高位水箱改造成调谐液体阻尼器的设计与分析

The Design and Analysis on High Level Cistern to Tuned Liquid Dampers

随着钢结构与绿色建筑的快速发展,通常置于高层结构顶部的大容量水箱将导致钢结构的抗震性能严重降低。如果调整这些水箱尺寸,将其用作TLD设备,不仅可以降低水箱在受到横向荷载作用时对结构的影响,甚至可以缓解地震的影响。通过建立一个14层的高层钢结构建筑Abaqus模型,对TLD水箱在地震作用下的行为进行分析,根据不同参数的水箱的响应,得出了最优TLD水箱设计参数。

With the development of green architecture, a cistern with large capacity on high position usually results in a negative impact on structural seismic resistance, but if these cisterns can be modified to tuned liquid dampers (TLD). A high-rise steel structure with 14 stories with this kind of tank was analyzed in this paper to introduce the action about the cistern TLD. A finite element fluid-structure interaction model was established for Abaqus software and the effects of different parameters and the optimal parameters about the tank-TLD were studied.
