本文首先简要地综述了反应谱与竖向地震问题的若干情况,然后对收集到的203条美国的、40条国内的、14条日本的竖向加速度反应谱进行了综合的统计分析.通过竖向、水平向反应谱的全面比较,搞清了竖向反应谱的频谱特性,考察了震级、震源距、场地条件等几种因素对竖向反应谱值的影响,并提出了看法.统计所得的三种不同场地上的竖向标准反应谱可供工程抗震设计使用. 本文是在中国科学院工程力学研究所陈达生副研究员指导下完成的,并得到了王光远教授的关怀与指导.
In this paper, we first briefly review several aspects of the response spectrum and vertical seismic problems, and then perform a comprehensive statistical analysis of the vertical acceleration response spectra of the collected 203 US, 40 domestic, and 14 Japanese. After comprehensive comparison of the horizontal and horizontal response spectra, the spectral characteristics of the vertical response spectra were ascertained, and the influence of several factors such as magnitude, source distance, and site conditions on the vertical response spectra was investigated, and opinions were presented. The vertical standard response spectra on the three different sites can be used for seismic design of the project. This article was completed under the guidance of the researcher Chen Dasheng of the Institute of Engineering Mechanics, Chinese Academy of Sciences, and received the care and guidance of Professor Wang Guangyuan.
