A beam has dimensions of b = 18 in., h = 10 in., and d = 7.5 in. and is reinforced with 4 No. 7 bars. The concrete strength is 3,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 2.914 in., does the reinforcement yield?

A concrete cover of at least two bar diameters is required to sufficiently bond the reinforcement to the concrete.

In analysis, there are many possible answers. One determines the beam strength given several factors such as concrete strength, cross section, reinforcement size, location, and yield strength.

For the initial analysis-design cycle, total beam depths are typically in the range of L/18 to L/12, where L is the center-to-center span length of the beam.

A beam has dimensions of b = 14 in., h = 30 in., d’ = 2.5 in., and d = 27.5 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 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the neutral axis is c = 5.68 in., determine the force in the compression reinforcement, Cs.
