As is suggested in the paper it is necessary to study the earthquake action for assessment of existing structures and the concept of assessment datum term and of assessment intensity is introduced.
本文阐述了研究在役结构评估用地震作用取值的必要性,并提出了评估基准期和评估烈度的概念;根据现有的烈度分布函数,建立了考虑不同评估基准期和不同地区地震危险性差异的地震烈度概率模型;按照等超越概率原则,提出了确定在役结构抗震评估用地震烈度的取值标准和方法,并给出了强度验算和变形验算地震作用参数的具体取值;对服役期间已遭遇过地震的结构,提出了烈度调整建议,为在役结构的抗震安全性评估提供了合理可行的荷载标准。
