DESCRIPTION<\/strong><\/h2>\n

 <\/p>\n

Rehabilitation and strengthening of infrastructures and existing buildings represent effective contributions to the extension of their service life and global sustainability, therefore contributing to circular economy. There is a need to take advantage of the new emerging technologies and innovative materials, such as Fibre Reinforced Polymer (FRP), with the purpose of mitigating deterioration and efficiently managing maintenance efforts on civil structures.<\/p>\n

The structural behaviour of concrete elements strengthened with FRP greatly depends on the bond behaviour of the concrete-FRP joint. This bond behaviour has been extensively studied in the last years, showing that premature debonding of the FRP is the most common failure mode, leading to very restrictive practical design recommendations, and resulting in a severe underutilization of the FRP mechanical properties. Anchorage of the FRP, as a method to delay or prevent the critical failure mode of FRP, is one means to significantly improve the efficiency of FRP systems and hence provide a solution to these shortcomings.<\/p>\n

The project aims to study new anchorage systems applicable to elements strengthened in flexure with FRP laminates, putting special attention on the debonding mechanisms of the FRP-concrete joint. The typical techniques of Externally Bonded Reinforcement and Near Surface Mounted will be studied, and different environmental conditions and loading circumstances (static and fatigue loading) will be studied and assessed. Bond and flexural tests will be performed in order to evaluate the effects on the load-deflection behaviour, mode of failure and residual bond capacity. From the obtained experimental results, it is expected to develop bond laws that allow considering the aforementioned parameters on the anchorage contribution, and can lead to analytical and numerical models able to simulate the behaviour of concrete structures strengthened with anchored FRP reinforcement and to be used in practical design.<\/p>\n
