A simply suppоrted beаm with dimensiоns оf b = 16 in., h = 22 in., d = 19.5 in., аnd L = 22 ft supports а uniform service (unfactored) dead load of 1.366667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The beam is reinforced with five No. 6 Grade 60 bars. The concrete strength is 4,300 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 52.9 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 131.1 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 5.4711 in.
