Experimental Study on Seismic Behavior of CFRP-Strengthened RC Beam-Colum Joints

Abstract:

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.
