Outline of Final Research Achievements

In this study, the post-tensioned connection between ductile cast iron plate with shear-key and concrete to apply the damper to a composite structures was adopted. First, cyclic shear tests of the proposed connection were carried out. As a result of the tests, shear strength of proposed connection is provided. Next, shear strength evaluation of proposed connection was considered. The shear strength of the specimens with shear-key was presented as the sum of friction resistance and bearing resistance by using a formula in the past. Then, finite element analysis that reproduced the component tests was carried out. As a result of the analysis, the principal stress of concrete was confirmed. Finally, the design of the damper connection to a concrete composite structure by using the proposed connection method was shown.
