You are task to design a rectangular section for a simply supported girder of a reinforced concrete bridge. From the structural analysis, the factored moment at the critical section was computed at 323 kN-m. Space restrictions limit your sectional dimensions to 300 mm width and 500mm total depth. With these permissible dimensions, select reinforcement to provide the required moment strength following the ACI Code provisions for the strength reduction factor, ∅. Use fy = 420 MPa and fc’ = 34 MPa.
