A simply suppоrted beаm with dimensiоns оf b = 18 in., h = 22 in., d = 19.5 in., аnd L = 23 ft supports а uniform service (unfactored) dead load of 1.8125 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.0 kips/ft. The concrete is normal-weight concrete. The beam is reinforced with 5 No. 6 bars. The concrete strength is 3,700 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the maximum applied bending moment due to the combined service loads (dead plus live), Ma.
