| 摘 要： | 在建筑结构中,一般粘滞阻尼器均布置在层间,但在有些情况下较小的层间位移差在一定程度上制约了阻尼器性能的充分发挥。系统回顾了为解决这一问题,目前最新的一些解决方案:改进层间阻尼器的连接方式,如基于连杆结构、杠杆原理与齿轮机构的位移放大系统,及大对角支撑;新型结构保护系统,如利用结构构件竖向振动位移及框架核心筒结构的加强层阻尼系统等,并重点分析了加强层阻尼系统。

| Abstract: | The dampers are generally placed between the adjacent stories in building structures,but in some applications the relative small displacement has restricted the performance of dampers.To solve this problem,lots of countermeasures have been proposed,which are reviewed in detail.One is the improvement of the connecting method,such as the displacement amplification system based on linkage,lever mechanisms as well as gear mechanisms,and big diagonal braces.There are new types of structural protection systems,su... |
