State of Research on Seismic Retrofit of RC Beam-Column Joints with Externally Bonded FRP

Much research has been directed recently toward understanding and promoting use of externally applied fiber-reinforced polymer (FRP) for seismic retrofit of reinforced concrete (RC) structures. In this paper, a comprehensive review and synthesis of published experimental studies on the seismic rehabilitation of RC frame beam-column joints with FRP is presented, and the issues that need to be addressed for further research are discussed. In addition, the paper presents a simple design model for predicting the contribution of the FRP to the shear strength of retrofitted joints. The key element in the model is the derivation of an expression for the effective FRP strain, based on calibration of test data reported in the literature. 54 tests carried out worldwide are considered in the review, and a database of the published studies, encompassing all relevant design parameters, is assembled. The reported test results confirm the structural effectiveness of the FRP strengthening technique for the seismic retrofit of RC joints. However, there are some gaps which should be addressed (i.e., there is a lack of a rationale explanation of the resistance mechanisms involved in the beam-column joints retrofitted with FRP). Such a rational explanation is a prerequisite for the development of more comprehensive and rigorous design procedures.
