Cold-formed steel structures have been experiencing a considerable increase in both the civil and industrial building sectors. The introduction of new types of high strength and/or multiple stiffened profiles, as a consequence of improved production techniques, has encouraged the development of innovative applications and structural systems. The consequent need for simple, yet reliable calculation methods of such structures, in turn, has engendered new studies directed at characterizing their failure mechanisms, post-critical behaviour and instability phenomena. This paper provides an illustration and in-depth discussion of the results of a wide-ranging numerical-experimental analysis conducted on multiple stiffened, cold-formed profiles within the framework of the development of an innovative structural application for fabricating industrial cylindrical vault roofing.

Abstract
Cold-formed steel structures have been experiencing a considerable increase in both the civil and industrial building sectors. The introduction of new types of high strength and/or multiple stiffened profiles, as a consequence of improved production techniques, has encouraged the development of innovative applications and structural systems. The consequent need for simple, yet reliable calculation methods of such structures, in turn, has engendered new studies directed at characterizing their failure mechanisms, post-critical behaviour and instability phenomena. This paper provides an illustration and in-depth discussion of the results of a wide-ranging numerical-experimental analysis conducted on multiple stiffened, cold-formed profiles within the framework of the development of an innovative structural application for fabricating industrial cylindrical vault roofing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
