Abstract

: In this study, a theoretical model is deve loped to simulate the re-anchorage of a ruptured

bonded post-tensioning tendon. This includes estimating the re-anchorage length and stress distribution over

the tendon. The model accounts for equilibrium and compatibility conditions at the steel-grout, grout-duct and

duct-concrete interfaces as well as the effect of axial stresses in the strand and its confining materials, i.e.

grout, duct and concrete. Formulation of the model is based on the elastic theory of thick-wall cylinders and

the Coulomb friction model. The model has been validated against an axi-symmetrical Finite Element (FE)

model, the UK Highway Agency’s BA51/95 model and previous experimental data. The models had been

compared with the UK Highway Agency’s BA51/95 model and previous experimental data.
