Direction: A reinforced concrete beam of rectangular cross section of breadth 230 mm and effective depth 400 mm is subjected to a maximum factored shear force of 120 kN. The grade of concrete, mains steel and stirrup steel are M20, F415 and Fe250 respectively. For the area of main steel provided, the design shear strength τc as per IS : 456-2000 is 0.48 N/mm2. The beam is designed for collapse limit state.
-
In addition, the beam is subjected to a torque whose factored value is 10.90 kNm. The stirrups have to be provided to carry a shear (kN) equal to
-
- 50.42
- 130.56
- 151.67
- 200.23
Correct Option: C
| Equivalent SF = | b |
| = | = 75.82 kN | 230 |
Total SF = 75.82 + 75.84 = 150.67 kN
