Numerical Study Of Bolted Moment Connections In Cold-Formed Steel Frames, Mohamed El Aghoury, Essam Amoush, Mohamed Soliman
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. The web …
Compressive Strength Of Axially Loaded Built-Up Sigma Cold Formed Sections Columns, Mohamed El Aghoury, Maged Tawfic, Essam Amoush
Compressive Strength Of Axially Loaded Built-Up Sigma Cold Formed Sections Columns, Mohamed El Aghoury, Maged Tawfic, Essam Amoush
Future Engineering Journal
The use of cold formed steel sections in building constructions has lately seen rapid growth due to their light weight and easier erection. Generally, lipped channel sections are used more frequently .Sigma sections while requiring more effort in fabrication, they exhibit high strength to weight ratios compared with the lipped channel sections. This work presents experimental as well as numerical study of the strength of pinned-pinned axially loaded columns utilizing sigma sections. The column section consists of two back to back sigma cold formed sections. The two sections are connected through their webs with connecting fasteners. Eight specimens with variable …
