摘　　要：提出一种榫卯连接方钢管组装框架结构。对两个方向的平面框架模型进行受力性能试验。介绍试验概况,给出框架模型的竖向荷载与挠度和水平荷载与水平侧移曲线,这些曲线介于刚节点框架和铰节点框架之间,属于半刚性节点框架的范畴。A new kind of assembly steel tube frame with the mortise and tennon joints is proposed in this paper. The plane frame models along the two directions are made and the loading tests are conducted respectively to investigate their mechanical behaviours. Both of the generalized vertical and horizontal load-displacement curves are obtained. The results show that the curve is ranged between the rigid joint frame and the hinged frame, which belong to a semi-rigid connection frame.
