A reinforced concrete beam has a width of 300 mm and an effective depth: of 618 mm. Compressive reinforcement (if required) will be placed at d' = 60mm. fc = 28 MPa and fy = 415 MPa. The beam is to support a factored bending moment of 60C kN-m. Use 2010 NSCP and p = 0.90 for flexure. 1. Calculate the steel ratio for a balanced section. 2. Determine the theoretical steel ratio required for the beam to support the given factored moment 3. Following NSCP requirements, determine the required area of steel reinforcement. 4. Determine the number of 28mm bars required as tension reinforcement. 5. Determine the maximum number of 28mm bars that can be used for given section, if it is singly-reinforced.
