| 摘 要： | 假设ＴＭＤ对被控结构的影响归结为增加调谐结构振型的阻尼；提出了结构等效阻尼比的概念和计算方法。推荐了以应谱修正的一个公式；并把在已知结构上ＴＭＤ系统的优化设计叙述为约束规划问题，在此基础上我出了ＴＭＤ系统系统的抗设计步骤，并以一个数字例子说明其应用。

| Abstract: | In this paper , the assumption is concluded after analyses of the ef- fect of a TMD on it'scontrolled structure that the effect of the TMD on the structure results in an increase in the damping of the tuned structure mode with the TMD. The concept and the calculation method of the equivalent damping ratio of a structure are proposed and a formula for revision of the code spectrum is recommended . The optimization of TMD on a known structure is formulated as a constrained minimization problem. The design steps of TMD - structure systems subjected to seismic excitations and code provisions are mentioned and a numerical example of structure design is used in illustration of their applications. |
