Floor Response Spectrum Analysis of Controlled Interconnected Structure System

应用等效最优控制方法对互连结构体系被动控制器的刚度参数和阻尼参数同时进行了优化,并在此基础上,建立了安装有次结构时有控互连结构体系的动力学模型,研究了控制器参数优化设计结果对次结构楼层反应谱的影响,得出一些有参考价值的结论.

Two-connected structure system was designed to cooperate to resistant the earthquake. The connecting parameters of this new combined system and the floor response spectrum analysis are interesting for researchers. In this paper, the equivalent optimal control method is adopted to optimize the connecting parameters including both stiffness and damping of passive controllers. On the basis of it,the mathematic model and the floor response spectrum are analyzed by considering a secondary structure which is installed on one floor and coupled with the combined system. Numerical example shows some valuable results by comparing two cases of controlled system and non controlled system.
