Three-dimensional numerical investigation of mixed-mode debonding of FRP-concrete interface using a cohesive zone model
Original language description
As a low-cost high-performance method for concrete structural reinforcement and repair, the external bonding (EB) of fiber-reinforced polymer (FRP) laminates has gradually become popular. But these FRP-reinforced structures usually fail prematurely due to the interfacial debonding. Thus, the mixed-mode debonding behavior of the FRP-concrete interface by a 3D cohesive zone model (CZM) will be analyzed in this study. The 3D CZM provided a detailed description of interfacial damage propagation and friction-sliding evolution during the whole debonding process. Based on the program coding which implements the proposed CZM, numerical models will be built according to the previous experiments. By comparison, the numerical and experimental results showed a good agreement. Besides, the key parameters, which include peeling angle, strength ratio, energy ratio, and friction coefficient, will also be investigated to assess their effect on the interfacial bond capacity.
