What are the advantages of prestressed concrete beams compared with ordinary concrete beams? 1.

Solution

Prestressed concrete structures have larger load carrying capacities than ordinary concrete due to prestress compression forces.

Prestressed concrete have an initial camber (upward deflection) due to prestressing bars/strands which greatly reduces the deflection due to applied loads, making them ideal for large spans without much supports.

Prestressed concrete have negligible tensile cracks which enhances the serviceability and preventing steel corrosion.

Due to prestress compression forces the shear capacity of structure get enhanced

In almost all design codes the contribution of concrete to tensile strength is neglected. In Prestressed concrete this is taken into account.
