Seismic design and performance of low energy dissipative CFS strap-braced stud walls

Earthquake Response of Cold-Formed Steel-Based Building Systems: An Overview of the Current State of the Art

“…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].…”

Theoretical and Experimental Evaluation of Seismic Behaviour of CFS Wall With Uhs Steel Bracing

“…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 have highlighted the ability of Steel Structures [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18] and, in particular, Lightweight Steel (LWS) systems made of Cold Formed Steel (CFS) profiles [19][20][21][22][23][24][25][26][27][28][29][30][31], to guarantee high performances, both from structural and environmental point of view. In this perspective, a research project has been just concluded 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.…”

Effect of Architectural Non-Structural Components on Lateral Behaviour of CFS Structures: Shake-Table Tests and Numerical Modelling

“…Nowadays, Cold-Formed Steel (CFS) structures are often preferred to the traditional co nstructions as low-rise buildings in seismic areas due to their light weightiness and good seismic performance [1]. In fact, in the last decades numerous studies on elements [2][3][4], components [5][6][7][8][9][10][11][12] or whole buildings [13][14][15] have evaluated their seismic response. Although structural behaviour has been deeply investigated, only few experimental and numer ical works have been carried out for the evaluation of the influence of architectural nonstructural components on the global seismic response [16,17].…”
