摘要
在合理选择钢材和核心混凝土的本构关系模型的基础上,利用通用有限元软件ABAQUS对型钢-方钢管混凝土轴压荷载—变形关系曲线进行计算,计算曲线与试验曲线吻合较好,在此研究结果的基础上,可利用ABAQUS对型钢—方钢管混凝土轴压工作机理进行较为深入的研究。研究成果可为相关研究提供参考。
Based on rational constitutive model of steel and core concrete, load-deformation relationship curves of square steel tube filled with steel-reinforced concrete subjected to axial-compression are calculated by the ABAQUS software, and the calculated curves agree well with the experimental curves. Based on the conclusion, the behaviour of square steel tube filled with steel-reinforced concrete subjected to axial-compression can be studied deeply. The research may be referred for correlative research.
