Development of Multi-layer Smart Anchor

本研究旨在研制一种多层式智慧型锚，以改善桥梁桥墩在抗震加固后的抗震性能。这种锚的结构和材料特性已被阐明。这种锚的作用是使结构的残余变形和周围材料的损伤最小化。研究了一种方法，其中通过具有附接有多层填充材料的锚钢筋的锚结构来实现这些功能。结果，已经清楚的是，具有多层填充特性的锚具有更小强度和刚度的外层，给出了最佳性能。

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.
