高层建筑结构扭转耦合地震反应阻尼器控制试验研究

Experiment on Damper Control for Torsion Coupled Seismic Responses of Multistory Building Structures

运用最近提出的阻尼筒控制系统对高层建筑结构扭转耦合地震反应阻尼器控制进行振动台模型试验研究。首先简要介绍了阻尼筒控制系统的构造和控制原理及其阻尼特性的测试试验，继而在振动台上对一三层钢框架模型进行了模型试验研究。试验结果表明，通过对该三层框架模型施加阻尼筒控制，其顶层扭转角位移反应得到了显著的降低，从而验证了阻尼筒控制系统不仅能有效地控制高层建筑结构的水平地震反应，而且能有效地控制高层建筑结构的扭转耦合地震反应，因而在工程中具有广阔的应用前景。

An experimental research on damper control of torsion coupled seismic responses of multistory building structures is performed on shaking table using the tubular damping controller(TDC) proposed recently. The models of TDC and a 3-story steel frame are briefly described and its dynamic properties are tested. The dynamic responses of the frame model with or without TDC control are tested on the shaking table, and the results show that the torsion angle responses at the top floor of the frame model are significantly decreased in the case of TDC control. This proves that TDC is able to suppress not only the horizontal but also the torsion coupled seismic responses of multistory building structures, and it has vast prospect in actual engineering application.
