In this research, I investigated experimentally the mechanism of the perfobond strip with or without the penetrating reinforcement in case of resisting the shear force in detail by using the original push-out specimen. I also clarified the shear force distribution of the perfobond strips which are arranged longitudinally along the steel plate. Furthermore, the design formula is proposed for evaluating the shear resistance of the perfobond strip taking into account the proportion of the concreteblock as well as the perforation size and the concrete compressive strength.
