隔震技术在高层建筑中的应用初探

A preliminary exploration into the application of seismic isolation technique in high-rise buildings

高层建筑固有的自振周期较长,从反应谱曲线观察,采用隔震技术继续延长周期似乎减震作用不明显。针对这个问题,以某高层结构隔震设计为例,通过合理调控隔震层的刚度等方法,达到了满意的隔震效果,印证了隔震技术在高层建筑中应用的可行性。

As high-rise buildings have a relatively longer fundamental period of vibration,using seismic isolation technique to further extend that period seems to result in less significant effect in reducing seismic vibrations,as indicated by response spectrum curves. To address this problem,a case of seismic isolation design for a high-rise structure is presented in this paper,in which approaches like reasonably adjusting the stiffness of isolation layer are employed. The effect of seismic isolation is found to be satisfactory,confirming the feasibility of applying seismic isolation technique in high-rise buildings.
