摘要
介绍在输电塔基础处设置SMA弹簧-轴承滚动支座的地震响应分析,对滚动支座采用SMA弹簧作为复位和耗能元件,获得了较好的隔震效果,时程分析结果表明输电塔的构件内力、上拔下压力及层间位移显著降低,结构变形接近于整体平动。
The paper introduces that the transition tower which is installed a SMA spring-beating isolator is analysis in the SIMULINK environment, The rolling isolator uses a SMA spring as a resting and energy dissipation element and obtains a good isolation results. The transition tower on the base isolation system is analysis by the time-history method under the El-centro wave,the result shows that component internal force, overturn force,story drift decreases effectively.
