摘　　要：在TMD系统的质量、阻尼和总刚度均保持不变的情况下,拟定3种不同的TMD系统设置方案,并从地震荷载激励方面来研究调频质量阻尼器对超高层结构的振动控制。通过对3种方案的结构模型进行模态分析和动力时程反应分析,得出在地震荷载激励下控制前后的结构响应,并比较了3种方案下TMD的控制差异,选择出最优方案。此外从能量的角度出发,分析了TMD耗散地震能的能力,并确定出在减少地震输入能及增大阻尼耗能作为控制目标时的最优方案。With the quality, damp, total stiffness of TMD system remain unchanged, this paper proposed three different TMD system setup programs, researching the tuned mass damper to the vibration control of mega-high-rise buildings from the aspects of seismic loads incentive. Through the programg structural model of this three modals a- nalysis and the dynamic time history response analysis, getting out the structure response of seismic loads incentive, before and after. To comparison the differences in control of TMD with the three plans, choose the best plan. Moreover, from the energy power of view, to analyse of the seismic energy dissipation capacity of TMD, to determine that the best plan which reduces seismic input energy and increase as damping energy as objectives of control at the end.
