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。 A middle school teaching building in Shanghai was built in 1983, the original design by 6 degrees seismic fortification, there is obviously not in line with the existing seismic code. In order to ensure the safe use of school premises, the survey of raw materials, on-site inspection and seismic performance evaluation of structures are carried out, and the corresponding reinforcement plan is put forward according to the assessment results. The reinforced structure basically reached the key fortification-type seismic fortification standards, the structural integrity and bearing capacity has been significantly improved, thereby improving the safety of the structure.
