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分析,根据基础隔震结构的地震反应特点,给出了基础隔震结构水平地震作用改进算法。与基础隔震结构时程反应的对比分析表明,该改进算法既能较好地描述基础隔震结构水平地震作用的分布形态,又能满足结构层间剪力的要求,是合理有效的。
The prescription on vertical distribution form of horizontal earthquake action of base isolated structures in the codes of China and United States are expatiated, according to the earthquake response characters of base isolated structures, an improved method on horizontal earthquake action of base isolated structures is proposed, the results among the prescription in the codes, the improved method and the time history analysis are compared, it is shown that the results of the improved method not only depict the vertical distribution form very well but also satisfy the story shear of the structure, so the improved method is rational and available.
