Limiting swing double-column type self-resetting energy dissipation high pier system with grading protection function
A limiting swing double-column type self-resetting energy dissipation high pier system with a grading protection function comprises a pile foundation and a bearing platform on the pile foundation. The two pier columns are vertically arranged on the two sides of the bearing platform respectively, and the lower ends of the pier columns are connected with the bearing platform through limiting swing hinges; the cover beam and the upper structure on the cover beam are arranged at the upper ends of the two pier columns, and the prestressed tendons penetrate through the upper structure, the cover beam, the pier columns, the limiting swing hinges and the bearing platform to anchor the five parts; and the energy dissipation mechanism is mounted between the two pier columns. According to the limiting swing double-column type self-resetting energy dissipation high pier system with the graded protection function, the typical problems that under the earthquake action, high pier column feet are prone to cracking, and the middle-upper portion is too large in deformation can be solved, and the design concepts that the high pier is not damaged in a small earthquake, can be replaced in a middle earthquake and can be repaired in a large earthquake are achieved.
一种具有分级防护的限位摇摆双柱式自复位耗能高墩体系，其包括：桩基及其上的承台；两墩柱，分别竖直设置于所述承台上两侧，且，墩柱下端与承台采用限位摇摆铰连接；盖梁及其上的上部结构，设置于所述两墩柱的上端，且，预应力筋贯穿上部结构、盖梁、墩柱、限位摇摆铰和承台，将五者锚固；消能机构，安装于两墩柱之间。本发明所述具有分级防护的限位摇摆双柱式自复位耗能高墩体系，可以兼顾解决地震作用下的高墩柱脚易开裂、中上部变形过大等典型问题，实现“小震不坏，中震可换，大震可修”的设计理念。
