5·12汶川地震高烈度区结构震害调查分析
|
摘要
结合现场调查结果,介绍并分析了汶川地震震中区附近建筑物震害现象。得到以下主要结论:一些按照国家现行(GB50011-2001)《建筑抗震设计规范》规定设计的建筑物的破坏低于预估破坏,真正做到了"大震不倒"。框架结构的破坏主要集中于梁柱结点区及构件上,整体倒塌的较少,砌体结构的破坏主要是倒塌、局部倒塌、墙体开裂。
Combined with the investigation results,the hazard of building around the epicenter region in Wenchuan Earthquake is introduced.Some conclusions are got: Some buildings designed conforming to the "Code for seismic design of buildings"(GB50011-2001) is better than what are anticipated.They did not collapse in severe earthquake.For the flame structure buildings,joints of beam and column and members failure are prevalent,and only few building totally collapses.For the masonry buildings,total collapse,local collapse and crack of wall are the main failure modes.
