A beаm hаs dimensiоns оf b = 18 in., h = 30 in., аnd d = 27.5 in. and is reinfоrced with 4 No. 5 bars. The concrete strength is 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. If the depth of the compressive stress block is a = 1.736695 in. and the strain in the reinforcement is εs = 0.037378, determine the strength φMn for this beam. Assume the transverse reinforcement is not spirals.
