【摘要】 上海市某中学教学楼建于1983年,原设计按6度抗震设防,存在明显不符合现行抗震规范的问题。为保证校舍继续安全使用,进行原始资料调查、现场检测及结构抗震性能评定,根据评定结果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,结构整体性及承载力得到显著提高,从而改善了结构的安全状况。更多还原

【Abstract】 A comprehensive seismic evaluation for a middle school teaching building in Shanghai was made.The building,completed in 1983,was designed with an earthquake fortification intensity of 6-degree,which cannot meet the demand for the current code.To insure the safety of the structure,initial data were investigated,on-site test was performed,and then seismic performance evaluation was made.According to the evaluation,it was put forward corresponding reinforcement measures,and the structure achieved the seismic fortification criteria.Which not only significantly enhanced the structural integrity and load-carrying capacity,but also improved the safety of the structure.更多还原
