摘要
定义了对结构各模态解耦的相关系数;提出了三维相关系数谱的概念,作出了离线计算的三维相关系数谱并探讨了其特性;在此基础上导出基于三维相关系数谱的多支承激励反应谱法。
The correlation coefficients of uncoupling modes are defined.The concept of 3-D spectrum of the correlation coefficients,which can be computed offline,is presented and discussed in this paper,and then the multi-supported response spectrum formula based on the 3-D spectrum of the correlation coefficients is derived.
