超大跨度钢筋混凝土框架结构裂缝控制研究

Research on the Crack Control of Super-Span Reinforced Concrete Frame Structures

基于混凝土结构跨度越大,由混凝土收缩和温度变化产生的结构约束应力也就越大,混凝土结构越容易出现裂缝这一现象,论文结合实际工程对超大跨度钢筋混凝土框架结构裂缝控制进行研究,阐述超大跨度钢筋混凝土框架结构裂缝的类型,分析裂缝控制技术,通过优化裂缝控制方案,加强关键技术环节管理,达到裂缝控制的目的。

Based on the phenomenon that the larger the span of the concrete structure,the greater the structural restraint stress caused by the shrinkage of the concrete and the temperature change,and the more likely the concrete structure will crack,this paper takes the actual project as an example,studies the crack control of super-span reinforced concrete frame structure,describes the crack types of super-span reinforced concrete frame structures,analyzes the crack control technology,by optimizing the crack control scheme and strengthening the management of key technical links,the crack control can be achieved.
