Abstract

One of main issues of the FRP-concrete composite member is shear connection between FRP and concrete in order to secure composite behavior of FRP and concrete. To solve this problem, perfobond rib FRP shear connector is introduced for the mechanical shear connection. In this study, experimental study was carried out on the perfobond rib FRP shear connectors in order to develop the effective details of perfobond rib FRP shear connectors. Pull-out test specimens were manufactured with FRP plate with holes embedded in concrete block. Main parameters considered in this study were diameter of holes, ratio of spacing between the centres of holes to the diameter of holes, and thickness of FRP plates. Test results are discussed according to above parameters compared with other empirical expressions for steel perfobond rib connector.
