A nonlinear analysis method for arch-shaped shell roofs made of cold-formed steel profiles

The paper deals with the problem of static structural analysis of shallow arch-shaped shell roofs assembled from curved cold-formed steel profiles. A nonlinear analysis procedure has been proposed to estimate the stress-strain state of such roof structures. It is based on two interrelated analysis models developed for the purpose – namely, an action effects model used for the static analysis of deformational behaviour of shallow arch-shaped structural systems, and a resistance model, for strength analysis of cold-formed steel profiles.
