摘要
时程分析法中选择输入地震波的基本要求通常是使所选波的反应谱与设计反应谱在统计意义上相一致，实践中对此要求却常有不同的理解和处理方法。本文以结构底部剪力、顶点位移和最大层间位移为主要反应统计量，对比分析几种选波方案，提出基于规范设计反应谱平台段和结构基本自振周期段的两频率段控制的选波方案。
There are many ways to satisfy a basic request to select inputting waves for a time-history analysis. The response spectrum of the selected earthquake waves has to be accordance with the designed response spectrum in the statistical sense. Several methods to select earthquake waves commonly used in practice are discussed. A new method (Plan C in the text) for selecting the inputting waves is proposed in the paper. The new method controls two frequency domains, which are corresponding to the flat range of the designed response spectrum and the natural period of structure.
