Question

While checking shear resistance of reinforced concrete beams for limit state of collapse as per IS:456, which one of the following nominal shear stress recommendations is to be adhered to?
(V $_{u}$ is shear force at vertical cross-section, 'b' and 'd' are overall breadth and effective depth of beam respectively)
