摘　　要：钢结构梁柱节点有多种形式,国内外学者研究多侧重在H形梁和H形柱的连接上,对于H形梁和矩形钢管柱(RHS柱)的连接研究则很少。由于矩形钢管柱是封闭截面,节点难以采用普通螺栓连接,采用对拉螺栓连接是这种节点的一种构造解决方案。基于理论模型、结合试验和有限元方法对矩形钢管柱与H形梁端板对拉螺栓连接的滞回性能进行研究,探讨该种连接形式的滞回特性。在试验滞回曲线的基础上,提出了节点的恢复力模型,该模型对钢框架的抗震设计具有较好的参考价值。There are various types of beam-to-column connections used in steel frames. H-shaped beam-to-column connections have been studied by a lot of researchers,while there is little information on the behavior of connections between rectangular hollow section ( RHS) columns and H-shaped beams. Since RHS column has a closed section,ordinary bolt connection is hardly used. Application of through-bolts is more feasible for connecting RHS columns and H-shaped beams. This paper presents experimental and analytical studies on the hysteretic performance of end plate connections between RHS columns and H-shaped beams using through-bolts. Based on the results from tests and finite element analysis,a restoring force model for beam-to-column connections was established. The proposed model provides a powerful tool for evaluating seismic analysis on steel frames.
