A prismatic beam having 275 mm x 500 mm is reinforced for flexure at the bottom with 5-ϕ20 mm with an effective depth of 420 mm. It is simply supported over a clear span of 6 m and designed to support a total factored uniformly distributed load of 35 kN/m over the entire span. Concrete weighs 24 kN/m3, Concrete strength f’c = 21 MPa and rebar strength fy = 280 MPa. Determine the required nominal shear force the stirrups must sustain based on the critical shear force at a section located distance "d" from face of support.
