摘要
通过模型试验 ,测定了张拉时 U形曲线预应力筋中有效应力沿预应力筋的分布以及混凝土中的有效应力的分布情况 ,并比较了在相同条件下 ,直线预应力筋与曲线预应力筋的孔道摩阻的不同分布规律 ,为更好地弄清
With the modeling testing, the effective stresses in the U curved prestressed reinforcements and the concrete have been determined. On the other hand, the different distributions of friction between the linear and the curved prestressed reinforcements have been compared. Moreover, an example about U curved prestressed reinforcement's friction has been provided.
