| 摘 要： | 目前，底部剪力法是各国计算水平地震作用的基本方法，应用该方法时需要使用各自国家的抗震设计反应谱。本文汇总了中、美、欧抗震设计规范的反应谱和底部剪力法，在相同重现期和场地条件的基础上，对比了不同烈度下3本规范反应谱的异同，并通过算例对比了分别采用3本规范的底部剪力法算出的不同设防烈度下同一结构的底部地震剪力和层间地震剪力。对比结果表明，3本规范的反应谱和底部剪力法在本质上是相同的，只在表达形式和参数设置上存在差异。

| Abstract: | Base shear force method is the basic for calculating the horizontal earthquake action in different countries in the world, and the seismic design response spectrum of each country is needed when using this method. This paper summarizes base shear force method in Chinese, the U.S.A. and European seismic codes. On the basis of the same recurrence period and the same site conditions, the differences and similarities of the three standard response spectra were compared under different intensities. Taking a case study as an example, the earthquake shear forces at the bottom and between the layers are contrasted by using base shear force method in different seismic codes. Our results show that the essence of base shear force method of the three seismic codes from three different countries is similar, while the expression form and parameter settings are different. |
