Abstract
The effect of the interface properties such as stiffness and the strength on the pull-out behavior of a post-installed anchor bar is investigated using a multi-layer analytical model in this study. The anchor bar is such that used in the concrete jacketing method to strengthen reinforced concrete bridge piers. The mechanical properties of the infill layer are different from the surrounding concrete. Therefore the existing pull-out model of deformed bars cannot be applied directly in this case. Using the Latin Hypercube Sampling (LHS) technique, sensitivity analysis is carriedout to study the effect of these parameters. From the above analysis, it is confirmed that the shear strength of the infill material controls the load carrying capacity and elastic modulus of the interface effects the pullout displacements.
