摘要
本文在文献［１，４，５］的基础上，综合考虑了地震烈度的随机性，地震动的随机过程性及其动力效应，并系统地讨论了分别相应于设计基准期内的确定性和随机性地震烈度的结构随机地震作用的统计参数和概率分布，确定了各统计参数的具体取值，并给出了相应的概率分布，为结构抗震可靠度分析和设计提供了合理的随机地震作用标准．
In this paper based on Reference [1,4,5], the statistical parameters and probability distribution of structural ramdom earthquake action corresponding respntively to the determinate and the ramdom earthquake intensity are systematically discussed, the concrete values of statistical parameters are determined and the corresponding probability distribution is given. As a result, a resonable criterion of ramdom earthquake action is provided for the earthquake-resistant reliability analysis and the design of stuctures.
