Finite Element Analysis of Shearing Bond Behavior of CFRP-Concrete Interface

Abstract:

The debonding behavior at the interface between carbon fiber-reinforced plastic (CFRP) sheet and concrete is a key problem for the application of FRP plate, which has been widely applied in the civil engineering for rehabilitation and retrofitting of conventional structures. This paper presents the nonlinear finite element analysis results of the CFRP-strengthened high-strength concrete member. On the basis of the test, considering of the bond-slip relationship, explicit finite element is used for simulating the shear failure of CFRP-strengthened concrete, obtain three-dimensional deformation development diagram, describe the failure mode and the relationship between the shearing bond behavior and concrete strength. The FE results coincide with the experimental results.
