| 摘 要： | 无粘结筋的变形不符合平截面变形假定,因此由外荷载引起的应力计算比较复杂。从分析当前无粘结预应力技术现状入手对当前应用较多的无粘结预应力筋极限应力的多种求解方法进行了论述,并指出当前研究的现状和不足。

| Abstract: | The computation of stress resulted by external load is relatively complex because the deformation of unbonded prestressed strand cannot comply with the plane section assumption. IT presents the current status, and limitation and analyzes several computation approaches to ultimate stress of unbonded prestressed strand which is being used more widely. |

| Keywords: | unbonded prestressed concrete ultimate stress ultimate moment plane section assumption |
