Question: A rectangular beam having a with of 3 5 0 mm and total depth of 6 0 0 mm is reinforced with 4 3 6

A rectangular beam having a with of 350 mm and total depth of 600 mm is reinforced with 436-mm diameter tension bars (only). Using effective depth of 530 mm and modular ratio of 8, Determine the effective moment of inertia to be used for this rectangular beam. The unfactored maximum moment is 240 kN-m. fc=28 MPa, and fy=415 MPa. Answer: 4394811772 mm4
