Abstract: The most recent report by ACI Committee 440 on externally bonded fiber reinforced polymer (FRP) strengtheningsystems states that systems designed to mechanically anchor FRP should be studied in detail and substantiated by physical testing.To select and design an appropriate anchorage system for use in an FRP strengthening system, it is important that findings fromprevious research studies be known. This paper presents a comprehensive literature review of the performance of differentmechanical anchorage systems used in FRP strengthening applications. Each anchorage system is discussed in terms of its purposeand performance. Advantages and disadvantages of each system are discussed, and areas in need of future research are explored.
