摘　　要：通过数值模拟研究了地震作用下高层结构多个调谐质量阻尼器(MTMD)减震控制。根据实际工程,利用国际通用软件ETABS建立了结构三维有限元模型,进行了动力特性的分析,得到了结构的前几阶频率;根据不同场地类型,选取了4条典型的地震波;研究了调谐质量阻尼器(TMD)的参数选取和有限元的模拟;运用时程分析方法,分别研究了不同地震作用下高层结构有无控制下的反应。研究结果表明,MTMD对高层结构的减震控制效果明显,场地类型对减震控制效果有一定的影响。所获得的结果为高层结构减震控制设计提供参考和依据。In this paper, multiple tuned mass dampers seismic control for tall building structure under earthquake action is studied by numerical simulation. A three-dimensional finite element model of structure is established by ETABS based on practical engineering, and dynamic characteristics are analyzed, and first few natural vibration frequencies are obtained. Four typical seismic waves are selected based on different soil types. The parameters selection and finite element simulation of tuned mass damper are studied, respectively. Using time history analysis method, the responses of tall building structure with and without control under different seismic waves are investigated,respectively. The results show that the seismic control effect of MTMD for tall building structure is significant, and the soil type has a certain influence on the seismic control effect. The results obtained could provide reference and basis for seismic control design of tall building.
