A2.3- a simply supported reinforced concrete beam of rectangular cross-section is shown in Figure 3. The beam
supports a uniform dead load of 20 kN/m (excluding the beam self-weight) and a uniform live load of 20 kN/m.
The beam width is restricted to 400 mm. The maximum aggregate size is 20 mm. We are using 10M bars for
stirrups and 25M bars for tension steel. Concrete is type N with f'c = 35 MPa and fy = 400 MPa. The beam needs
to have 2hr fire rating.
Design the beam for the given load, considering the reinforcement ratio p < 0.5 pb
