The beam is reinforced with $6$ Nos. $25$mm dia. an tension fau. Design the shear reinforcement using vertical stirrups.

$$b=230 mm , d=600 mm ,l=10m, d_c=50 mm , Ast=6-25mm$$

$ =2946mm^2\\ D=d+d_c=650mm \\ self \space ast=(0.23\times0.65)\times 23= 3.73 kn/m$

factored shear force $(V_{UD} )= 1.5 x v \\ = 1.5 x 192.41 \\ = 288.61KNm \\ Z_{uv}=\dfrac {V_{UD}}{b\times d}=\dfrac {288.6\times10^3}{230\times600}=1.92 N/mm^2 \lt 2.8 N/mm^2 \therefore safe \\ pt= \dfrac …
