A beаm hаs dimensiоns оf b = 18 in., h = 24 in., аnd d = 21.5 in. and is reinfоrced with 2 No. 7 bars. The concrete strength is 3,100 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 1.518027 in. and the strain in the reinforcement is εs = 0.033116, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
