Torsion Resisting Capacity of RC Section:
Torsion is a twisting force that occurs in a structure when it is subjected to a load. The torsion resisting capacity of a reinforced concrete (RC) section refers to its ability to resist twisting forces.
Factors affecting torsion resisting capacity:
There are several factors that affect the torsion resisting capacity of an RC section. These factors include:
1. Stirrup spacing
2. Longitudinal bars
3. Stirrup and longitudinal steel
Effect of stirrup spacing:
Stirrups are vertical bars that are placed in an RC section to resist shear forces. The spacing between stirrups affects the torsion resisting capacity of an RC section. When the stirrup spacing is decreased, the torsion resisting capacity of the RC section also decreases.
Effect of longitudinal bars:
Longitudinal bars are placed in an RC section to resist bending forces. The number of longitudinal bars affects the torsion resisting capacity of an RC section. When the number of longitudinal bars is increased, the torsion resisting capacity of the RC section decreases.
Effect of stirrup and longitudinal steel:
The torsion resisting capacity of an RC section depends upon the amount of stirrup and longitudinal steel used. When the amount of stirrup and longitudinal steel is increased, the torsion resisting capacity of the RC section also increases.
Conclusion:
In conclusion, the torsion resisting capacity of an RC section depends upon several factors. While stirrup spacing and longitudinal bars have a negative effect on torsion resisting capacity, the amount of stirrup and longitudinal steel has a positive effect.
