Structural member stability behaviour of steel channels
In structural engineering, steel channels are often used for girders of facade constructions of steel halls, platforms, gangways and stair stringers. Since the loads are often applied to the flanges of the mono‐symmetric cross‐sections the channels are most commonly subjected to scheduled torsion. So far, a simplified design method for steel channels in bending, compression and torsion is missing.
Based on an experimental study, this paper analyses the structural behaviour of steel channel members in bending, compression and torsion. An integrated experimental and numerical study analyses the structural member stability behaviour. The study includes the analysis of the load‐rotation behaviour, of the development of internal forces and moments during load increase as well as of the residual elastic cross‐sections as a result of the development and spreading of plastic zones. Finally, the paper compares the ultimate loads of three verification methods, that are adopted and extended for steel channels, with experimental results.
