曲线梁桥预应力束摩阻损失计算

Frictional Loss Calculation of Prestressing Tendons in Curved Girder Bridge

以具有普遍性的曲线箱梁斜腹板内空间曲线预应力束为例，分析了空间曲线对预应力束摩阻损失的影响。并在实测基础上，对曲线梁桥中摩擦系数μ和偏差系数k的取值提出建议。

This paper proposes a general model of curved prestressing tendons in skew web of the curved box girder bridge,the effects of space curve on frictional loss have been analyzed. On the basis of experiment data,fictional coefficient μ and derivation k are suggested.
