Question

A prismatic beam having 250 mm x 500 mm is reinforced for flexure at the bottom with 5-ϕ20 mm with an effective depth of 380 mm. It is simply supported over a clear span of 5.5 m and designed to support a total factored uniformly distributed load of 32 kN/m over the entire span. Concrete weighs 24 kN/m³, Concrete strength f’_c = 21 MPa and rebar strength fy = 280 MPa.
