中印(尼)规范的强震区高桩码头地震反应谱差异

Seismic response spectrum difference of high-pile wharf in macroseismic area between Chinese and Indonesia specification

针对中国与印尼抗震设计规范的差异,将设计地震、场地类别、设计加速度反应谱等参数进行对比。结果表明,强震区印尼规范加速度反应谱曲线水平段比中国规范的长,加速度反应谱曲线峰值比中国规范最大抗震设防烈度对应的峰值大。基于某高桩码头工程,利用ANSYS软件,采用振型分解反应谱法,分析同一场地土采用不同规范的地震效应的差异,为类似的抗震设计提供参考。

In view of the differences between Chinese and Indonesia seismic design specification,we compare the parameters of design earthquake,site classification and design acceleration response spectrum.The results show that the horizontal length of Indonesia specification acceleration response spectrum curve is longer than that of Chinese specification in macroseismic area,and the peak value of acceleration response spectrum curve is larger than that of maximum seismic fortification intensity in Chinese specification.Basing on a high-pile wharf project,we analyze the differences of seismic effect in different specifications of the same site soil by ANSYS software and response spectrum method of mode decomposition,which can provide references for the similar projects.
