摘 要:采用频域分析法推导了具有MTMD的MDOF结构受控振型广义坐标的频率响应方程,然后进行MTMD参数分析和设计,理论研究与计算结果表明只要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,同时具有造价低廉、维护简易的特点。

AbstractThe frequency-amplitude function for MDOF structures with MTMD is derived by using the frequency-area analysis method.Based on this function,the parameter analysis and design of MTMD are carried out.The numerical example showed that MTMD can effectively reduce the earthquake response if MTMD are accurately designed.
