“…In particular. An equivalent truss model [44][45][46][47][48][49] uses equivalent nonlinear truss elements or linear truss elements combined with nonlinear springs to predict the behaviour of both strap-braced walls and sheathing-braced walls by allowing relatively simple models that can also be used for whole building structures [50,51]. A shell model [52] utilises shell elements with equivalent mechanical and physical properties that represent the nonlinear behaviour of the entire wall.…”

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 chord studs were modelled as truss elements with physical and mechanical properties representative of chord studs used in tested mock-up (147×50×1.5 mm C back-to-back sections), while the tracks were modelled as infinitely rigid truss elements. More details are available in Fiorino et al [23]. Intermediate studs were neglected in the shear wall models as they are pin connected to their ends and do not contribute to the shear wall response.…”

This paper illustrates the effect of architectural non-structural components on the variation of dynamic properties and lateral seismic behaviour of Cold-Formed steel (CFS) buildings, using shake-table tests and numerical modelling. The seismic behaviour of a two-storey gypsum-sheathed building was investigated as a part of European project ELISSA. Shake-table tests were carried-out on this building under two different configurations: with and without architectural non-structural components. Dynamic properties, such as fundamental period and damping ratio, of both building configurations were evaluated and compared. Numerical models considering all the architectural non-structural components were developed in Opensees environment. Results highlight the importance of considering the contribution of architectural non-structural components, such as finishing materials of shear and gravity walls, partition walls and internal counter walls, in the process of structural analysis and modelling of CFS buildings.

“…At first, numerical model for single wall is developed and calibrated based on the experimental results and then in the later stage, the model of the single wall is incorporated in a complete building model representing the global response of the archetype. The choice of the type of model for single wall and different modelling options available in literature are explained in detail by authors in [14] for CFS gypsum-sheathed shear walls and in [12] for CFS strap-braced walls. A simplified model (Fig.…”

Seismic design regulations rely on certain factors to reduce the earthquake actions due to inherent ductility and overstrength of the lateral force resisting systems. The behaviour factors given in Eurocodes are one such example, which when applied during the design process will ensure the life safety performance level of a building. LightWeight Steel (LWS) structures fabricated with Cold Formed Steel (CFS) profiles are increasingly widespread in earthquake prone regions, however the current in practice edition of Eurocodes fails to acknowledge their seismic performance by not providing behaviour factors for them. The study presented herein addresses this issue by evaluating behaviour factor for the two commonly used LWS systems: CFS strap braced walls and CFS shear walls with gypsum board sheathing through FEMA P695 methodology. For each type of system, a set of archetypes, which represent a range of design parameters and building configurations are designed following the capacity design approach and their response is idealized by nonlinear numerical models. The performance of archetype models is evaluated systematically through the static pushover and the incremental dynamic analysis under a suite of forty-four normalized and scaled earthquake records, representing the probable seismic hazard to the buildings. Finally, by calculating the collapse probability while also considering the uncertainties from various sources, the suitability of a trial value of the behaviour factor used in the design phase of archetypes is evaluated. Based on the results, it is concluded that a behaviour factor of 2.5 and 2.0 for CFS strap braced walls and CFS shear walls with gypsum board sheathing is appropriate.
