［摘要］5·12汶川特大地震使四川綿竹市教育系統(tǒng)遭受了巨大沖擊，通過詳細(xì)分析砌體結(jié)構(gòu)、傳統(tǒng)磚木結(jié)構(gòu)和框架結(jié)構(gòu)的中小學(xué)校舍的震害特征及原因，為重建提出以下建議：通過合理的措施提高結(jié)構(gòu)整體性；附屬結(jié)構(gòu)與主體結(jié)構(gòu)之間應(yīng)有可靠的連接；確保砌體結(jié)構(gòu)教學(xué)樓縱向窗間墻的承載能力；在抗震設(shè)防地區(qū)的教學(xué)樓應(yīng)該優(yōu)先選用框架結(jié)構(gòu)；良好的施工質(zhì)量是結(jié)構(gòu)抗震性能的重要保證。

Abstract:Education system of Mianzhu city suffered severe damage during Wenchuan Earthquake. In order to give some reasonable advice to the reconstruction of school buildings, the performance of masonry structures, masonry structures with timber roof and RC frame structures during the earthquake were presented. Many structural or non-tructural deficiencies were highlighted by the earthquake, which include poor integrity, weak connection between components, lack of strength of walls between windows in masonry structure, poor construction quality. The RC frame structure should be considered as the main structure for the school buildings in priority. Good construction quality is the important access to the good anti-eismic capacity of buildings.
Keywords:Wenchuan Earthquake; school buildings; damage; seismic design
