A rectangular concrete beam of width 600 mm is limited by architectural considerations to a maximum total depth 400 mm. It must carry a total factored load moment Mu = 540 kN-m. Design the flexural reinforcement for this member, using compression steel if necessary. Allow 75 mm to the center of the bars from the compression or tension face of the beam, and the diameter of stirrups is 12 mm. Material strengths are fy = 420 MPa and f'. = 28 MPa. 1. Determine the depth of the compression block, mm. * 2. Required compression steel reinforcement, mm^2. * 3. Required tension steel reinforcement, mm^2. *
