars. The concrete strength is 5,800 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the maximum applied bending moment due to the combined service loads (dead plus live), Ma.

A simply supported beam with dimensions of b = 18 in., h = 22 in., d = 19.5 in., and L = 21 ft supports a uniform service (unfactored) dead load of 1.4125 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The concrete is normal-weight concrete. The beam is reinforced with 2 No. 5 bars. The concrete strength is 9,100 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the maximum applied bending moment due to the combined service loads (dead plus live), Ma.      

Because the designer has little control over the arrangement of the bars in a circular column, the interaction diagram should be computed for the least favorable bar orientation.

net cell voltage = (reduction potential reaction at cathode) – (reduction potential reaction at anode) Q = I x t = n x F mass = moles x molar mass F = 96485 C/mol e- surface area = length x width volume = length x width x depth   a) compare the corrosion of iron with the corrosion of copper. b) Describe and compare the following three methods of corrosion prevention i) painting ii) electroplating iii) using a sacrificial anode
