الملخصThe contribution of ruptured tendons to the residual strength of bonded posttensioned concrete structures is currently assessed based on pretensioned concrete bond models. However, this approach is inaccurate due to the inherent differences between pretensioned and posttensioned concrete. In this paper, a nonlinear three-dimensional (3D) finite-element model is developed for the reanchoring of a ruptured tendon in posttensioned concrete. The model is validated using full-field displacement measurement from 33 posttensioned concrete prisms and previous experimental data on beams from the literature. The influence of different parameters is investigated, including tendon properties (i.e., diameter, roughness), duct properties (i.e., diameter, thickness, material), initial prestress, concrete strength, grout strength, grout voids, stirrups, and strands on the tendon reanchorage. The most influential parameters are found to be tendon and duct properties. 1 2017 American Society of Civil Engineers.
