摘要
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。
Active control system and passive control system have disadvantages severally, but hybrid control system can make use of their advantages and overcome their disadvantages, and then extends the range of control system. According to this idea, hybrid control system consisted of rubber－ bearing isolation and actuator is studied in this thesis. The hybrid control system is put on the brick structure. During the course of analysis, the nonlinear property of structure and isolation layer is considered. The structure is a three－ linear hysteric restoring force model, but the rubber－ bearing is two－ linear restoring force.
