Popis: International audience; Recent experimental analyses have shown the high performance of the "fiber anchor" applied over FRP to substrate bonded joints to avoid the premature debonding fracture of the reinforcement. In this study, an optical non-destructive measurement method, the Digital Image Correlation, was used to describe the debonding onto the FRP reinforced surface of 36 bricks subjected to Shear Test. A series of samples not-fastened was compared to some series fastened by fiber anchor. The fields data permitted to analyze the stress transfer zone and the effective bond length and to make several considerations about the product stiffness-thickness of the FRP strip.
