[摘要] 对单跨砌体结构形式中小学教学楼的抗震性能进行了探讨。实例汁算分析结果表明：现行规范计算模型与实际结构不符，承重纵墙在地震作用下也要分担横向水平剪力，纵墙的P-⊿效应不能忽视。底层纵墙是结构抗倒塌的关键构件。针对教学楼建筑的实际施工现状，提出了再设计和改造对策。

Abstract: The seismic properties of single-span masonry structures used in school building were discussed. The numerical examples show that there were some different between calculate model based on current code and that of existing building. The bearing longitudinal wall should be taken into account against transverse earthquake action, and the P-⊿ effect couldn't be neglected. The bottom longitudinal wall was the key component during structure's resisting overturn, Some reliable reinforcement methods and applicable redesign measures were proposed according to practical construction situation of school building.
