Numerical Study Of Bolted Moment Connections In Cold-Formed Steel Frames, Mohamed El Aghoury, Essam Amoush, Mohamed Soliman

Future Engineering Journal

Bolted moment connections for cold-formed steel frames are considered very important and complicated items which need in depth studies. This paper studies the behaviour and strength of eave connections for members that consist of back to back cold-formed double channels in portal (right angle) steel frames. Relatively new configuration is suggested to facilitate the construction and reduce the cost of this type of connections. The connection is comprised of two stubs (welded built-up I shape) connected with two head plates, each stub is welded to its head plate, keeping in mind that the rafter stub is tapered I-shape.
