摘要
以某中学框架实验楼为例,介绍了框架结构加固鉴定的一般程序,运用现行规范和PKPM对原结构进行了周期和振型分析。分析表明,该实验楼在建筑类别、轴压比和局部配筋上存在不足。提出了具体的加固建议。
This paper takes the lab building of a middle school as an example,and introduces the general procedure of frame structure identification and reinforcement.And the cycles and vibration models of original structures are analyzed with current criterions and PKPM.Analysis shows that there are some defects of construction type,axial-load ratio and local reinforcement existing in this building.And consolidation suggestions are put forward in detail.
