摘　　要：根据基本假定并考虑材料特有的力学性能,以数值积分方法编制了预应力劲性混凝土梁的受力性能的计算程序,为验证程序的精度和可靠性,对文献预应力劲性混凝土梁的三分点加载试验进行了对比,数值计算出的荷载-挠度曲线同试验结果吻合良好;研究表明数值模拟方法为进一步预应力劲性混凝土构件设计理论的研究提供了一种可靠的方法和手段。According to basic assumption and the material properties of prestressed steel reinforced concrete girder, an analysis program is developed to reveal the mechanical behavior of flexural beams with the method of numerical integration. The moment-curvature relationships of the beams can be calculated with the program. A documented three-point bending test of prestressed steel reinforced concrete beams are presented to testify the reliability of this method. It is found that the loading- displacement relationships are in accordance with experimental results. Consequently, the numerical analysis provides a reliable reference and tool for the further study for design theory of PSRCB beams.
