“…Researchers from the US and Canada were very active in last few years, with studies of Yu [16] on steel sheathed shear walls; Peck et al [24] on gypsum sheathed shear walls; Schafer et al [20] on wood sheathed shear walls with gypsum panels on the interior faces of walls and ledger in some cases; Velchev et al [25] and Mirzaei et al [26] on strap-braced walls. In Europe, Mohebi et al [27] studied steel sheathed shear walls with layers of either gypsum or fibre cement board panels on the interior side; Accorti et al [28] tested walls having a combination of strap braces inside and cement sheathing panels on the outside; Macillo et al [6] tested shear walls sheathed with gypsum panels having different aspect rations by including the influence of non-structural finishing; Fiorino et al [29,30] studied the experimental cyclic behaviour of low dissipative strap-braced walls. Even in Asia and Australia, some research teams have been very active on this task, with the walls sheathed with various combinations of board panels tested by Ye et al [31,32], steel sheathed walls studied by Esmaeili Niari [33], and strap-braced walls having different positions of bracings tested by Moghimi and Ronagh [34].…”

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 wall test program is summarized in Table , in which each tested configuration is illustrated. Only tests on 2.4‐m‐long walls have been considered in this paper because test results obtained for the specimen WS_4100_C (4.1‐m‐long wall) were affected by the presence of imperfect connections between the panel edges and the internal studs, as discussed in Macillo et al…”

“…The wall test program is summarized in Table 9, in which each tested configuration is illustrated. Only tests on 2.4-m-long walls have been considered in this paper because test results obtained for the specimen WS_4100_C (4.1-m-long wall) were affected by the presence of imperfect connections between the panel edges and the internal studs, as discussed in Macillo et al 17 The structural elements of wall specimens were defined on the basis of the seismic design of the ELISSA mock-up. The seismic action was evaluated by assuming a reference period of 50 years (nominal service life for ordinary buildings) and an intensity corresponding to a typical value of European areas with medium seismic hazard, ie, a reference peak ground acceleration (PGA) of 0.25 g for type A soil (10% probability of exceedance in 50 years) for life safety limit state.…”

Summary Lightweight steel buildings made up by cold‐formed steel (CFS) members as main structural components are growing in popularity in the most industrialized countries. Cold‐formed steel buildings start to be adopted also in seismic regions thanks to their efficient fabrication, reduced site work, short time of construction, and good structural performance. However, the dynamic properties and full seismic performance of CFS buildings completed with finishing is an open question. This paper attempts to provide a contribution to this research question, by a full experimental campaign aiming at investigating the dynamic properties of a modular building developed within the “Energy efficient LIghtweight Sustainable SAfe steel construction” (ELISSA) research project. The work shows the results of an international collaboration between universities and industrial partners aimed at developing a CFS prefabricated dry construction system with improved antiseismic properties and energy performance. This work will discuss the design of the modular building named ELISSA house, the experimental investigation going from small‐scale tests of components, to static tests of shear walls, up to shake table tests of a 2‐storey mock‐up building. It will analyze the dynamic properties of the structural system compared to the building completed with all the finishing, focusing on fundamental period of vibration, damping ratio, building drift, and observed damage.

“…Therefore, the robustness of a steel structure made of ductile and compact members is highly influenced by the response of its joints, as highlighted by several experimental and numerical studies recently carried out on structures undergoing progressive collapse at the occurrence of a column loss scenario [4][5][6][7]. This is not the case of lightweight structures [26][27][28][29][30] where the poor ductility of the all structural components affect the ultimate behavior.…”

Steel joints for moment resisting frames in seismic areas are designed in accordance with the capacity-based design principles This design philosophy can be also effectively implemented to enhance the robustness of structures against progressive collapse. In this article the effectiveness of seismic design criteria on the robustness of beam-to-column joints is investigated. The numerical investigation was carried out on a set of European beam-to-column assemblies equipped with extended stiffened end-plate connections. The beams in the analyzed models were axially-restrained and subjected to large rotational demands, characteristic of the column loss scenario. The results show that the joints designed in accordance with seismic requirements have an adequate performance, provided that the axial resistance of half of the connection is larger than the plastic resistance of the beam.
