本文将联方型网壳结构的支座设置成弹性支座和弹性阻尼支座的方式对其隔震性能进行了分析。在罕遇地震作用下,分析比较了该结构在无控和有控状态下的动力响应,重点讨论了不同支座类型在地震波作用下的最大支座反力,节点位移和支座反力时程曲线。研究结果表明:弹性阻尼支座隔震效果明显。
In this paper, the anti-seismic performance of the joint-type reticulated shell bearing is set as the elastic support and the elastic damping support. Under the action of rare earthquakes, the dynamic response of the structure under uncontrolled and controlled conditions is analyzed and compared. The maximum bearing reaction force, joint displacement and bearing reaction force under different seismic loads are discussed. Curve. The results show that the isolation effect of the elastic damping bearing is obvious.
