| 摘 要： | 将一种带有芯钢管的不连通钢管混凝土节点用于方钢管混凝土结构,验证了这种节点的可行性。选择材料本构关系和破坏准则,采用通用有限元工具ANSYS,建立三维有限元模型,对芯钢管中柱节点模型的外钢管应力、芯钢管应力、混凝土应力进行了分析。数值分析表明该节点用于方钢管混凝土柱与钢筋混凝土梁的节点,具有良好的性能且受力性能与在圆钢管混凝土结构中相似。

| Abstract: | The core steel tube applied to concrete filled square steel tubular structure and verify feasibility of this joint.Based on the appropriate material stress-strain relations and failure criterion,a 3-D nonlinear finite element method model was presented to analyze the mechanical properties of this joint with ANSYS.The numerical analyze results show that the core steel tube joint applied to concrete filled square steel tubular column and reinforced concrete beam have good mechanical property,and structure behaviors in concrete filled square steel tubular having a similar to this joint in CFST. |
