A beam has dimensions of b = 18 in., h = 22 in., and d = 19.5 in. and is reinforced with 3 No. 8 bars. The concrete strength is 4,600 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 2.02046 in. and the strain in the reinforcement is εs = 0.020742, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
