汶川地震中小学砖混结构教学楼震害特征分析

Analysis of earthquake damage to masonry school buildings in Wenchuan earthquake

根据都江堰、彭州、崇州、绵竹四地中小学72幢砖混结构教学楼震害调查资料,按教学楼所在地区峰值加速度分类,分析了砖混结构教学楼的震害特征。震害统计数据表明带壁砖柱是此类结构的抗震薄弱环节。以此为基础,提出了砖混结构教学楼抗震设防的若干建议,可供此类结构教学楼设计和施工参考。

According to the investigation on the earthquake damage to 72 masonry school buildings in Doujianya, Pengzhou, Chungzhou, and Mianzhu, and the data of the earthquake damage are classified by the fortification in- tensity, the characteristics of the earthquake damage are analyzed, and the weakness of such building is the brick column associated with the wall . Based on the characteristics of the earthquake damage, some suggestions of seis- mic fortification of masonry school buildings are proposed for reference of seismic design and construction.
