摘要
为研究钢管约束的钢管混凝土柱轴压性能,文中基于试验基础,结合材料本构关系并考虑了混凝土的损伤,利用ABAQUS软件对试验中的构件进行了有限元计算。有限元模拟所得承载力曲线和试验所得相符,验证了有限元模型及材料属性的正确性。最后对此类构件进行了参数分析,研究了钢管约束不同的参数对轴压性能的影响,为此类构件试验和工程应用提供参考。
In order to study the axial compression performance of concrete-filled steel tube columns confined by steel pipes, based on the experimental basis, combine with the material constitutive relationship and the damage of the concrete was considered, and the finite element calculation of the members in the experiment was carried out using ABAQUS software. The bearing capacity curve obtained by finite element simulation is consistent with the test results, which verifies the correctness of the finite element model and material properties. Finally, the parameter analysis of this type of component is carried out, and the influence of different parameters of the steel pipe restraint on the axial compression performance is studied. This kind of component test and engineering application provide reference.
