The use of thin-walled structures has been increasingly spread in the last few decades due to their big advantages both structural design and construction methods. Therefore, recent researches have discussed a wide range applications. However, resistance such will be decreased by buckling effect; hence, different ways strengthening methods investigated. One this method is lightweight concrete a...

Failure loads of sheet pile having various profiles such as U, Z and Omega/Hat under compression was carried out by using equations strength materials compared the failure load modes Euler’s buckling, torsional buckling due to yielding. Compared flexure finite element analysis. Sheet can be analyzed a unit cell for simplified For selecting with omega/Hat section profile containing one eight num...

Over the last decade, use of cold-formed steel (CFS) sections has increased significantly increasing in lightweight buildings and many other industrial constructions worldwide. The present research paper aims to investigate distributed load capacity CFS buildings. Three built-up were investigated for column three girder a frame building study case. Channels, channels with lip, sigma section, ho...
