Assessment of the experimental and numerical bond-slip law of various strengthening systems in reinforced concrete elements

With the emergence and diversity of various strengthening methods in fibre-reinforced polymer (FRP) strengthened reinforced concrete (RC), understanding and comparing the bond behaviour and active bond mechanisms of these different methods is crucial before their application. In this context, a gene...
