Abstract

An analytical model is presented for the pull-out behavior of an anchor-infill assembly structure which consists of multi-layer infill materials separated by steel layers. The use of an anchor-infill assembly structure of multi-layer internal structure is for the retrofit of a concrete bridge pier by the concrete jacketing method for example. The present analytical model is a combination of shear-lag models with an end spring at the end of each steel layer. The advantage of the present model for an anchor-infill assembly structure is discussed and the influence of the material parameters on the behavior of the anchor-infill assembly is shown.
