Failure Analysis on Cracking in Cast-in-Place RC Floors and Reinforcement Measures in a Housing Project

为提高建筑结构的整体性及抗震性能,民用建筑普遍应用了现浇钢筋混凝土楼板,但现浇楼板开裂问题比较突出,直接影响到建筑质量.结合工程实例分析了现浇楼板发生开裂事故的原因,并对碳纤维布加固措施进行了阐述.

To upgrade the integrality and aseismic behaviour of architectural structure, the cast-in-place RC floor is widely used in civilian construction. However, the in-situ floor cracking is rather prominent, which directly spoils the building quality. Based on an engineering case, this paper analyses the causes of in-situ floor cracking and explains the carbon-fiber-cloth reinforcing measures.
