本文考虑了材料非线性、几何非线性和状态非线性，用通用有限元软件ANSYS对钢管混凝土柱钢梁加强环式节点的受力性能 进行了系统的研究，分析了加强环的形式、加强环的宽度、加强环的厚度、轴压比n( )以及混凝土和钢材等因素影响下的受力状态。本文深入 地分析了钢管混凝土柱钢梁连接节点在循环荷载作用下的受力性能，得出的结论为钢管混凝土结构加强环式连接节点的理论和设计方法的研究 应用、以及探索新型的节点形式提供了有价值的数据和参考依据。

Using the general finite element programming package of ANSYS10.0, this paper systematically analyzes the overall behaviors of the bolt and welt connections, synthetically considering nonlinear (material, geometry and contact) fact ors. In this paper, it simulates and analyzes the stress of 5 series sample considering the form of enforced loop plane, the breadth of enforced loop plane, the thickness of enforced loop plane, the ratio of pulldown and the effection of gradation of concrete and steel.The study analyzes the concrete filled steel-tubular column and steel beam connections’ load-bearing performance in a rather comprehensive and systematic way, and the conclusions can be useful for amending design code, guiding design of engineering, and provide good basis for further study of seismic-resistant behavior of other types of nodes.
