“…Natesan and Madhavan [7] conducted an experimental work on the CFS beam-to-column two-bolted shear connection and proposed a new shear design equation. Natesan et al [8] investigated three bolted shear connections under monotonic load and noticed an inverse relationship between the aspect ratio and ultimate shear strength.…”

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.

“…Many research works were conducted on the cold-formed steel connection to understand its complicated behavior and provide appropriate design guidelines [1][2][3][4][5][6][7][8][9][10][11][12]. Chung and Lawson [1] performed experiments on the web cleat shear connections between CFS beam and column under monotonic load.…”
