“…However, to the best of our knowledge, few researches have been reported for FRP perfobond shear connectors. Based on previous work of Nam et al [4], FRP perfobond shear connectors exhibited the advantages of high shear capacity and convenient construction. In 2012, Xue [5] performed an experimental study on shear behavior of epoxy adhesive and FRP perfobond connectors, and the results showed that shear capacity of FRP perfobond connectors increased slightly relative to the epoxy adhesive while relative slip at the interface increased rapidly as the applied load increased, indicating the lower shear stiffness of FRP perfobond connectors.…”

ABSTRACT:In this paper, four FRP-concrete composite slabs and one FRP profile without concrete slabs were tested through two types of shear connectors including FRP perfobond shear connectors and epoxy adhesive under positive and negative loads. For composite specimens under negative loads, flexural buckling failure was observed on the top flanges of FRP profiles; while shear buckling failure occurred on the webs of FRP profiles for those under positive loads. At the ultimate state, the measured mid-span deflection was more than 1/90 of the span for all specimens. Besides, it was noticed that relative slip at the interface between FRP profiles and concrete slabs for composite specimens with epoxy adhesive was lower than that for specimens with FRP perfobond shear connectors. Based on the Tsai-Wu criterion, the Tsai-Wu index of the two failure modes was calculated for composite slabs when buckling failure occurred.
