混凝土结构节点超筋危害的试验研究

Experiment About Over-reinforced Problem of Concrete Structure Node

混凝土结构的节点超筋现象严重,试验证明:由此会引起节点部位混凝土强度下降,对钢筋的锚固力随之下降;只有含钢量符合一定要求时,混凝土对钢筋的锚固力才得到保证。

In concrete structure,over-reinforced problem of node frequently appears.Experiments validate that the problem can descend concrete intensity and anchor force.Anchor force can be ensure when contain steel quantity.
