摘要

对中国和美国相关规范中基础隔震结构水平地震作用的分布规律进行了阐述和分析,并将其与基础隔震结构时程地震反应分析的结果进行了对比。分析表明,基础隔震结构水平地震作用接近于均匀分布,采用倒三角形分布是不恰当的;同时,在确定基础隔震结构水平地震作用分布规律时,应考虑上部结构动力特性的影响。
The prescription on vertical distribution form of horizontal earthquake action of base isolation structures in the codes of China and United States are expatiated,the results between the prescription in the codes and the time history analysis are compared,it is shown that the horizontal earthquake action are close to uniform distribution,the inverted triangular distribution is irrelevancy,and as to ascertain the vertical distribution form of horizontal earthquake action the influence of the dynamic characteristic of the supper-structures should be considered.
