地震烈度与竖向地震动峰值的转换

本文基于笔者采用过的同时考虑房屋层数和场地类别时烈度到水平向地面峰值转换的基本思路,统计研究了烈度与竖向地面峰值的对应关系,明确指出了不同烈度下竖向与水平向峰值的比值应该是有所不同的,并给出了建议的比值,给果可供一般工程抗震设计参考使用。

CONVERSION OF SEISMIC INTENSITY INTO VERTICAL PEAK GROUND VALUE

In this paper, the corresponding relation between seismic intensity and vertical peak ground value is statistically studied on the scheme of converting intensity into horizontal peak ground shaking in consideration of building story number and site category at the same time. It is clearly pointed out that, the ratio of vertical peak value to horizontal one should be different for different intensities. The recommended ratios have been presented in the paper. The obtained results can be used as reference for anti-earthquake design of ordinary structures.
