1. Spalling Reinforcement :- 

These stresses are induced by strain incompatibility with Poisson’s effects or by the shape of stress trajectories.

2. Equilibrium Reinforcement :-

Equilibrium reinforcement is required where there are several anchorages in which prestressing loads are applied sequentially.

3. Bursting Reinforcement :-

Tensile stresses are induced during prestressing operation and the maximum bursting stress.
Trajectories are concave towards Action of the loads. Reinforcement is needed to resist these lateral tensile forces.
