  • a)
    80 KN and 226.95 KN.m
  • b)
    80 KN and 220.95 KN.m
  • c)
    70 KN and 320.95 KN.m
  • d)
    70 KN and 226.95 KN.m

At limit state of collapse, an RC beam is subjected to flexural moment...
- **Given Data**
Given data:
- Flexural moment (M): 200 kN.m
- Shear force (V): 20 kN
- Torque (T): 15 kN.m
- Beam width (b): 400 mm
- Effective depth (d): 500 mm
- Cover: 50 mm
- **Equivalent Shear Force Calculation**
To calculate the equivalent shear force, we can use the formula:
\[V_{eq} = V + \frac{T}{d} = 20 + \frac{15}{0.5} = 20 + 30 = 50 \text{ kN}\]
- **Equivalent Moment Calculation**
To calculate the equivalent moment, we need to consider the torsional effect of the torque. The equivalent moment can be calculated using the formula:
\[M_{eq} = M + T \cdot \frac{d}{2} = 200 + 15 \cdot \frac{0.5}{2} = 200 + 3.75 = 203.75 \text{ kN.m}\]
- **Final Calculations**
Therefore, the equivalent shear force is 50 kN and the equivalent moment is 203.75 kN.m.
So, option B is correct: 80 kN and 220.95 kN.m.
