被动控制和主动控制系统都有各自不可克服的缺点，而采用混合控制系统则可充分利用二者的优点、克服二者的缺点，从而拓宽控制系统的应用范围。基于这种思想，本文对在砌体结构上安置橡胶垫隔震支座和作动器的混合控制系统进行了研究。分析中，考虑了在强震作用下结构及隔震层的非线性特性，其中上部结构按三线性恢复力模型考虑，而橡胶垫隔震层按双线性恢复力模型考虑。
Passive control and active control systems have their own insurmountable shortcomings. However, the hybrid control system can make full use of the advantages of both to overcome their shortcomings and broaden the application range of the control system. Based on this idea, this paper studies the hybrid control system with rubber pad isolation bearings and actuators placed on the masonry structure. In the analysis, the nonlinear characteristics of the structure and the isolation layer under the action of strong earthquakes are considered. The superstructure is considered according to the trilinear restoring force model, while the rubber lining is considered according to the bilinear restoring force model.
