| Research Abstract |
The objective of this study is to develop a multi-layer smart anchor to optimize the seismic behavior of bridge piers after seismic strengthening. The structure and material properties of such an anchor has been clarified. The function of this anchor is to minimize the residual deformation of the structure and the damage of the surrounding material. A method where these functions are achieved by an anchor structure with an anchor steel bar having a multi-layer infill material attached was examined. As a result, it has been clear that an anchor with multi-layer infill properties having external layers with smaller strength and stiffness gives the optimum behavior.
