Initial Strain = Concrete Strain+Residual Strain
ε_pi = ε_c+ε_po

What is Pre-Tensioning?

This process involves the stressing of wires or cables by anchoring them at the end of a metal form, which may be up to 120 m in length. Hydraulic jacks stress the wire as required, often adding 10% to accommodate creep and other pre-stress losses that may be incurred.
