预弯预应力混凝土受弯构件的挠度计算

Deflection of preflex prestressed concrete flexural members

基于６根模型试验梁和１根足尺实梁的试验结果，对预弯梁的挠度计算问题进行了探讨，给出了与现行桥规中挠度计算方法相一致的计算公式，以便于设计应用，计算结果与试验值吻合较好。

Based on the experimental results of six model beams and one full scale beam, the article makes an exploration of calculating of the deflection. For convenience of the design, a deflection formula coincident with the calculating method in present bridge design code is put forward, the calculating values agree well with the measured ones.
