A reinforced concrete beam has the following properties: beam with, b=320mm effective depth, d=640 mm concrete strength, f'c=25MP reinforcing steel, fy=400 MPa reinforcing steel modulus, Es=200,000 MPa service dead load moment 350=kN-m a. If the beam is to be designed for balanced condition, find the required area of steel reinforcement, in sq. mm. b. Find the maximum design moment in kN-m if the beam is to be designed as singly reinforced.
