Characteristic strength of concrete, Civil Engineering

In addition to its own weight, the beam in Figure is to carry a uniformly distributed live load of 12 kN/m. Figure 1 also shows the cross-sectional details of the beam.

Design and detail the reinforcement for the section just left of the support at B. Take the characteristic strength of concrete fc′ = 32 MPa and the cover to the centre of the extreme layer of bars as 50 mm. Use only N28 bars noting that reinforcing bars may be spread over the width of the flange.
