摘要
为了研究中空钢管混凝土(HCFST)短柱的轴压性能,本文采用有限元软件ABAQUS对5根已有中空钢管混凝土短柱轴压试验进行数值模拟分析。通过选择合理的材料本构模型,建立该类短柱的有限元模型,获得轴压短柱的荷载-位移全过程曲线,与已有的试验结果进行对比,二者吻合良好。验证了本文有限元建模方法的合理性和可实施性,为中空钢管混凝土短柱在实际工程中的推广应用提供技术支撑。
To study the axial compression behavior of hollow concrete filled double steel tube composite short columns (HCFST), the finite element numerical simulation of 5 existing short columns under axial compression is carried out by ABAQUS in this paper. By choosing reasonable material constitutive model, the finite element model of this kind of short column is established, and the load-displacement curve of hollow concrete filled double steel tube composite short columns is obtained. Compared with the existing test results, the simulation data are in good agreement and thus the rationality and practicability of the finite element modeling method in this paper are verified. Lastly, it also lays a theoretical foundation for the popularization and application of hollow concrete filled steel tubular short columns in practical engineering.
