摘要
本文通过对广东省近400个项目的地震安全性评价结果进行分析,发现在相同的地震基本烈度或相同的场地类别条件下,地震影响系数最大值αmax、特征周期Tg和衰减指数γ的取值范围较大。在对其进行分析研究的基础上,提出等效特征周期的方法,使一般的设计软件能方便使用地震安全性评价结果。
Based on an investigation through the evaluation results of seismic safety of about 400 projects in Guangdong province. It is found that the variable range of maximum value of seismic influence factor αmax characteristic period Tg and attenuation exponent γ is wide under the condition of the same basal seismic intensity or the same site group. The method of equivalent characteristic period is suggested in this article, thus to enable an easy application of evaluation results of seismic safety.
