摘　　要：本文论述了水平地震作用下,并联隔震层产生水平位移过程中,橡胶隔震支座与摩擦滑移隔震支座之间将产生竖向力转移的自适应保护特性和计算方法。工程实例表明,考虑竖向荷载转移时,隔震层的侧移将有所下降,使体系具有自适应保护功能。The vertical force will transfer between rubber bearing and sliding isolated bearing under the horizontal earthquake when the parallel isolation layer creates the horizontal displacement. This paper discusses the adaptive protection characteristic of parallel seismic isolation system and calculation method. The engineering example shows that the horizontal displacement of isolation layer will decrease when the vertical force transfer is considered. The system has self-adjustable function.
