摘要
隔震技术采用一系列的措施,使隔震支座和消能装置吸收地震时地面输入建筑物的能量,减小建筑物在地震时产生的振动,有效保护建筑结构及内部设施。依托福建省防震减灾指挥中心大厦的隔震结构进行研究,利用PKPM系列软件及具有强大非线性分析功能的ETABS软件,采用弹塑性时程分析法对隔震结构与非隔震结构的地震反应进行对比分析,总结分析隔震结构的地震反应规律。分析结果表明,隔震结构的消能作用显著。
with a series of measures of base-isolation technology,base isolation bearing and energy-dissipation devices can absorb energy input during an earthquake so that vibration minimization is achieved to make sure the effective protection of building structure and inner establishments.This paper focuses on the shock insulation structure of the central building of Fujian earthquake disaster mitigation.With the help of a series of PKPM software and ETABS software,the earthquake response of isolated structure and the normal structure is compared and analyzed with elastic time-history analyzing method and therefore patterns of response are reached.The results of analysis and actual measurement prove the effectiveness of energy-dissipation in shock insulation structure.
