摘　　要：基于钢管混凝土柱与钢筋混凝土密肋扁梁连接的新型不穿心节点型式,进行了典型节点的静载试验。介绍了试验方案、试件制作、加荷方式、试件的裂缝发展情况及破坏形态等。试验结果表明,新型节点整体上设计合理,传力明确,易于施工;在高层建筑中新型节点可极大降低节点区空间,具有良好的安全和经济性。Based on presented novel non-through-core concrete-filled steel tubular connection with flat beams with dense ribs, static experiments on typical connections have been fulfilled. The experimental scheme, fabrication of specimens, loading system, development of cracks and failure models are described. Experimental results show that the design of the novel connection is reasonable, force transmission is clear and it is easy to be constructed. The usage of the novel connection will reduce the space around connection, thus it＇s economical for the high-rise building to adopt the novel connection.
