A 6 m simply supported reinforced concrete rectangular beam is 250 mm wide. The total depth is 600 mm and the effective depth is 500 mm. It is reinforced for tension only with 4 – 20 mm diameter bars. It carries a 120 mm thick slab and 6 m wide. The weight of concrete is 24 kN/m3. fy = 280 MPa and fc’ = 30 MPa. The beam is to be analyzed using the strength design method.
