摘要
汶川大地震发生后,大量房屋建筑整体性倒塌,造成了严重的人员伤亡和经济损失。根据现场实际震害调查,总结和反思了若干经验教训,其中对建筑结构的整体性抗震和构造进行了分析,包括设防水准、概念设计、选型布局、结构整体性、结构刚度、强柱弱梁、构造措施、非结构部件、抗震缺陷、病态抗震结构等等。汶川地震震害也证明了建筑结构整体性抗震和构造的重要性。
After the Wenchuan great earthquake,many buildings collapsed and the great earthquake caused huge casualty and serious economic loss.In this paper,based upon post earthquake field work and investigation,several earthquake damage lessons are drawn,especially about the aralysis of structural integrity and construction measures,which include seismic protection level,conceptual design,structural types and systems,structural integrity,structural stiffness,strong column-weak beam,building construction,non-structural member,aseismic defect,ill-conditioned aseismic structure,and so on.
