**Introduction:**
In a rectangular RCC beam section, additional shear developed due to torsion can be reduced by various methods. These methods 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 helps to distribute the shear stresses over a larger area, thereby reducing the intensity of shear stress. This is because increasing the width increases the lever arm for the applied shear forces, resulting in a reduced shear stress.
**2. Increase in Depth of the Section:**
Increasing the depth of the section increases the moment of inertia of the beam, which helps in resisting the applied torsional forces. This results in a reduction in the shear stress developed due to torsion. Additionally, increasing the depth also increases the lever arm for the applied shear forces, further reducing the shear stress.
**3. Decrease in Depth to Width Ratio:**
The depth to width ratio of a beam section is an important parameter that affects its resistance to torsional forces. Decreasing the depth to width ratio can help in reducing the shear stresses developed due to torsion. This is because a smaller depth to width ratio provides a more compact section, which is less prone to torsional effects.
**4. Increase in Depth and Reduction in Width of the Beam Section:**
Increasing the depth of the beam and reducing the width of the beam section simultaneously helps in reducing the shear stresses developed due to torsion. This is because both actions increase the lever arm for the applied shear forces and also increase the moment of inertia of the beam, which collectively enhance the beam's resistance to torsional forces.
**Conclusion:**
To summarize, additional shear developed due to torsion in a rectangular RCC beam section can be reduced by 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. These methods help in distributing the shear stresses, increasing the lever arm, and enhancing the beam's resistance to torsional forces.
