摘要
在选取合理的材料本构模型、单元类型、接触设置和网格划分等关键参数的基础上,利用ABAQUS建立了圆钢管混凝土柱计算模型,对其进行了往复荷载下的有限元分析,得到了圆钢管混凝土柱的滞回曲线。将计算结果与试验结果进行对比得知两者的滞回曲线吻合较好,验证了模型的正确性,因此,提出一些关键参数选取的建议,可为相似问题的圆钢管混凝土柱有限元分析提供参考。
Based on the key parameters,selecting some rational material constitutive model,element type,contact setting and meshing,the calculation model of circular steel tubular column is established by using ABAQUS.Then running the model and obtaining the hysteresis curve of the concrete filled circular steel tubular column.Comparing the calculated results with the experimental results of the hysteresis curves,and both of the two are in good agreement,so the model is verified to be correct.Therefore,proposing some suggestions for key parameters,which can provide reference for the finite element analysis of concrete filled circular steel tubular columns with similar problems.
