  • Five RC beams strengthened with CFRP using MOC were tested.Crack patterns, failure modes, strength improvements and stiffness behavior were studied.In the mean time, the influence of the layer of CFRP on the performance of strengthened beams was also investigated.The test results show that using MOC as the adhesive to bond CFRP to an RC member is executable.Load-bearing capacity of the RC beams increased with the number of layers of CFRP while the ductility of those beams is reduced compared to the control beam.The failure modes changed from rupture of CFRP to CFRP delamination by increasing the layer.
