摘　　要：TMD在实际工程结构中得到了广泛的运用和认同,为了进一步验证TMD的减震控制效果,进行了TMD-钢框架有限元模型的地震时程分析。首先分析了TMD的减震原理及其参数优化设计方法,根据有限元钢框架模型的动力特性设计了TMD减震装置的参数;然后利用有限元软件SAP2000对该TMD减震钢框架进行动反应有限元仿真分析。分析结果表明:该TMD减震装置具有显著的减震效果,能够有效地减小结构地震反应峰值。TMD has been gradually applied in the civil engineering. In order to verify the seismic reduction effect of TMD, a seismic response analysis of TMD - steel framework is conducted. Firstly, the parameters of the TMD were designed according to the structural parameters and dynamic property of the steel framework model; and then, the time-history analysis of the TMD - steel framework model would be carried out by using the finite element software SAP2000. The results showed that the TMD device could effectively reduce structural response and had a significant seismic reduction effect.
