摘要
在选择合理的钢材和核心混凝土本构关系模型的基础上,利用通用有限元软件ABAQUS对矩形钢管混凝土T型受压节点荷载-变形关系曲线进行计算,计算曲线与试验曲线基本吻合,并对矩形钢管混凝土T型受压节点荷载-变形关系进行全过程分析。在此基础上,采用ABAQUS对矩形钢管混凝土T型受压节点的工作机理进行更为深入的研究。
Based on rational constitutive model of steel and core concrete, load-deformation relationship curves of concrete filled rectangular steel tube T-shaped joint subjected to compression are calculated by the ABAQUS software, and the calculated curves agree generally with the experimental ones, then analysis of load-deformation relationship curves of concrete filled rectangular steel tube T-shaped joint subjected to compression is carried out. Based on the research conclusion in this paper, the behaviour of concrete filled rectangular steel tube T-shaped joint subjected to compression can be studied deeply.
