In this paper, three dimensional FEM analysis is conducted referring the experimental results about the shear strength distributional property of perfobond strip having plural perforations. Results of the FEM analysis are also compared with the experimental ones. In this analysis, the analytical conditions are refined focusing on the stress-strain relation of concrete, boundary condition of the steel plate and the surrounding concrete, treatment of the reinforcing bars and so on and most suitable case is found to reproduce the experimental results averagely. Moreover, the shear force-relative slip relation, the shear strength distributional property along the longitudinal perforation and the strain behavior of the steel plate by the FEM analysis are investigated and these results show almost similar tendency as the experimental ones.
