砖混结构教学楼抗震加固方法

Anti-seismic and Strengthening Methods for Teaching Buildings of Brick-concrete Structure

2008年5月12日我国四川汶川发生了震惊世界的强烈地震,地震烈度达到11级,地震级别达到8.3级,地震造成69227人遇难,374643人受伤,17923人失踪,造成极为严重的人员伤害和经济损失,学校是重灾区,灾区校舍几乎无一幸免全部倒塌,造成学校师生极为严重的人员伤亡。随后党中央国务院决定实施校安工程,从2009年开始,对地震重点区域中小学校舍进行抗震加固。作者有幸参加几个校安工程的设计、施工,对砖混结构教学楼抗震加固设计、施工方法有一些经验分享,对以后砖混结构抗震加固有一些参考借鉴作用。

On May 12, 2008, a strong earthquake that struck the world happened in Wenchuan areas of Sichuan province,China. The earthquake intensity reached 11, and the earthquake level reached 8.3. The earthquake killed 69227 people, 374,43 people were injured, and 17923 people were missing. The earthquake resulted in extremely serious casualties and economic losses.The Central State Council decided to implement the school safety engineering. The author had a chance of participating in the design and construction of several schools and security projects. Hence, he would like to share the experiences with friends.
