Effect of geometric imperfections on the ultimate moment capacity of cold-formed sigma-shape se
HBRC Journal, 2017 In recent years, cold formed steel sections are used more and more as primary framing components and as a secondary structural system. They are used as purlins and side rails or floor joist, and after that in the building envelops.

INFLUENCE OF GEOMETRICAL AND STRUCTURAL IMERFECTIONS OF STEEL PLATE GIRDERS
Facta Universitatis. Series: Architecture and Civil Engineering, 2021 The girders or parts of the girders are not ideally flat in terms of their geometry. The deviations that occur are defined as geometric imperfections.
