Post-Tensioning

What is Post-Tensioning?

Post-tensioning is a technique used to pre-stress reinforced concrete. The tensioning provides the member with an immediate and active load-carrying capability. Placement of the tension components can be achieved either internally within the member or externally to the member. Post-tensioning enhances a member’s ability to relieve overstressed conditions in tension, shear, bending, and torsion. The post-tensioning technique can also be used to eliminate unwanted displacements in members and to turn discontinuous members into continuous members.
