摘要
采用频域分析法考虑ＴＭＤ在多自由度结构中的位置，推导了具有ＭＴＭＤ的多自由度结构受控振型 广义坐标的频率响应方程，据此进行了ＭＴＭＤ的参数优化和设计．算例表明，只要ＭＴＭＤ设计正确，它 就可以有效地减小结构在地震作用下的动力响应。
Taking the installation of TMD into account, this paper has derived frequency-amplitude function for MDOF structures with MTMD using the frequency-domain analysis method. Based on this function, the parameter optimization and .design of MTMD are carried out. The numerical ex- ample showed that MTMD could effectively reduce the earthquake response if MTMD are accurately designed.
