Abstract

Since there exists plastic zone on the crack tip of reinforced beam, it is impossible to use crack instability criterion for brittle materials. Based on the theory of fracture mechanics, by using D-B model and considering the actual construction conditions, this study puts forward a COD criterion-based computing method to make a quantitative analysis of the shear stress of CFRP reinforced interface. The results show that it is feasible to use COD detection value to analyze the shear stress of FRP-to-concrete interface for those elasticity-dominant materials with small size of plastic zone . In actual construction, crack initiation detection COD is simpler to use and easier to measure. It will prevent debonding and prompt the FRP-to-concrete interfacial debonding.
