摘　　要：为解决有限元软件ABAQUS分析型钢-钢管混凝土力学性能遇到的常见问题,对模型的建立、混凝土塑形损伤本构模型、钢材与混凝土之间的接触等问题进行了探讨,并利用有限元软件对型钢-圆钢管混凝土的短柱轴压、长柱失稳和构件的抗弯力学性能进行了算例验证,所得结果与试验结果吻合良好。研究结果表明:建立的力学模型和探讨的相关问题用来分析型钢-圆钢管混凝土的力学性能是合理的,且收敛性较好。研究中探讨的关键方法可为研究人员分析其它钢-混组合结构或构件提供借鉴,以及为设计人员设计构件提供参考。In order to solve the common problems occurred in analyzing the circular steel tube filled with steel-reinforced concrete（ STSRC） by using the finite element software ABAQUS,the issues of three-dimensional entity model,concrete plastic damage constitutive model,aw well as the contact between steel and concrete were discussed.Then,the axial load of the short columns,the stability failure of long columns and the bending behaviors of the components were calculated by ABAQUS,and the results obtained agreed well with those of the experiments. This indicates that the mechanical models and the relevant technical analysis are applicable at analyzing the mechanical behaviors of STSRC with good convergence. The key methods in this research can provide a reference for the researchers and designers in analyzing and designing other steel-concrete composite structures or components.
