A simply supported beam with dimensions of b = 18 in., h = 24 in., d = 21.5 in., and L = 19 ft supports a uniform service (unfactored) dead load of 2.05 kips/ft including its own self weight plus a uniform service (unfactored) live load of 0.8 kips/ft. The beam is reinforced with three No. 7 Grade 60 bars. The concrete strength is 10,000 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 108 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 128.6 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 4.1961 in.
