| 摘 要： | 本文研究高层建筑利用调液阻尼器（ＴＬＤ）减小地震反应的方法。首先探讨了激励频率比、调谐频率比对减震效果的影响。在此基础上建立了具有不同ＴＬＤ设置方式的高层建筑体系的学模型和运动方程，首次提出了利用多个ＴＬＤ减小高层建筑多个振型的方法。最后通过数值算例验证了本文方法的有效性。

| Abstract: | This paper is focused on the study of the tuned liquid damper (TLD) used as the passive control device to reduce the structural responses to earthquake ground motion. First of all, the effects of ratios of the excited frequency and tuned frequency on the reduction of seismic responses of structures are investigated. And then, the mechanical models and the equations of motion for the systems of tall buildings with the differently installed ways of TLDs are established based on the single degree of freedom system.The approach for reducing the multi modal responses of tall buildings with the multi-TLDs is here presented. Finally,the approach in this paper is proved effective through the numericalcal culations. |
