摘　　要：本文对叠层橡胶支座基础隔震建筑的混合振动控制问题进行了研究。利用控制律设计的变结构趋近律方法， 给出了相应的闭环控制律表示式。算例分析结果表明： 变结构趋近律控制方法能有效地减小隔震层及上部结构各楼层的地震反应，By using the reaching law method of the variable structure system of sliding model control theory, two kinds of close loop feedback controllers are presented for building structures equipped with base isolation hybrid protective system The compound equation of motion of the above mentioned hybrid control structure system, which is suitable for numerical analysis, has been constructed The simulation results indicate that the hybrid control methods presented in this paper are quite effective

关 键 词：基础隔震 混合控制 变结构趋近律法 建筑
