Retrofitting RC Joints Using Flange-Bonded FRP Sheets
Abstract Improving the performance of beam–column connections is a useful method to retrofit a deficient reinforced concrete (RC) frame. This paper presents the results of experimental and numerical studies conducted to assess the ability of CFRP overlays to improve the seismic capacity of RC joints. Two, full-scale RC exterior joints of a moderate ductility moment resisting frame are designed, fabricated and tested under monotonic pushover loads before and after retrofitting. The test results are then used to develop and verify a detailed numerical model of the beam–column connection. A flange-bonded fibre-reinforced polymer (FRP) retrofitting scheme is used for improving the capacity of the joint. In a parametric study, the optimal thickness of FRP sheets needed for relocation of the plastic hinge away from the column face is then determined. Results of the experimental and numerical analysis show that the retrofitting method improves the capacity and performance of the overall RC beam–column joint.
