“…Previous studies have mainly focused on the axial compression behavior of steel stud walls [ [50] , [51] , [52] ] as well as their fire performance [ [53] , [54] , [55] ]. The seismic performance of steel stud walls with various configurations, cover boards, steel stud tube spacings, and openings have been investigated by Restrepo et al [ 56 ], Moghimi et al [ 57 ], Wang et al [ 58 ], Bao et al [ 59 ], Fulop et al [ 60 ], Macillo et al [ 61 ], Fiorino et al [ 62 ], Ye et al [ 63 ] and Wang et al [ 64 ] by series of cyclic tests and the shake table tests conducted by Fiorino et al [ 65 ]. It has been recognized that the cover board makes a considerable contribution to the load bearing capacity and stiffness of the steel stud wall.…”

“…However, the numbers of members and joints constituting the steel-sheathed CFS trussed shear wall were too high for on-site panel construction. Wang et al [22] investigated the seismic behavior and parametric influence of cold-formed, thin-walled, steel tube truss shear walls. The experimental data showed that the shear walls exhibited good hysteretic behavior, ductility and energy dissipation.…”

Studies on the constructability of cold-formed steel (CFS) members are lacking. In this context, this paper proposes an integrated panel to replace the studs and steel sheet in the steel-sheathed wall system used in light gauge steel frames. The integrated panel was developed, to not only exhibit better structural performance and constructability than the steel-sheathed wall system, but to also reflect the appropriate details for applications to on-site panel construction. Cyclic loading tests were performed to investigate the seismic performances of three integrated panel specimens and a steel-sheathed panel specimen. The integrated panel specimens exhibited greater deformation capacity, ductility and equivalent damping ratio than the steel-sheathed panel. Although the web slenderness of the integrated member was nearly 400, the nominal strength of the integrated panel was predictable on an AISI standard. However, for stud-reinforced integrated panels, the nominal strength was overestimated by 45%–60%, and a draft equation was proposed to predict the yield strength of these panels. The proposed equation accurately predicted the yield strength of the stud-reinforced integrated panel specimens. The study results can aid in the construction of light gauge steel frames that require reinforcing parts with a high web slenderness ratio.

“…CFS sections are used in current analysis and design as part of lateral load-resisting systems as steel shear walls. These individual CFS sections are studied in the form of shear wall tests to understand the seismic behavior of cold-formed steel structures, including experimental and analytical models [1][2][3][4]. CFS members sustaining compressive loads are subjected to inelastic buckling deformation that affects their strength and stiffness.…”

This research investigated the axial performance of Cold-Formed Steel, CFS thin-walled Zee sections under cyclic pure axial loading. The experiment studied a zee section with a depth of 200mm and a thickness of 2mm. The experiment program was conducted for three full-scale specimens to examine the three buckling failure modes: local buckling, distortion buckling, and global buckling modes with a length of 600mm,1000 mm, and 2500mm, respectively. The Zee-section web is provided with a notch in the distortion and global buckling specimens to prevent the local buckling formation in the web. The energy dissipation with strength degradation behavior of the Zee section was examined for the three buckling failure modes. The cyclic load-displacement protocol was performed according to the FEMA 461 method depending on the elastic properties of the CFS section. The results showed the failure mode of the CFS zee elements and investigated the axial load-displacement responses and axial load capacity. A Finite Element Model FEM was conducted and validated by the experimental results. The FEM analysis was extended to study the behavior of the cyclic Zee sections with wide ranges of Zee-sections' geometry, including the lip depth, flange width, and thickness.
