The bond between concrete and FRP reinforcement plays an important role in the design of strengthening of existing structures. As a brittle material, FRP shows a lack of ductility, and the failure mode occurs suddenly without preceding yielding. Experimental and theoretical researches in this field are always necessary and interesting because of techniques are still new and suitable models are needed for a reliable design. In particular, bond between concrete and FRP is still an open problem because of the lack of a standard test; besides the great variability of parameters involved make difficult the assessment of a bond law of general validity. In this paper an experimental and theoretical investigation on bond between FRP sheets and concrete was carried out and results presented.

Abstract
The bond between concrete and FRP reinforcement plays an important role in the design of strengthening of existing structures. As a brittle material, FRP shows a lack of ductility, and the failure mode occurs suddenly without preceding yielding. Experimental and theoretical researches in this field are always necessary and interesting because of techniques are still new and suitable models are needed for a reliable design. In particular, bond between concrete and FRP is still an open problem because of the lack of a standard test; besides the great variability of parameters involved make difficult the assessment of a bond law of general validity. In this paper an experimental and theoretical investigation on bond between FRP sheets and concrete was carried out and results presented.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
