【摘要】 通过在"北川废墟"的实地考察,分别从地质灾害、结构工程、市政工程等三个方面详细记录了地震灾害对城市毁灭性的影响,并着重阐述了不同结构形式的破坏特征,简要分析了建筑物破坏以及倒塌的原因.最后,说明了我国现行《建筑抗震设计规范》(GB 20011—2001)的合理性、适用性以及存在的问题,可为建筑结构抗震设计与理论完善和修正提供参考.更多还原

【Abstract】 Based on the field survey to the Beichuan Seismic Ruins,several aspects including geologic hazard,structural engineering collapse and municipal engineering damage are detail recorded.The failure characters of the different structural types are expounded comprehensively;and then the reasons of seismic damages are analyzed respectively;the rationality and the applicability of the current code for seismic design are proved,the problems are also purposed according to the damage characters analysis.This paper provides reference for verification to seismic design and theoretical analysis.更多还原
