| 摘 要： | 在选择了合理的钢材和混凝土的本构关系模型的基础上，利用通用有限元软件ABAQUS对钢管混凝土柱一钢筋混凝土环梁中柱节点的受力性能进行了较为深入的研究。研究结果表明，钢管混凝土柱-钢筋混凝土环粱节点可以实现“强节点弱构件”的抗震设计要求。基于分析结果，对钢管混凝土柱-混凝土环梁节点的设计提出了建议：按图集进行设计时，环梁上、下主筋截面面积可适当减少；环梁的配箍率至少不小于与之相接的框架梁中的配箍最大值。研究成果可为相关研究和工程实践提供参考。

| Abstract: | Based on rational constitutive model of steel and concrete, behaviour of the inner joint of concrete filled steel tube column-RC beam joint are analyzed by the ABAQUS software. The results show that the joint of concrete filled steel tube column-RC beam joint can achieves the request of strong joint and weak member in aseismatic design. Based on the research conclusion in this paper, some design suggestion of the joint was propos- ed, the suggestion is that the area of longitudinal steel may be reduced and ... |
