**Introduction**

In a rectangular reinforced concrete (RCC) beam section, additional shear may be developed due to torsion. This can lead to a decrease in the overall strength and stability of the beam. However, there are several strategies that can be implemented to reduce this additional shear and improve the performance of the beam. These include increasing the width of the section, increasing the depth of the section, decreasing the depth to width ratio, and increasing the depth of the beam while reducing the width of the beam section.

**1. Increase in Width of the Section**

Increasing the width of the section can help to reduce the additional shear developed due to torsion. This is because a wider section provides more resistance to shear forces. The increased width allows for a greater distribution of the shear forces, resulting in a more efficient load transfer across the beam section. As a result, the additional shear due to torsion is reduced.

**2. Increase in Depth of the Section**

Increasing the depth of the section is another effective way to reduce the additional shear developed due to torsion. A deeper section provides a larger lever arm, which helps to resist the torsional forces more effectively. The increased depth also allows for a greater distribution of the shear forces, resulting in a reduction of the additional shear due to torsion.

**3. Decrease in Depth to Width Ratio**

The depth to width ratio of a beam section is an important factor in determining its ability to resist torsional forces. A decrease in the depth to width ratio can help to reduce the additional shear developed due to torsion. This is because a lower depth to width ratio provides a more balanced distribution of the shear forces, resulting in a more efficient load transfer. As a result, the additional shear due to torsion is reduced.

**4. Increase in Depth of Beam and Reduction in Width of Beam Section**

Another effective strategy to reduce the additional shear due to torsion is to increase the depth of the beam while reducing the width of the beam section. This helps to achieve a more efficient load transfer and a better distribution of the shear forces. The increased depth provides a larger lever arm to resist torsional forces, while the reduced width allows for a more balanced distribution of the shear forces. As a result, the additional shear due to torsion is minimized.

**Conclusion**

In conclusion, the additional shear developed due to torsion in a rectangular RCC beam section can be reduced by implementing various strategies. These include increasing the width of the section, increasing the depth of the section, decreasing the depth to width ratio, and increasing the depth of the beam while reducing the width of the beam section. Each of these strategies helps to achieve a more efficient load transfer and a better distribution of the shear forces, resulting in a reduction of the additional shear due to torsion.
