某高层建筑混凝土结构的开裂与对策

Cracking and countermeasures of concrete structures in a high-rise building

混凝土结构的裂缝控制是关系到结构物能否满足正常使用要求的重要课题。本文讨论了某高层建筑的混凝土长墙及核心筒周围楼板开裂原因 ,并分别提出了控制裂缝的对策 ,为类似的混凝土结构施工提供了指导性建议。

? Crack control in concrete structmes is one of the important topics that impair structures' serviceability. This paper analyses the reason of cracking for dle long concrete wall and the concrete slab around the core cylinder in a high rise building.Then this paper distributed the countermeasures of crack control for two project examples. This provides the guidance suggestion for construction of similar concrete sonctures. 〔
