摘   要：某学校教学楼地处8度抗震设防地区，由于现行抗震规范的变化，使原有建筑物的承载力及抗震构造均不满足规范要求。为保障该校舍在地震中的安全性，结合校舍结构的特点和加固需求，采用隔震技术对其进行加固处理。本文介绍了该项目的设计要点，并选取7条地震波进行非线性时程分析。计算结果表明，隔震结构的水平向减震系数小于0.4，降低了上部结构所受的地震作用，提高了工程结构的安全性；相关成果对中小学砌体结构校舍抗震加固具有重要参考价值。

Abstract: Due to the change of the current seismic code, the existing bearing capacity and aseismic construction cannot meet the specification requirements for the teaching building with 8-degree of earthquake fortification intensity. To ensure the safety of this teaching building in the earthquake, the characteristics and reinforcement demand of this teaching building structure was analyzed. Combined with the characteristics of school buildings, seismic isolation technique was used to reinforce this teaching building. The key points of the design for this reinforcement project is projected, in which seven seismic waves were selected to conducted nonlinear time-history analysis. The results showed that the earthquake effect on the upper structure was reduced for the horizontal seismic decrease coefficient less than 0.4, and hence the safety of this building structure was improved. The conclusion can provide the reference for seismic strengthening of masonry structure in primary and secondary schools.
