【摘要】 2008年5月12日四川汶川发生8.0级地震,地震造成了大量建筑的倒塌和损坏,给人民的生命和财产带来了巨大的损失。该文选择四川地震主要灾区受损严重的错层砖混结构工程为研究对象,通过现场震害调查及原结构构件连接状况分析,建立符合实际的计算模型。应用结构空间有限元分析软件,采用振型分解反应谱法,按实际估计烈度进行抗震分析,其计算结果与实际震害基本吻合,由此分析错层砖混结构震害原因,总结了一些经验和教训。更多还原

【Abstract】 Wenchuan earthquake left numbers of buildings collapsed and countless losses of lives and properties.This paper analyses the damage mechanism of split-level brick-concrete structures in major disaster area of Wenchuan earthquake.Through on-site surveys and structural analysis,a realistic computational model is established.The calculated results are consistent with the actual earthquake damage states.Causes of the damage in split-level brick-concrete structure are discussed,and some experience and lessons are summarized.更多还原
