摘要
在确定了不锈钢与核心混凝土的材料本构模型、单元类型以及界面接触模型的基础上,根据构件的几何和材料非线性,建立了圆不锈钢管混凝土轴压构件的有限元模型.算例分析结果表明,有限元计算和试验结果总体上吻合良好.利用有限元模型,比较了不锈钢管混凝土和普通钢管混凝土轴压构件的荷载-变形关系曲线.
A nonlinear finite element （FE） model was developed to simulate circular concrete-filled stainless steel tubular columns under axial compression, based on the nonlinear material behaviour, nonlinear geometric behaviour and bonding-slip between stainless steel tube and concrete core. The result showed the test result could fit FE results in terms of load versus deformation response. Using the FE model, the load versus deformation curve of the concrete filled stainless steel tubular column was compared with that of the conventional concrete filled carbon steel tubular column.
