Summary:In this paper, a finite element analysis model for C-section cold-formed steel members partially restrained in its rotational direction by sheeting is established. Analyses are carried out using the model to examine the ultimate load carrying capability of the members when they are subjected to uplift wind loading. The analyses consider the material and geometric nonlinearities. The numerical analysis results show that the sheeting restraints have significant influence on the structural performance of the C-section purlin. It can increase the ultimate load carrying capacity evidently.
