摘　　要：根据预应力简支钢箱梁的受力特性,考虑预应力索与钢箱梁的相互作用,建立了有限元计算模型,有限元计算值与实测值吻合较好。基于有限元分析软件ANSYS,对所建模型进行了全过程仿真计算,并对梁的荷载—位移曲线,跨中截面应力以及跨中截面应变进行了较为详细的分析。According to the mechanical character of simply supported steel box girder with prestressed tendons, and considering the interaction of tendons and girder, the finite element model is established. The calculation results of model were found to be in good agreement with the experimental data. Based on finite element analysis software ANSYS, the full course simulation was conducted, and the model is adopted to analyse loading - displacement curve, variation of stress at mid - span and variation of strain at mid - span.
