Abstract ： To study the seismic mitigation performance of tuned liquid dampers（TLD）on concrete frame structures and the influence of their parameters on the damping effect，the YKJ software is used to model a six-story concrete frame structure. The ETABS finite element software is used for dynamic time-history analysis to study the seismic mitigation performance of TLD under diffrent seismic conditions and to compare the influence of different frequency ratios and mass ratios of TLD on the shock-absorbing effect. The results show that TLD can significantly improve the seismic capacity of concrete frame structures and reduce the seismic response of the structure. The maximum damping rate of the top displacement of the damping structure can reach 39.8% ：

0引言

抗震能力的有效手段之一，其基本原理是在结构中设置消能装置，将地震对结构输入的机械能通过消能装置转化为可均匀耗散的热能，结构的震动响应也因此减小。（剩余5770字）
