摘　　要：为了对某钢框架进行减震控制,本文利用该钢框架的结构参数和动力特性,设计了FPS型TMD减震装置。然后用有限元软件SAP2000对该减震钢框架结构进行非线性动反应时程分析。分析结果表明:该装置具有显著的减震效果,能够有效地减小主结构的地震反应。为下一步的振动台试验和FPS型TMD减震装置的参数优化提供依据和参考。In order to control seismic response of a steel framework, a FPS Type TMD designed according to the structural parameters and dynamic property. And non-linear Time-History analysis is carried out for the seismic system by finite element software SAP2000. The results show that the TMD device could effectively reduce the structural response and have a significant seismic reduction effect. It could provide the basis and reference for the shaking table test and parameters optimized.
