调谐质量阻尼器系统控制结构地震反应的若干问题

PROBLEMS IN SEISMIC RESPONSES OF STRUCTURES UNDER THE CONTROL OF TUNED MASS DAMPERS(TMD)

本文研究调谐质量阻尼器（ＴｕｎｅｄＭａｓｓＤａｍｐｅｒ，以下简称ＴＭＤ）用作抗震结构的防御体系时的一些问题，包括ＴＭＤ在结构上的最佳位置，ＴＭＤ频率的最佳值，ＴＭＤ对非调谐结构振型的影响和ＴＭＤ参数的灵敏度分析．这些问题的解决将为研究设置ＴＭＤ的结构的抗震设计方法提供理论依据．

This paper is concerned with problems in application of TMD to structural protection against seismic loads, including the optimum location of TMD in the structure and the optimal frequency of TMD, its effect on the untuned modes of the controlled structure and sensitivity analysis of the parameters of TMD. The main purpose of this paper is to make theoretical preparations for study of the design method of an aseismic structure with TMD.
