【摘要】 面对数千条的强震记录如何快速、合理的选出3~5条记录用于结构抗震分析,已越来越成为困扰设计人员的新问题。依场地类别和峰值加速度进行选波的方法被提出,该法可以大大减少反应谱的拟合工作量。利用IDARC-2D进行了结构在罕遇地震下的弹塑性时程分析,计算结果显示,方法有一定的工程实用价值。更多还原

【Abstract】 As the strong ground motions increase,how to select design ground motions from thousands of ground motion records has become a serious problem to a designer.Site condition and peak ground acceleration were selected for the two criteria to select strong ground motions,which can greatly reduce the work of fitting the design response spectrum.IDARC-2D was used to conduct the elasto-plastic time history analysis.The example confirmed the accuracy of the method put forward in this paper,the method can be applied to the actual structural design.更多还原
