Integrating with relevant literature report about the stress performance of steel-concrete composite box beam,in order to study its overall stress process,using Ansys finite element analysis software,the paper carries out spatial finite element analysis by considering the influence of material nonlinear upon steel-concrete composite box beam.The analysis results is identical to experimental results.%结合钢箱—混凝土组合梁受力性能的相关文献报道,为研究其受力全过程,利用Ansys有限元分析软件,考虑了材料非线性对钢箱—混凝土组合梁受力行为进行了空间有限元分析,分析结果与试验结果吻合良好。
