汶川地震典型民居震害特征分析
|
摘要
汶川"5.12"Ms8.0级特大地震造成了巨大的经济损失和人员伤亡。大量的民居房屋遭到了破坏。针对汶川地震灾区典型民居结构——砖混结构和底框架结构,通过震害描述介绍了其破坏形式,并按构件从基础到屋面依次分析了震害特征及结构破坏机理。最后对民居房屋建筑的建设提出了设计与施工方面的建议。
Wenchuan Ms8.0 earthquake on May 12,2008 caused great economic losses and casualties.The earthquake disaster reflects the lack of appropriate seismic measures resulting in insufficient seismic capacity of residential housings in the disaster area.The typical residential structures in Wenchuan earthquake disaster area include brick and concrete structure and bottom frame structure.This paper summarizes the damage characteristics of the typical residential structures.The damage mechanism is analyzed according to the phenomenon of earthquake damage from the base to the roof.In the end,advice on the design and construction of rural residential housing is proposed.
