| 要旨 | A numerical analysis, with Nonlinear Fracture Mechanics (NLFM) based on the fracture energy criterion, is conducted to simulate the bond failure modes observed in the experiment and investigate the bonding mechanism along FRP-concrete interface. Through a Parametric analysis on bond strength and fracture energy of the FRP-concrete interface, concrete fracture energy and initial imperfections in the concrete beams, it is shown that the bond strength is mainly responsible for the initiation of bond failure and the propagation of debonding is govemed by the fracture energy of the interface. |
