1.     Spalling Reinforcement: The spalling stresses leads to stress behind the loaded area of the anchor blocks. This results in the breaking off of the surface concrete. The most likely causes of such types of stresses are Poisson`s effects strain interoperability or by the stress trajectory shapes.

2.      Equilibrium Reinforcements: This type of reinforcements are required where several anchorages exist where the prestressing loads are applied in a sequential manner.

3.     Bursting Reinforcements: These kinds of stresses occur in cases where the stress trajectories are concave towards the line of action of load. In order to reduce such stresses reinforcements in the form of bursting is required.

The three major reinforcement used in prestressing structure are

1. Spalling Reinforcement

2. Equilibrium Reinforcement

3. Bursting Reinforcements.

The process of prestressing is to induced tensile stresses in the reinforcement.

Mainly depending upon the requirement following three type of reinforcements are provided.

1. Busting Reinforcement

2. Equilibrium reinforcement

3. Spalling reinforcement

I agree with our fellow colleagues.

I) Spalling Reinforcement

II) Equilibrium Reinforcements

III) Bursting Reinforcements

Frist we used columns and beams, 2nd we used deep foundation for a big sturcture and 3rd we used pile foundation.
