| Abstract: | In this paper,the 3D Parallel Realistic Failure Process Analysis(RFPA3D-parallel) is employed to investigate the bonding behavior in FRP-concrete interface based on the single shear testing results on FRP-concrete in laboratory.Numerical simulations visually reproduce the complete three-dimensional debonding process and characteristics of FRP bonded to concrete,which is a progressive process induced by meso-scopic cracks initiation and growth and macroscopic fractures form.The damage of FRP-concrete structu... |
