多层厂房结构易损性分析

【摘要】 本文针对厂房结构的一种多层厂房结构,进行相关资料收集,作为建立结构物分析模型之主要依据,并采用非线性动力分析和非线性静力分析来进行相关研究,分析出建立高科技厂房结构易损性曲线的参数,有助于日后评估类似建筑物在地震作用下,所造成的不同损伤程度与其概率,亦可依此做为未来评估厂房需要加固时的经济效益。更多还原

【Abstract】 Maximum story drift ratio is used as damage index in this study.In order to get the threshold of story drift ratio,we define four damage levels by capacity curve from pushover analysis and calculate maximum story drift ratio in corresponding damage level.Then,maximum story drift ratio under different intensity of earthquakes will be obtained by time-history analysis.After getting the above-mentioned data,we will establish the structural fragility curve with concepts of statistics.更多还原
