This paper presents an investigation on the buckling behaviour of cold-formed steel channel section beams when subjected to a uniformly distributed load. The focus of the study is on the local and distortional buckling, for which existing results are only for sections subjected to pure compression and/or pure bending. The results obtained from this study have shown that, for local buckling, there...
This paper presents a study on the buckling behaviour of purlin-sheeting systems under wind uplift loading. The restraint provided by the sheeting to the purlin is modeled by using two springs representing the translational and rotational restraints. The analysis is performed using finite strip methods in which the pre-buckling stress is calculated based on the same model used for the buckling analysis...
