| 摘 要： | 介绍了基础隔震结构能量设计方法原理。运用有限元分析软件ANSYS建立了5层3跨框架结构模型,对比分析了基础固定结构、基础隔震结构和粘滞耗能组合隔震结构地震反应。结果表明,基础隔震结构的地震反应显著小于基础固定结构,隔震结构层间位移集中于隔震层。在隔震层加设粘滞阻尼装置后,上部结构减震效果与未加设阻尼器隔震结构相近,而隔震层位移显著减小。

| Abstract: | Energy design principle of structural base isolation is presented. lhe model oi a 5-story and 3-span frame structure is built by means of analysis software ANSYS. Then time history analysis of structures with base isolation, isolation and viscous dampers, or without isolation, is performed under various earthquake records with different intensities. The comparison analysis of the structures is put forward and the results show that the seismic response can be mitigated significantly with base isolation. Furthermore, similar effectiveness of seismic reduction at superstructure and considerable mitigation of displacement at isolation layer can be obtained with viscous dampers at base isolation. |
