A simply suppоrted beаm with dimensiоns оf b = 16 in., h = 22 in., d = 19.5 in., аnd L = 25 ft supports а uniform service (unfactored) dead load of 1.766667 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.0 kips/ft. The beam is reinforced with four No. 5 Grade 60 bars. The concrete strength is 7,000 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 67.49 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 216.1 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 3.8417 in.
