［摘要］针对贯通隔板相关参数对方钢管柱焊接工字形钢梁钢框架节点抗震性能的影响，设计了4个隔板贯通式节点试件，对其进行了低周反复循环荷载作用下滞回性能的试验研究。试验表明，该类型节点具有较好的延性和承载力，强度退化和刚度退化稳定。隔板的厚度对节点承载力有明显影响，厚度越大，承载力越高；在一定范围内，隔板的平面尺寸越大，越能将应力有效分散到更大区域，对承载力有一定贡献。

Abstract: In order to study the impacts of the continuous diaphragms on the seismic behavior of steel frame joint with square steel tube column and H-shaped steel beam, four diaphragmthrough joint specimens were tested under low cyclic loads to investigate the hysteretic behavior. The experiment results show that the ductility and the bearing capacity are sufficient and the strength degradation is stable as well as the stiffness degradation.Diaphragm thickness has a major influence on the bearing capacity of the joint and the bearing capacity is in proportion to the thickness of the diaphragm. In a certain range, the diaphragms with bigger planar dimension can effectively distribute the stress to a wider area, which contributes to the bearing capacity.

Keywords: diaphragm-through joint; square steel tube; hysteretic behavior; experimental study
