| 摘 要： | 本文通过对带内隔板的十字形连接节点的拉伸试验，研究了方钢管混凝土柱与钢梁连接的结构性能。借助于在柱翼缘、梁翼缘和内隔板上的应变测量，分析了连接区域的应力传递机制。基于屈服线理论，并考虑连接区域的应变性能，提出了方钢管混凝土柱与钢梁连接的承载力方程，可供制订规范和工程设计参考

| Abstract: | Structural behaviors of the connections between concrete filled square tubular column and steel beam have been studied by the tensile tests of cruciform joint models with inner diaphragm. The stress trsanfer mechanism of the connection is analyzed from the strain measurements at the column flange, beam flange and inner diaphragm. The equations for yield and ultimate capacity of the connection have been proposed based on the yield line theory taking the strain behavior of the connections into consideration. |
