| 摘 要： | 对内隔板式方钢管混凝土柱-钢梁栓焊连接节点提出了三种新型的梁端削弱方式,应用通用程序ANSYS对其进行三维非线性有限元分析,将计算结果与无削弱节点、狗骨式节点的分析结果进行对比。研究结果表明:翼缘开孔和翼缘腹板同时开孔的削弱方式能使梁端塑性铰明显外移,防止连接节点脆性破坏,可供实际工程设计参考。

| Abstract: | Three new forms of reducing beam section to square concrete-filled steel tubular column and steel beam connections with internal diaphragms are presented.These new joints are analyzed using FEM program-ANSYS,whose analytical results are compared with those of basic element and dog-bone connection.The results show that connection with opening on flange and connection with opening on flange-web can shift the plastic hinges away from the beam-column interface and prevent them from fragile damaging.So they can be served as reference for practical engineering design. |
