On the basis of foreign research achievements, two kinds of domestic cold-formed steel sections are used as the parent materials to design Rosette-joints. Different styles of joint and various influencing factors (including form of hole, aperture, and the edge distance from the center of joint to the edge of the sheet) are taken into account, and four series of test specimens are schemed out. A series of axial-tension tests on all test specimens are carried out to investigate the shear strength of every rosette-joints.

本文结合国外的研究成果，采用我国常用的两种较大尺寸的冷成型钢型材作为母材来设计插座式连接，考虑了节点的不同形式以及影响节点承载力的各种因素(包括孔形、孔径、端距等)，设计出四组不同形式的节点试件，并对各组试件进行轴向拉伸试验来考察各种类型插座式节点的抗剪承载性能。
