Local Bond Behavior of FRCM Strengthening Systems: Some Considerations about Modeling and Response

The paper presents a study concerning the local bond behavior of FRCM strengthening systems externally applied to structural supports. The aim of the study is to analyze the main parameters influencing the interaction between the reinforcement and the mortar layer and their role. To this purpose, a theoretical approach is performed in order to analyze the main phases characterizing the bond behavior of FRCM-strengthening systems. In particular, the attention has been devoted to the upper mortar layer by analyzing its influence on the bond behavior of FRCM-strengthening systems.
