| 摘 要： | 在分析方钢管混凝土柱-H型钢梁框架3种刚接节点的构造形式和特点的基础上,提出了一种新型刚接节点———外肋环板节点。以外肋环板节点梁翼缘受拉模型为对象,分析了节点的受力传力机理,并基于屈服线理论,推导出了梁翼缘受拉模型的屈服承载力计算公式,为这种新型节点今后的研究和工程应用提供了依据。

| Abstract: | Vertical stiffener joint, a new type of rigid joint between concrete-filled steel square tubular column and H-steel beam, is proposed based on the analysis of construction and features of three types of rigid joints. Force transfer mechanism of the vertical stiffener joint model with only tensile beam flange is analyzed, and based on yield line theory, the formula for calculating the yield bearing capacity of the joint model is presented, which provides a basis for its further research and application in projects. |
