Prestressing tendons in continuous beams of internal span is made of three parabolas, and the equivalent loads on the internal span caused by stretching the prestressing tendons is made of three parts of vertical uniform loads with opposite directions. There are some difficulties in calculating the internal forces as so many parts of loads. Through the comparison of the moments at the fixed ends caused by real prestressing tendons profile and by assumed profile, we propose a simplied formula of equivalent loads for calculating the moments at the fixed ends caused by streching the real prestressing tendons, and the calculation process of the midspan moments caused by equivalent loads for stretching the real prestressing tendons is dicussed. The thought and method can be applied in engineering designs.

连续式内跨梁的预应力筋由三段抛物线组成 ,张拉预应力筋引起内跨的等效荷载也由方向相反的三区段竖向均布荷载组成 ,由于荷载区段较多 ,给在等效荷载下内力的计算带来了不少困难。本文通过对实际预应力筋线型与假想预应力筋线型分别对应的等效荷载作用下固端弯矩的比较 ,得出了用于计算张拉实际预应力筋引起固端弯矩的等效荷载简化计算公式 ,同时给出了计算张拉实配预应力筋所引起的等效荷载作用下跨中弯矩的过程。本文的思路和方法可用于工程设计。

对于单跨预应力混凝土框架梁和多跨预应力混凝土框架的内跨梁,通过位移法证明了用一定矢高的单波抛物线代替实际预应力筋进行次弯矩的计算,方法简单,结果准确。对于多跨预应力混凝土框架的边跨梁,由于预应力筋布置形式与内跨不同,采用与单跨梁相同的简化方法进行计算,结果可能会有较大误差,建议按实际预应力筋形状计算。
