摘　　要：上海市某中学主体教学楼为砖混结构,建于1985年,1991年对实验楼及通廊进行扩建,原设计抗震设防分类为丙类,6度抗震设防。通过对教学楼进行全面结构检测和抗震鉴定,评定结果表明,原房屋依据现行规范构造柱设置不足、砂浆强度较低、多数纵向墙段抗震及受压承载力不足,整体抗震性能不满足现行抗震规范的相关规定。针对以上问题,提出相应的加固方案,加固后的结构基本达到重点设防类抗震设防标准,后续使用年限为40年。The main teaching building of a middle school in Shanghai is the masonry structure, founded in 1985, following the expansion of the laboratory building and the corridor in 1991. The original design of earthquake-proofing of the original design was classified as Class C, with an earthquake fortification intensity of 6 degree. A comprehensive structural seismic evaluation of teaching building was done based on current norms. The evaluation results showed that the number of constructional columns was inadequate, mortar strength was much lower than the normal value, most of the vertical wails＇ antiseism and compressive bearing capacity were insufficient, thus, the overall seismic performance could not meet the requirements of current seismic code regulations. In accordance with the results of the evaluation, the strengthening method was put forward to achieve fortification class seismic standards and follow-up using period of 40 years for the teaching building.
