输电塔－线耦联体系地震反应分析方法（Ⅱ）：纵向

本文通过一座三层的耗能－隔震柔性底层钢管混凝土结构模型和一座三层普通钢筋混凝上结构模型的振动台实验，着重研究了耗能－隔震柔性底层钢管混凝上结构的抗震性能和减震效果，并与普通的钢筋混凝土结构的实验进行了分析比较，研究了两种结构体系在地震作用下的耗能分布和地震累积损伤情况。实验结果表明，耗能－隔震柔性底层能够有效地吸收地震输入的大部分能量，防止和减小了上部结构的地震破坏．文中还讨论了耗能－隔震柔性底层结构中钢管混凝土柱与橡胶隔震器之间的轴力分配以及在水平变形下的稳定性问题．

SHAKING TABLE TESTING AND DAMAGE ANALYSIS FOR CFST STRUCTURES WITH FLEXIBLE FIRST STOREY OF ENERGY DISSIPATION-ISOLATION

n this study, the shaking table testing was carried out for a RC structures and a concrete filled steel tube (CFST) structures with flexible first story of energy dissipation-isolation. The aseismic ability between CFST and RC structures was compared. The two kinds of structural system energy dissipation distribution and accumulated damage analysis were also included in this paper. The testing results showed that most input energy of earthquake was absorbed by the flexible first story of CFST structures, which prevented the seismic damage of the upper structure.
