In a beam of 300 mm wide and 500 mm effective depth, the value of the design shearing force at the critical section is 270 kN. The permissible shear stress in concrete is 0.4 N/mm2 depending on the percentage of steel content. Which of the following statement is true?
1
The shear reinforcement will be designed for a shear force of 30 kN
2
The shear reinforcement will be designed for a shear force of 210 kN
3
The shear reinforcement will be designed for a shear force of 270 kN
4
The section must be redesigned
