Push-out tests were conducted to investigate the shear performance of FRP perfobond shear connectors. Shear failure was observed on the ribs of connectors at ultimate. Based on test results, the FRP perfobond connectors showed relatively high shear capacity and could be applied to the FRP-concrete composite deck. Then the simply supported FRP-concrete composite deck with FRP perfobond shear connectors was tested under monotonic load. The load versus mid-span deflection response of composite deck behaved linearly up to the ultimate load. Shear failure occurred on the webs of FRP deck near the upper flange, while the FRP perfobond shear connectors remained intact without any damage. The measured maximum mid-span deflection was 25.4 mm, corresponding to 1/63 of the simply supported span, which demonstrated the large deformability of FRP-concrete composite deck.
