In this study, we investigated six full-scale, steel-sheathed, cold-formed steel shear walls (CFS-SWs), three of which were CFS-SWs with reinforced end columns (CFS-SW-Rs), under reversed-cyclic loading and analyzed their damage modes and mechanical properties. Tests were conducted to compare the seismic performance between the CFS-SWs and CFS-SW-R...
To study the seismic behavior of two types of walls under horizontal reversed-cyclic loading, 6 full-scale cold-formed steel plate shear wall (CFS-SPSW) specimens were designed. They each had three specimens. The effect of the vertical stiffener and the cross-section form of end stud on the seismic behavior of the cold-formed steel center-sheathed...

This study experimentally investigated the mechanical properties, failure modes, and lateral resistance of oriented strand board (OSB) sheathed cold-formed steel (CFS) shear walls under monotonic loading and reversed-cyclic loading. The influences of the loading mode, vertical load, ratio and local strengthening of openings, sheathing panel, and di...
Through an experimental investigation of the lateral resistance of seven full-scale cold-formed steel (CFS) framed sheathed walls under monotonic loading and reversed-cyclic loading, the mechanical properties, failure modes, and seismic performance of the walls are elucidated. The influence of loading mode, vertical load and sheathing material on t...
Presented in this paper are results obtained from experimental and numerical investigations on the axial behavior of cold-formed thin-walled steel channel columns with complex edge stiffeners, which are referred to as G-section columns. In the experimental investigation, a total of 36 G-section columns, with and without perforations, were tested un...

... Associated with the increasing adoption of LSF-built houses, it was not surprising to observe a growth of research studies in this specific area, as several experimental [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] and numerical [14,19,21,22] studies were developed to investigate the mechanical behavior of LSF structures. Recently, Hasanali et al. [23] published a critical review of the developments and challenges related to the behavior of LSF seismic-resistant systems. ...

... It has high strength, is lightweight, makes easy connections, has convenient installation and recyclability, and is widely used in low-rise buildings [2]. Ordinary sheathing materials include steel plates [3,4], fiber cement boards (FCBs) [5], gypsum wallboards (GWBs) [6], oriented strand boards (OSBs) [7], Bolivian magnesium boards (BMGs) [8], and calcium silicate boards (CSBs) [9]. ...

... The mechanical behavior of the CFS wall is mainly influenced by the CFS frame. When this wall is applied in low-rise light structure residences, the LSF walls are usually used as a load-carrying member to withstand gravity loading and seismic action (Badr et al., 2019;Xu et al., 2021). The moment-resisting performance of the CFS frame was concerned (Mojtabaei et al., 2018(Mojtabaei et al., , 2021Ye et al., 2020). ...
... Cold-formed steel (CFS) members with web holes have been used widely in the recent past due to their lightweight structure, cost-effective advantages over the entire construction cycle, structural efficiency, practicality, etc. They are often employed as columns [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16], beams [3,4,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31], and the load-bearing structures of sheathed panel shear walls, light frame strap-braced walls, partition walls, curtain/facade walls, floor joists, etc. Mainly, the C-, Z-, and Σ-sections and their varieties are used. The most common cross-section shapes and 3D models of CFS members with circular web holes are presented in Figure 1. ...
