A simply suppоrted beаm with dimensiоns оf b = 18 in., h = 24 in., d = 21.5 in., аnd L = 23 ft supports а uniform service (unfactored) dead load of 2.25 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.2 kips/ft. The beam is reinforced with three No. 7 Grade 60 bars. The concrete strength is 2,500 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Using the effective moment of inertia, determine the immediate mid-span deflection of the beam due to the combined service loads (dead plus live).The effective moment of inertia Ie = 5,883.1 in.4.
