[摘要] 汶川地震后，《建筑工程抗震设防分类标准》(GB50223-2004)进行了修订，将中小学校舍的抗震类别由原来的丙类提高到乙类。在这种背景下，通过对吉林省内部分中小学校舍近百栋房屋进行抗震排查鉴定工作，总结实践经验，查阅相关技术标准，认真研究规范条款，得出便于使用与理解掌握的抗震鉴定方法，对后续的中小学校舍抗震鉴定及加固改造工程具有实际意义。

Abstract: Afier WenChuan Earthquake, Code for classilz'cation of seismic protection of buildings( GB20223-2004)  was revised and anti-seismic classification of buildings of primary and secondary schools was upgraded from Group C to Group B.According to this background, hundreds of buildings of primary and secondary schools in Jilin Province were checked by earthquake-resistant evaluation and then some simplified earthquake-resistant evaluation methods based on relative technical standards and regulations are summed up. It was sure that those methods are absolutely significant to later earthquake-resistant evaluation for primary and secondary schools' buildings as well as reinforcement engineermg and modification works.
Keywords: masonry structure; earthquake-resistant evaluation; classification and determination; case history.
