Experiment research of flexural behavior of reinforced RC beams strengthened with the external prestressed CFRP plates

摘要：

　　Based on the the self-developed prestressed CFRP plate anchorage,the test specimens comprised 5 RC beams strengthened with the way the external prestressed CFRP plates,the research on the different prestressed tension and different span beam about the influence of the bending capacity,ultimate bearing capacity,cross section strain,CFRP strain and deflection of the test reinforced beams on the research.The test results showed that:the externally prestressed CFRP plate can obviously increase of the flexural performance of RC beams,and improve the utilization rate of the strength of the CFRP plate,through the external prestressed anchor of CFRP plate for a tension,reducing the RC beams crack,and improving the ductility of the RC beams.
