摘　　要：本文作者针对既有文献在利用 TMD原理求加层减震房屋隔震层最优参数时只考虑了原结构顶层位移反应而忽略了加层结构的地震反应的事实 ,以原结构和加层结构在地震作用下的响应最小为目标函数 ,结合数值搜索进行了最优参数估计的推导 ,并与以往文献的结果进行了比较 ,结果表明 ,本文的结果能达到整体最优的目的。In many papers there only define the earthquake response of existing building as objective function when seeking the optimal parameter of isolation layer in adding story and seismic decrease.It is irrational because the earthquake response of adding structure is neglected.Based on TMD theory and combining with the method of value seeking,the optimal parameter calculation method is derived when considering objective function as the earthquake response of the existing building and the adding structure.By comparing with the result of paper[1],it is proved the globe optimum result can be obtained using the method in this paper.
