摘　　要：为研究锈蚀对于钢-混凝土组合梁受负弯矩的力学性能影响,采用ABAQUS有限元分析软件建立7个组合梁模型。通过对7个模型施加负弯矩荷载,研究锈蚀对组合梁的力学性能影响规律。分析结果表明:随着栓钉锈蚀率的增加,组合梁刚度出现明显降低;钢梁-混凝土之间的滑移增大,组合梁极限承载力呈现下降趋势,但下降程度较少。Seven steel-concrete composite beam finite element models are build to study the effect of the corrosion on the mechanical behavior of composite beams , hogging moment was applied on 7 uncorroded and corroded composite beam models. Results indicate that the stiffness of composite beams under hogging moment decreases when the stud corrosion rate increases. The bond-slip between the steel and concrete increase with the increased stud corrosion rate. The ultimate strength of steel-concrete composite beams slightly decreases with the increased stud corrosion rate.
