| 摘 要： | 钢管混凝土柱与梁的节点构造和受力分析是发展组合结构体系的关键技术。利用有限元分析软件AN-SYS,对采用不同构造的典型钢管混凝土柱与现浇钢筋混凝土梁的单梁穿心节点进行了空间非线性有限元分析。分析了垂直对称荷载作用下,采用不同构造的穿心节点内的应力分布情况和内力传递机理,根据分析结果提出了该类型节点的构造设计建议。

| Abstract: | The beam joints of CFST (concrete filled steel tube) is the key technique for the application of CFST structure. The types of joint are multiform. Due to the importance of the constitution and performance under loads of beam joints of CFST column, a series of nonlinear 3D-FEM are presented in ANSYS for typical single beam joint with different constitution using the combined reinforced model and smeared cracking model. Under vertical and symmetrical load case the stress distributions and the mechanism of internal force transmission in those joints are studied. According to the analyses, some advices were put forward for reference to improve the joint design. |
