摘要：
Based on the experiment research of three concrete beam-column joints strengthened with anchored Carbon Fiber Reinforced Polymer (CFRP) under low reversed cyclic loading, this paper studys on the mechanical properties and deformation characteristics of reinforced nodes, and also makes the anylasis of the influence mechanism of shear bearing capacity of beam-column joints with longitudinal land transverse carbon fiber reinforcement amount in the beam-colunm ends. The results show that: the bolt-plate lock-anchored CFRP hoops can effectively delay the debonding of the longitudinal CFRP at the end of beam, significantly increase the energy dissipation capacity of the joint.
