A simply supported beam with dimensions of b = 16 in., h = 24 in., d = 21.5 in., and L = 24 ft supports a uniform service (unfactored) dead load of 1.5 kips/ft including its own self weight plus a uniform service (unfactored) live load of 1.1 kips/ft. The beam is reinforced with three No. 6 Grade 60 bars. The concrete strength is 5,800 psi (normal weight). The beam has Grade 60 No. 3 stirrups. Determine the effective moment of inertia, Ie.The cracked moment Mcr = 73.11 kip-ft, and the maximum applied bending moment due to the combined service loads (dead plus live) Ma = 187.2 kip-ft. The neutral axis location of the cracked beam (measured from the top of the beam) is 4.3481 in.
