Design of Post-Tensioned Girder Anchorage Zones

Post-tensioning is a form of prestressed concrete in which high-strength steel strands are cast into a concrete slab or beam and tensioned to a high degree of stress following curing. The tensioned strands are anchored at either end, resulting in compression of the concrete between the anchor points.

Prestressed Concrete: Meaning, Advantages and System

Anchorage as the name signifies is a component of post tensioning system which is used to anchor the tendons into the concrete while terminating or joining two tendons. Main function of anchorage is to transfer the stressing force to the concrete once the stressing process is completed.
