In order to explore the reinforced concrete( RC) beam-column joints strengthened by carbon fiberreinforced polymer( CFRP) sheets,the finite element( FE) method was used to investigate the shear behavior and mechanism of the strengthened joints. Two strengthening schemes were included in FEM models,which had been verified by tests. The comparison between simulation and test results showed that the FE method used in the analysis was suitable. The failure modes of the joints,the concrete stress distribution in...
