A rectangular section is limited to a size of b = 350 mm and d = 630 mm to carry a dead load moment of 350 kN‧m and a live load moment of 600 kN‧m. Assume that bars in compression will be placed at 80 mm from the compression face. Given f’c = 28 MPa and fy = 415 MPa. Load factors are 1.2 for dead load and 1.6 for live load for ultimate strength design. Determine the amount of compression reinforcement required if the tension reinforcement is 6,870 mm2 maintaining a tensile strain of 0.005.
