Unloading Behavior Study on FRP-Concrete Interface under an Exponential Softening Law

Abstract:

Loading behavior studies on FRP-concrete interface are refined enough. Because of the complexity of the problem, there exist relatively few unloading behavior studies. Occurrence mechanism of unloading needs to be clarified. Through a combination of theory and finite element method, this paper studied the unloading behavior involved in interfacial failure process under an exponential softening law, clarified when and where unloading occurred and estimated the effect of unloading.
