Abstract

The key problem facing the application of FRP stay cables and tendons is the anchor age. In the first part of the investigation, a model of a potted (bond-type) anchor was proposed, and a parametric analysis of the solution for the distribution of the interfacial shear stress in side the anchor with a sleeve of constant thickness was made. In this, second part, the solution is generalized to consider sleeves with a variable thickness (stepped and tapered), and the parametric analysis is extended. All the results obtained are compared, and the most effective means for decreasing the peak interfacial shear stress in the anchor are highlighted.
