Analysis of seismic mitigation performance of concrete frame structure with tuned liquid dampers

WANG Dunqiang，ZHENG Yu （School of Civil Engineering，Shandong Jianzhu University，Jinan 25O1O1，China）

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% ：

Key words ： tuned liquid damper；concrete frame structure； shock-absorbing effect； finite element； timehistory analysis

0引言

抗震能力的有效手段之一，其基本原理是在結(jié)構(gòu)中設(shè)置消能裝置，將地震對(duì)結(jié)構(gòu)輸入的機(jī)械能通過消能裝置轉(zhuǎn)化為可均勻耗散的熱能，結(jié)構(gòu)的震動(dòng)響應(yīng)也因此減小。（剩余5770字）
