Nowadays the design of seismic-resisting cold-formed steel (CFS) structures are not explicitly covered by European structural standards, even if extensive studies has been carried out in the past decades on this topic and a solid background has long been available. On this basis, with-in the ongoing revision process European structural standards, rules for the seismic design of CFS buildings based on available background studies have been incorporated in 2nd generation of Eurocode 8. Different types of Lateral Force Resisting System (LFRS) are covered, namely CFS strap-braced walls and CFS shear walls with steel sheets, wood, or gypsum sheathing. De-sign rules include a set of provisions for achieving the dissipative behaviour of LFRS, together with behaviour factor values and geometrical and mechanical limitations. A summary of de-sign rules for CFS structures incorporated in 2nd generation of Eurocode 8 and the reference to main background documents are presented in the manuscript. |
