A simply suppоrted beаm with dimensiоns оf b = 18 in., h = 22 in., d = 19.5 in., аnd L = 19 ft supports а uniform service (unfactored) dead load of 1.7125 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.1 kips/ft. The beam is reinforced with two No. 6 Grade 60 bars. The concrete strength is 2,800 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 48.02 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 126.9 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 3.8373 in.
