Abstract : Debonding of fiber reinforced polymer (FRP), particularly in shear, is a major failure mode when using FRP sheets to strengthen concrete structures. This paper discusses an experimental study on the behaviour of shear deficient reinforced concrete (RC) beams strengthened using external carbon fiber reinforced polymer (CFRP) wrapping with new end anchorage technique to eliminate the deboding failure. The main objective of this study is to evaluate the effectiveness of anchorage system for RC beams strengthened using externally bonded (EB) FRP methods. The outcome of this experimental study emphasizes the contribution of end anchorage system on shear strengthening of RC beams, which can achieve a superior contribution in shear resistance compared to the specimens strengthened using EB FRP without end anchorage system. The beam strengthened with CFRP wrapping shows better performance in load carrying capacity and ductility as compared with the control beam.
