A classmate has suggested a beam design that has dimensions of b = 14 in., h = 28 in., and d = 25.5 in. and is reinforced with 4 No. 11 bars. Assuming a cover of 1.5 in. and a stirrup diameter of 0.5 in., does the reinforcement fit within a single row as suggested?

A beam has dimensions of b = 14 in., h = 28 in., d’ = 2.5 in., and d = 25.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 3,400 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 4.812 in., determine the strain in the compression reinforcement, ε’s.
