“…For the seismic action distribution, floors were considered as in-plane rigid diaphragms. Note that the only steel skeleton without sheathing would have very low capacity and rigidity values, as demonstrated by Fulop et al 2 Taking into account that no specific regulations for the seismic design of CFS structures are provided by the EN 1998 Part 1, 34 a behaviour factor equal to 3.0 and an overstrength factor equal to 1.2 were initially assumed according to previous research. 16 Later, based on the results of tests on full-scale shear walls representative of the ELISSA mock-up, the overstrength factor was increased up to 1.8.…”

“…In the attempt to improve the knowledge about the behaviour of CFS systems, with the final aim to exploit their adoption in seismic areas, many research teams around the world have worked in this field in the last years. In Europe, Dubina and colleagues performed tests on wood and plaster sheathed shear walls and developed numerical models (Fülöp et al), up to seismic design procedures (Dubina). This research group together with the authors of this paper is now proposing the update of Eurocodes, to introduce this structural typology within the Eurocode 8.…”

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.

“…CFS seismic research has begun to use many of the aspects of FEMA P695's methodology to assess its systems. Fülöp and Dubina performed tests on CFS‐framed shear walls with wood and plaster sheathing and developed nonlinear phenomenological models considering observed pinching and strength degradation from tests. They further performed IDA using equivalent bracing with their phenomenological material to model shear wall panels .…”

Summary The objective of this paper is to present incremental dynamic analysis (IDA) and seismic performance evaluation results for a two‐story cold‐formed steel (CFS)–framed building. The archetype building was designed to current U.S. standards and then subjected to full‐scale shake table tests under the U.S. National Science Foundation Network for Earthquake Engineering Simulation (NEES) program. Test results showed that the building's stiffness and capacity were considerably higher than expected and the building suffered only nonstructural damage even at excitations in excess of Maximum Considered Earthquake levels for a high seismic zone. For the archetype building, three‐dimensional finite element models at different modeling fidelity levels were created using OpenSees. The models are subjected to IDA using the far‐field ground motion records prescribed in Federal Emergency Management Agency (FEMA) P695. Seismic performance quantification following the FEMA P695 procedure shows that if the modeling fidelity only follows the state‐of‐the‐practice, ie, only includes shear walls, unsafe collapse margin ratios are predicted. State‐of‐the‐art models that account for participation from CFS gravity walls and architectural sheathing have overall performance that are consistent with testing, and IDA results indicate acceptable collapse margin ratios, predicated primarily on large system overstrength. Neglecting the lateral force resistance of the gravity system and nonstructural components, as done in current design, renders a safe design in the studied archetype, but largely divorced from actual system behavior. The modeling protocols established here provide a means to analyze a future suite of CFS‐framed archetype buildings for developing further insight on the seismic response modification coefficients for CFS‐framed buildings.

“…Through the experimental results, reported in Filiatrault et al (2010), the authors conduct a seismic fragility analysis of partition walls and propose innovative construction details in order to minimize the seismic damage. On the basis of tests experimental results, as those just described, several researchers (Fulop and Dubina 2004a;Fulop and Dubina 2004b;Kanvinde and Deierlein 2006;Restrepo and Bersofsky 2011) propose numerical and analytical model representative of the seismic behaviour of these nonstructural components. In this paper the seismic performance of innovative plasterboard partitions is investigated.…”

The damage of nonstructural components represents the largest contribution to the economic loss caused by an earthquake. Since nonstructural components are not amenable to traditional structural analysis, full-scale experimental testing is crucial to understand their behaviour under earthquake. For this reason, shaking table tests are performed to investigate the seismic behaviour of plasterboard partitions. A steel test frame is properly designed in order to simulate the seismic effects at a generic building storey. The tests are performed shaking the table simultaneously in both horizontal directions. To investigate a wide range of interstorey drift demand and seismic damage, the shakes are performed scaling the accelerograms at eleven different intensity levels.The tested plasterboard partitions from Siniat exhibit a good seismic behaviour, both in their own plane and out of plane, showing limited damage up to 1.1% interstorey drift ratio. The correlation between the dynamic characteristics of the test setup and the recorded damage is evidenced. Finally, an interesting comparison between the experimental results and the analytical model is also performed.
