摘要
本文建立了基于低周疲劳试验的抗震结构倒塌指标。通过18,000多个倒塌反应算倒,分析了结构倒塌反应的影响因素。运用正交设计和方差分析方法,得到了这些影响因素的显著性水平和显著性顺序。根据分析结果,将结构划分为强结构、中强结构和弱结构三种类型,并提出了相应的倒塌验算方法。
Based on low-cycle fatigue tests,the collapse index of seismic structures is presented here. Through a vast amount of calculating,the factors which affect collapse earthquake responses of structures are analysed. Applying variance analysis and orthogonality design methods,the dominance level and order of the factors are gotten. According to the analysis results, seismic structures are classified into three types: strong, moderate and weak. Finally, the relevant design methods are proposed.
