汶川地震对建筑结构设计的启示

Some Thought on Building Structure Inspired from Wenchuan Earthquake

汶川大地震造成了大量房屋建筑的破坏。本文通过对钢筋混凝土结构和砌体结构的震害研究、非结构构件的震害分析以及典型震害进行的调查归类分析,探讨了此次地震对建筑结构抗震设计的启示,总结了经验并给出了以下相关的建议:(1)适当提高抗震设防标准。(2)房屋建筑设计要更好实现"强柱弱梁"机制;改进加强楼梯间设计;进一步研究非结构构件与主体结构的连接。(3)进一步推广隔震技术。

Wenchnan Ms8.0 earthquake has resulted great damage of mass buildings. Through analysis on earthquake damage of reinforced concrete, bricks or stones, and non-structural buildings, we summarize some lessons learnt from this earthquake, and point out some suggestions on anti-seismic building design in the future as follows： 1） increasing anti-earthquake standard of building at some extent; 2） calling for ＂stronger column than beam＂ -type structure; 3） extending earthquake isolation technology.
