摘　　要：某教学楼经抗震鉴定为A类砌体结构建筑,其抗震能力不满足抗震鉴定要求,因此需要对原结构进行整体加固。本工程采取隔震技术后,只需对墙体采用双面钢筋网水泥砂浆面层加固即可。采用ETABS软件对结构在设防地震、罕遇地震下的结构反应进行计算分析,结果表明隔震结构减震效果良好,满足规范要求。A teaching building in the eighth degree area is identified as a class A masonry structure by seismic evaluation.Its seismic capacity does not meet the requirements of seismic evaluation,so it is necessary to strengthen the original structure.After the isolation technology is adopted in this project,it is only necessary to strengthen the wall with double-sided steel mesh cement mortar surface layer.ETABS software was used to calculate and analyze the structural response of the structure under fortification earthquake and rare earthquake.The results show that the isolation structure has good damping effect and meets the specification requirements.
