Abstract:

During construction， a wide range of cracks appeared in the middle beam slab of a five-layer framework structure building， which badly affected the safety of the building. Based on the testing data and check results of the structure obtained on the scene， the cause of beam slab crack was analyzed systematically. Three kinds of reinforcement plans were put forward. The first scheme has been described in detail， which could be used as reference for other similar projects.

Key words: frame structure, component crack, structure analysis, reinforcement

摘要：

某五层框架结构实验实训楼在建设过程中梁板构件出现大范围的开裂现象，严重影响了结构安全及正常使用性功能，基于现场检测数据和结构验算情况对该建筑物开裂构件的裂缝原因进行了系统的分析，对开裂构件提出了三种加固处理方案，并对第一种方案进行了详细叙述，其加固处理方案可供其他类似工程做参考。
