罕遇地震作用下SDOF结构位移响应的统计特性分析

Analysis of the Statistic Characteristics of Displacement Response of SDOF System under Rare Earthquakes

基于大量非线性时程算例分析结果和显著性分析 ,建立了多波输入下 SDOF结构平均最大位移响应与输入地震动拟位移谱、结构基本周期和屈服强度系数间的关系式 ,可为 DBD法中设计位移谱的确定提供参考。

Based on large quantity of the results of time history analysis and significance analysis, the relationship equation between the response of average maximum displacement to the displacement spectrum of input, structural period and yielding strength coefficient is established. It can serve as reference in the determination of the design displacement spectrum for DBD method.
