摘　　要：利用调谐液体阻尼器(Tuned Liquid Damper,TLD)对高层建筑地震反应进行振动控制研究。根据Fujino等提出的矩形TLD减振基本原理,建立了TLD中液体动水压力的控制方程,并采用有限差分法对矩形浅水TLD液体动水压力进行数值模拟,然后根据1栋91.0 m的高层建筑实际情况提出几种TLD设计方案,分别对其进行TLD-结构地震作用下的动力分析,比较几种方案的减振效果,确定最佳方案及具体的结构振动控制设计。结果表明,TLD系统对高层建筑地震作用下的加速度反应和位移反应均具有比较好的控制效果。The vibration control was presented for the high-rise building using tuned liquid damper （TLD） to reduce seismic response. Authors first formulated the governing equation of the movement of the water in the TLD based on the basic principle of the vibration suppression of the structure with shallow water rectangular TLD presented by Fujino. The finite difference method was used to simulate the dynamic liquid pressure. According to the present situation in the example of a 91.0 m high-rise building, authors then proposed several kinds of TLD design plans according to the conditions of the project, chosed the best one according to the dynamic response analysis of the TLD-structure system. The results show that the TLD system can efficiently reduce the responses of acceleration and displacement for high-rise building under the condition of seismic.
