The width and effective depth of a reinforced concrete beam is $$250$$ $$mm$$ and $$440$$ $$mm$$ respectively. The beam is provided with $$4$$ number of $$20$$ $$mm$$ bars in the tension zone. The beam is subjected to a shear force of $$150$$ $$kN$$ (Factored). Check the requirement of shear reinforcement and provide if required. Grade of concrete is $$M20$$ and that of steel is $$Fe415.$$ The shear strength of concrete for different percentage of tensile steel are as below $$8$$ $$mm$$ diameter vertical stirrups are available.
$$\left[ {{V_{us}} = 0.87\,\,{f_y}{A_{sv}}\,\,d/{S_v}} \right.$$ and $${\left( {{A_{sv}}/{S_v}} \right) \ge 0.4b/{f_y}}$$ with the terms having usual meaning $$\left. \, \right]$$
