Abstract: Anchorage devices can enhance the strength and deformability of reinforced concrete (RC) structures strengthened with fiber-reinforced polymer (FRP) materials. Anchorage can also result in a higher utilization of the desirable strength properties of the FRP. FRP anchors are commonly used in practice as such anchors are particularly well-suited to a wide range of structural forms and FRP applications. While there have been numerous experimental studies reported to date concerned with FRP anchors applied to FRP-strengthened RC structures, the limited amount of associated design rule development has inhibited the rational design and practical application of anchors. An overview of selected FRP anchor design models that have been reported in the literature is presented herein, as well as a commentary on the applicability and limitations of the models. A potential anchor design methodology is developed to illustrate how the different models can be combined towards the rational design of such anchors in FRP strengthening systems. Design examples are also included to demonstrate the enhancement of strength due to anchors and the design of the anchors in common strengthening applications currently available in ACI 440.2R (2008). Finally, shortcomings in the current state of knowledge and topics meriting further research are discussed.
