摘　　要：本文采用有限元软件Abaqus,通过采用合理的材料本构关系,对波形钢腹板PC组合箱梁进行建模,建模过程中考虑了体外预应力索的滑移及连接部位的模拟。通过对试验梁的非线性有限元分析知,有限元模拟结果和试验结果吻合较好,因此,本文有限元模型的建立可供相关的研究提供参考。The finite element program Abaqus is adopted tor establishing finite model of box - girder with cotxugated steel webs which considering reasonable material constitutive. In addition, the simulation of connection portion and the slip between external prestressed tendons and the girder are taken into account in the model. The FEA results agree well with the testing results which can provide the relerenee for related research.
