| 摘 要： | 本文以强震记录地面水平向平均峰值为基本数据,研究了在无条件、分别或同时考虑房屋层数和场地类别的前提下,地震烈度与地震动峰值的对应关系.并依据统计结果讨论了峰值均值随烈度的变化规律,给出了把烈度转换成地面峰速度、峰加速度或设计地震反应谱的建议方案.最后还讨论了把设计地震反应谱转换成地震烈度的方法,给出了建议的转换方案.

| Abstract: | In this paper, relationships between seismic intensity and peak ground shaking are studied under no specific condition, or considering the number of storeys of the building and site category separately or in combination, based on the data of mean peak values of horizontal ground motion recorded during strong earthquakes. Then, according to statistical results, the variation of mean peak value with intensity rating is discussed, and schemes of peak ground velocity, peak gound acceleration or response spectrum of design earthquake converted from intensity rating are recommended. Finally, a methodology converting response spectrum of design earthquake to seismic intensity is also discussed; and a conversion scheme is recommended. |
