T$-02$: A $50-$ft clear$-$span simply supported beam carries a uniform dead load of $75\mathrm{.}5$kip$\frac{s}{f}t($including the self$-$weight of beam$)$ and a live load of $85$kip$\frac{s}{f}t$ as shown in Figure. The beam is reinforced with four bars #$20$ diameters in one row. Design the required shear reinforcement and draw the reinforcement detailing's. Given: $f_c^{\text{'}}=5000$ and $f_y=65000.$
