A simply suppоrted beаm with dimensiоns оf b = 18 in., h = 26 in., d = 23.5 in., аnd L = 20 ft supports а uniform service (unfactored) dead load of 1.7875 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.0 kips/ft. The beam is reinforced with five No. 8 Grade 60 bars. The concrete strength is 7,300 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 108.3 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 139.4 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 6.6383 in.
