汶川地震的震害引发的对建筑结构体系的思考

汶川地震造成了巨大的人员伤亡和经济损失。文章概述了建筑物破坏情况，由此总结出砖混结构的房屋损毁最为严重，而钢筋混凝土框架结构也有较严重破坏。通过历史震害记录表明，钢结构房屋的震害较钢筋混凝土结构房屋的震害要小，钢结构具有优秀的抗震性能。建议应大力推广钢结构体系在我国的应用，特别是在学校、医院等公共建筑及办公楼、住宅中的应用。

The Thinking of Building Structure System from the Wenchuan Earthquake

Wenchuan earthquake caused large number of casualties and economic loss. The article has summed up the destroying condition of buildings, from this summarizes that brick- concrete structuro, building had been destroyed most seriously,and reinforced concrete frame structure building also had been destroyed comparatively gravely. The records of history earthquake harms indicate that the earthquake harms of steel structure building are smaller than reinforced concrete structure building, steel structure has the excellent seismic resistance function. It is suggested to improve the application of steel structures system in our country ,especially for public buildings such as schools , hospitals.and office buildings, residences.
