Abstract

Externally bonded fiber-reinforced polymer (FRP) reinforcement offers an attractive method for the strengthening of structures constructed of various materials. In such strengthened structures, the characteristics of FRP-to-parent material bonded joints play an important role. While extensive research has been carried out on the characteristics of FRP-to-concrete bonded joints, existing work on FRP-to-steel bonded joints is much more limited. In an FRP-to-steel bonded joint, the weak link is the epoxy adhesive, while in an FRP-to-concrete bonded joint, the concrete is the weak link. This paper examines, through a series of pull-off tests in which the FRP-to-steel interface is subjected to direct shear, the parameters that affect the behaviour of FRP-to-steel bonded joints. The test results are first presented and discussed. Based on these test results, the bond-slip relationship relating the interfacial shear stress to the interfacial slip is then investigated, leading to the development of the first ever bond-slip model for FRP-to-steel interfaces.
