( China Railway Fifth Survey and Design Institute Group Co., Ltd., Beijing 102600, China)Abstract: A lead core rubber bearing isolations structure was simulated and analyzed by finite element software. The calculation cases were mainly divided into considering the soil-structure interaction and not considering the soil-structure interaction. The results show that after considering the soil-structure interaction, the displacement time-history curve of base-isolation structure is gentle. The interlayer displacement amplitude is reduced more than that of not considering the soil-structure interaction.
Keywords: lead core rubber bearing; base isolation; soil-structure interaction
