本文对粘钢加固的钢筋混凝土受扭构件进行了多种粘钢方案的试验研究。对构件加固后的应力应变状态、破坏机理及如何确定有效粘钢部位进行了初步探讨,得到了提高受扭构件强度的合理粘钢方案和可供加固设计参考的大量数据。
In this paper, a series of experiments on the bonded steel reinforced concrete reinforced concrete torsion members were carried out. A preliminary discussion was made on the stress-strain state, failure mechanism and how to determine the effective steel-bonding location after the reinforcement of the components. A reasonable steel-bonding scheme for improving the strength of torsion members and a large amount of data for reinforcement design were obtained.
