“…According to the conventional design method, the outstanding leg of the clip-angle is assumed to be a rigid bar that deflects uniformly in an elastic state until the serviceability deflection limit of 1/8 inch or 3.175 mm. The serviceability deflection limit of 1/8 inch was suggested for the CFS connectors (here it is welded clip-angle) and the same approach was followed by Yu et al [10]. The authors refer to this conventional approach as method-1 in this paper.…”

“…Yu et al [9,10] and Zhang et al [11]suggested design methods for the limit state of serviceability design of the clip-angle connection under shear, compression, and tension. Yu et al [9] examined the compression strength of the cantilevered leg of cold-formed steel clip-angle connectors and proposed a new design method for the thinwalled plate columns based on elastic deformations.…”

The present research endeavours to experimentally evaluate the service shear strength of the cold‐formed steel (CFS) welded clip‐angle connector in a CFS beam‐to‐column connection. A total of 30 laboratory tests were conducted on the 27 configurations of the clip‐angle by varying its thickness, width, and depth. The governing design failure modes observed in the welded clip‐angle are (i) Local buckling and (ii) Distortional buckling. The existing traditional elastic design approach for the service limit state design of CFS connector was found to be highly conservative for most of the welded clip‐angle specimens. Hence a new design approach is developed for the welded clip‐angle configuration and the corresponding design shear equation is suggested. A comparative study was conducted between the present welded clip‐angle configuration and existing screwed configuration. The design recommendations were suggested for the efficient design of the connection for the welded clip‐angle configuration. The relevant design factors for the suggested shear equations of welded clip‐angle were evaluated from the reliability analysis.

Cold -formed steel (CFS) members are gaining importance as a material of choice for low-rise residential construction in the developing world. The floor system used in such structures are constructed using CFS beams in a grid pattern. The CFS beams are typically connected utilizing clip angles whose rotation and ductility behavior is the focus of the present research. A total of 24 numbers of beam to beam connections with different connection configurations were tested to investigate the performance of clip angle connections concerning moment and rotational stiffness. The connection configuration parameters studied include four different aspect ratios for loaded leg, 3 different aspect ratios for anchored leg and two different thickness of clip angle. It was observed that the ultimate load of the clip angle bolted connection depends on the thickness and aspect ratios of clip angle. The maximum rotational stiffness value was obtained in the connection configuration 1.5 1X3.2-3. The rotational stiffness versus percentage of ultimate moment depends on the anchored leg aspect ratio. The strain deformation measured in both legs of the clip angle and on both sides of the member connection between the loaded member and anchored member and on the anchored member helps to describe the clip angle behavior and loaded CFS member.
