| 摘 要： | 并联基础隔震结构是由橡胶隔震支座与摩擦滑移隔震支座并联组合形成的隔震结构，结构中两种型式的隔震支座相互取长补短，可以有效地降低隔震结构的造价。由于两种隔震支座竖向刚度的不同，在地震作用下，隔震层发生水平位移时，将引起轴力由橡胶隔震支座向摩擦滑移支座转移，这种轴力的重新分配对整个系统是有利的，使系统可以根据水平地震作用的大小来改变系统本身的耗能能力。根据合理的假设，推导了该种结构隔震支座的轴力随水平位移的变化关系，得出摩擦滑移隔震支座的力与位移曲线呈蝶形的结论。

| Abstract: | The layer of parallel isolation structure is combined with sliding isolated bearings and rubber bearings. With the rubber bearings and the sliding isolation bearings learning from other’s strong points to offset their weakness, the parallel isolation structure is an economic system. Because the vertical stiffness of two kinds of bearings in parallel isolation structure is different, their axial forces will shift each other when the displacement of isolation layer increases under earthquake. The transfer is a self-adjustable performance of the system ,and this redistribution of axial forces is favorable to the whole system. And can make the system change its energy dissipation capacity. A according to reasonable hypothesis, the axial forces-displacement behavior of the sliding isolated bearings is deduced and the shape of their relation curve is papilionaceous, when the transfer force is considered. |
