| 摘 要： | 为了更好地了解不设横向加劲板箱形柱钢框架中节点的实际受力状态和破坏特征，建立了该节点的ANSYS有限元模型，对钢框架梁、柱翼缘板的受力、变形等进行了有限元分析，研究了该节点的破坏现象，分析了钢梁翼缘与箱形柱翼缘板域的应力分布。最后，将3个试件的试验分析和有限元分析进行了比较，以期对此类节点的分析和研究提供参考。

| Abstract: | To understand the actual stressful condition and destruction characteristics of the middle joints that connect the steel H beam of the steel frame and no stiffing plates provided in the box-column, this node finite element ANSYS model is es- tablished. The finite element analysis is applied on the column flange plate＇ s stress and deformation. This node destruction phenomenon is studied, and the steel girder flange and the cased column flange plate territory stress distribution are analyzed. Finally, the comparison of 3 tests sample＇ s tentative data and the finite element analysis is carried out, in order to provide the effective reference by the time to this kind of node＇ s analysis and the research. |
