Prevent sudden failure of providing minimum tension steel in RCC beam is required.

Minimum Tension Steel in RCC Beam

Introduction:
Reinforced Cement Concrete (RCC) beams are important structural members that are widely used in construction. The RCC beams are designed to withstand bending, shear, and compression forces. The tensile strength of concrete is very low, so additional reinforcement is provided in the form of steel bars. The steel bars are placed at the bottom of the beam where tensile forces are maximum. The minimum tension steel in RCC beam needs to be provided to prevent sudden failure.

Reasons for Providing Minimum Tension Steel:
The minimum tension steel in RCC beam needs to be provided to prevent sudden failure. The following are the reasons for providing minimum tension steel:

1. Prevent sudden failure:
The minimum tension steel in RCC beam needs to be provided to prevent sudden failure. The tensile strength of concrete is very low, so it can crack under tensile stresses. The steel bars are placed at the bottom of the beam to resist the tensile stresses. If the minimum tension steel is not provided, the beam can fail suddenly due to cracking of concrete under tensile stresses.

2. Control excessive deflection:
The minimum tension steel in RCC beam can also control excessive deflection. The deflection of the beam depends on various factors such as the span of the beam, the load on the beam, and the stiffness of the beam. The steel bars at the bottom of the beam can increase the stiffness of the beam and reduce the deflection.

3. Control surface cracks:
The minimum tension steel in RCC beam can also control surface cracks. The surface cracks can occur due to the shrinkage of concrete or temperature variations. The steel bars at the bottom of the beam can resist the tensile stresses and prevent surface cracks.

Conclusion:
The minimum tension steel in RCC beam needs to be provided to prevent sudden failure, control excessive deflection, and control surface cracks. The steel bars are placed at the bottom of the beam where tensile forces are maximum. The amount of minimum tension steel depends on various factors such as the span of the beam, the load on the beam, and the design requirements.
