摘　　要：为了解决钢结构建筑在构件的运输以及施工过程中存在的诸多问题,设计开发了一种全部连接均采用螺栓的新型装配式钢结构柱梁连接节点。针对此类节点进行了低周循环加载试验,通过对试验现象的总结及构件破坏特性的分析,对试验数据进行回归计算后建立了新型外环板式节点的骨架曲线模型和恢复力模型。研究结果表明:所提出的装配式方钢管柱-H型钢梁的三折线恢复力模型,可以作为此种类型的钢结构装配式柱梁连接节点的地震响应分析以及设计计算提供理论及实际应用的参考。For the sake of resolve many issues consist in the carriage of components and construction of steel structure buildings,a new genre of prefabricated steel structure column-beam node is designed and developed.Quasi-static loading experiments were proceeded on such nodes.Through the summary of the experiment appearances and analyse of the destruction feature of the components,the regression calculation is proceeded on the experimental information,and the skelecton nonlinear mode and the hesteresis force model of the fresh assembly genre joint are established.The consequence suggest that the proposed bend three times line hesteresis force model of the assembled square steel tube column-H-beam can be used as a reference for the theoretical and practical application of the seismic response analysis and design calculation of this genre of steel structure assembled column-beam connection.
