| 摘 要： | 钢管混凝土柱与梁的节点构造和受力分析是钢管混凝土柱结构推广应用的关键技术所在。提出一种新型钢管混凝土柱环板节点,并利用有限元分析软件ANSYS,对该新型钢管混凝土柱环板节点进行空间非线性有限元分析,分析垂直对称荷载作用下该新型构造节点内的应力分布情况和内力传递机理,并与穿心节点和不穿心的环梁节点进行比较分析。分析结果表明,该新型钢管混凝土柱环板节点能有效地传递梁端内力,且构造简单,施工方便,可为钢管混凝土柱节点的设计提供参考和选择。

| Abstract: | The beam joints of CFST(concrete filled steel tube) column are 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,nonlinear 3D-FEM are presented in ANSYS for a new ring slab joint using the combined reinforced model and smeared cracking model.Under vertical and symmetrical loads,the stress distributions and the mechanism of internal force transmission in these joints are studied.The results show that the new ring slab joint can transfer the beam internal force effectively and could be a good choice for joint design. |
