The object of this study is to estimate shear strength of Perfobond Rib shear connectors were used by direct shear stress. To estimate shear strength, Perfobond Rib shear connector experiments were fabricated with four variables which are existence or nonexistence hole, number of holes, distance of hole and number of reinforcing bars and Push-out Tests were carried out on them. After experiments, mechanism of Perfobond Rib shear connector was examined. The result of experiments, primary factors which influence direct shear strength are point bearing capacity of Perfobond Rib shear connector, effect of concrete dowels and effect of reinforcing bars. Lastly, based on primary facors, direct shear strength formula was proposed.
