结构地震破坏影响因素与结构分类

Dominate character of factors affecting earthquake damage of structures

考虑结构低周疲劳特性的破坏准则 ,采用大样本量地震动输入 ,对结构地震破坏的诸影响因素进行分析研究 ,通过数值试验和方差分析方法 ,确定这些影响因素的显著性水平和显著性顺序 .根据分析结果将结构分类 。

Based on the earthquake damage criteria of structures that reflecting the low cycle fatigue characteristics of structures, a vast amount of non linear earthquake response analysis of structures is carried out and the factors that affect the response and damage of structutes are discussed in detail.Applying variance analysis and orthogonality design methods, the dominance level and order of the factors are acquired.According to the analysis, earthquake resistant structures are classified as three kinds.Lastly, design method of every kind of structure is presented.
