| 摘 要： | ABAQUS作为一款大型有限元分析软件,其在工程结构研究领域得到了大量的应用。本文基于混凝土损伤塑形模型,采用该软件对两钢管混凝土轴压柱进行有限元模拟,讨论了钢管混凝土柱的三维非线性分析的建模方法和模型参数取值。研究了钢管混凝土柱的破坏特征、应力和应变特点等,并与试验结果对比,验证有限元模拟结果的可靠度。

| Abstract: | As a large-scale finite element analysis software,ABAQUS is widely applied in the field of engineering structural research.Based on plastic model of concrete damage in ABAQUS,the modeling method and parameter about 3-D nonlinear analysis of reinforced concrete column were discussed. Concrete-filled thin-walled steel tube column was simulated by the model. Through establishing reasonable numerical model the concrete-filled thin-walled steel column were analyzed,including the failure mode and the stress /strain characteristics. |
