Seismic response assessment of architectural non-structural LWS drywall components through experimental tests

Abstract

A research project was conducted at University of Naples "Federico II" over the last few years with the aim to give a contribute to overcome the lack of information on seismic behaviour of architectural

Nonstructural Seismic Loss Analysis of Traditional and Innovative Partition Systems Housed in Code-conforming RC Frame Buildings

“…DS3 was never reached over the reference experimental tests on plasterboards (i.e., both SP and IP partitions) (Etex Innovation and Technology (EIaT) centre 2018; Magliulo et al 2014;Petrone et al 2015). Therefore, the related capacities were derived from the studies performed by Landolfo et al (2019) and Pali et al (2018), who carried out quasi-static tests on standard and enhanced plasterboard partitions. In particular, the former partition system corresponded to SP system investigated in the present paper, whereas the latter was quite similar to IP one.…”

“…In particular, the former partition system corresponded to SP system investigated in the present paper, whereas the latter was quite similar to IP one. Shake table tests were also performed by Landolfo et al (2019) and Fiorino, Bucciero, and Landolfo (2019) on the same partition systems. However, these latter tests supplied capacity thresholds for DS3 that were significantly higher than the quasi-static ones.…”

“…Infills and partitions typically account for a significant part of the total NC costs (Restrepo and Bersofsky 2011). Infills and partitions were extensively studied in the past few decades, and their seismic performance was widely assessed through both experimental testing (Di Fiorino, Bucciero, and Landolfo 2019;Landolfo et al 2019;Magliulo et al 2014;Onat et al 2018;Pali et al 2018;Petrone, Magliulo, and Manfredi 2014;Restrepo and Bersofsky 2011;Tasligedik, Pampanin, and Palermo 2015;Verderame et al 2019) and numerical methods (Petrone et al 2018;Wang et al 2020;Zhai et al 2018). These components are sensitive to interstory drift within their plane (i.e., in-plane (I-P) damage mechanisms) and accelerations along their out-ofplane direction (i.e., out-of-plane (O-O-P) damage mechanisms) (Petrone, Magliulo, and Manfredi 2017).…”

Innovative UHS Steel Material for Tension-Only Braced CFS Walls

“…A joint synergy between different engineering fields can lead the path of innovation and hence making our constructions increasingly safe, sustainable and comfortable. Recent research activities carried-out at University of Naples "Federico II" have highlighted the ability of steel systems [1][2][3][4][5][6][7][8] and, in particular, Lightweight Steel (LWS) systems made of Cold Formed Steel (CFS) profiles [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], to guarantee high performances, both from structural and environmental point of view. In this perspective, a new research project has been started at University of Naples "Federico II" in cooperation with Lamieredil S.p.A. Company, which aims to develop innovative technological solutions with higher structural and environmental performances, through the use of Ultra High Strength (UHS) steel.…”
