摘要
采用ABAQUS对一个钢管混凝土核心柱节点试件建立数值模型进行模拟分析,并与试验结果对比。从材料本构的定义、单元的选择、模型的划分、边界条件和荷载的施加等方面,较为系统的阐述了节点的有限元模拟,通过模拟计算得到的节点荷载位移曲线和破坏模式,与试验结果吻合较好。
An finite element simulation for a connection between steel reinforced concrete beam and concrete-filled steel tubular core columns was conducted by finite element software ABAQUS,and the results for the simulation and tests are compared. The finite element simulation of the node is explained systematically from the definition of material constitutive,the selection of the unit,the partition of the model,the boundary condition and the application of load. The load-displacement curves and failure modes of the node by simulation are in good agreement with the experimental results.
