基于ABAQUS的HCFST中短柱力学性能分析

Mechanical behavior analysis of HCFST columns based on ABAQUS

基于有限元软件ABAQUS,对圆钢管高强混凝土轴压中短柱力学性能进行非线性有限元分析。采用混凝土塑性损伤模型,讨论了圆钢管高强混凝土中短柱三维非线性分析的建模方法和模型参数取值,研究了其破坏特征,应力和应变特点等。与实验结果对比,验证了有限元模拟结果的可靠性。

Based on finite element software ABAQUS, this paper analyzed the axial compression performance of high -strength concrete filled steel tube（HCFST） column.By using plastic model of concrete damage in ABAQUS , the modeling method and parameter about3D nonlinear analysis of HCFST were discussed ;the failure mode and the stresss/train characteristics were studied.Compared with the experi-mental results, the reliability of the finite element simulation results was proved .
