Abstract

Cyclic behaviour of the FRP-to-steel bonded interfaces is a key issue to be addressed in modelling the long-term performance of FRP-to-steel bonded joints. However, compared to extensive experimental and theoretical study on the bond-slip behaviour between two adherents, either FRP-to-steel or FRP-to-concrete under monotonic loading, so far only few research have been carried out on the cyclic behaviour of such bonded joints. This paper presents a new bond-slip model to model the behaviour of FRP-to-steel bonded joints under quasi-static cyclic loading. In addition, an analytical model to model the load-displacement behaviour and interfacial shear stress distributions is also presented. The results from the proposed model and the results from another existing model are compared with the experimental results from two FRP-to-steel bonded joints tests under cyclic loading. Results from the proposed model show a better agreement with the experimental load-displacement behaviour, shear stress distribution and the bond-slip behaviour.
