Abstract
Building systems fabricated with cold-formed steel (CFS) profiles and members made of wood, gypsum, or other materials allow solving a range of issues arising in common constructional elements thanks to their advantages, such as lightness, strength, durability, physical stability, sustainability, and cost-effectiveness. As a result of this inherent competitiveness of CFS based buildings, their use has been gradually increasing in recent years both in the field of structural systems as non-structural architectural components and, above all, in the area of earthquake resistant buildings, where lightness play a key role. After a general introduction, the paper gives an overview of the current codification and ongoing research on CFS non-structural architectural and structural systems. Finally, the main conclusions are summarised, and possible future developments are outlined.

The success of a constructional typology usually depends on the capacity to meet the needs of the market, which is increasingly oriented towards solutions characterised by economic efficiency and ecological performance
The application of cold-formed steel (CFS)-based building systems has been booming over the years both in the field of structural systems as non-structural architectural components and, above all, in the area of earthquake-resistant buildings [1,2,3,4], where lightness play a key role
The whole building seismic response is significantly affected by gravity which can produce significant increase of the lateral stiffness and over-strength
Summary
The success of a constructional typology usually depends on the capacity to meet the needs of the market, which is increasingly oriented towards solutions characterised by economic efficiency and ecological performance. The main CFS structural systems in a building are usually the load-bearing floors and walls. CFS systems in theand fieldfaçade of non-structural components are drywall systems suchapplications as partitions, ceilings, constructions. Systems utilised can in bethese used for making an CFS drywall systems can be used for making an envelope of the building In this case, since the external façades are exposed to moisture, exterior claddings are usually made of waterproof cement panels, and interior claddings are made of gypsum panels (Figure 5). Drywall non-structural architectural components: façades; 2 = waterproof cement panels; 4 = track profile; 6 = thermal insulation material; 7 = gypsum panel.
