The state-of-the-art of the steel sheathed CFS shear walls has been extensively reviewed by the authors elsewhere [7]. To protect the structural elements of the walls against fire and for the finishing purposes, claddings of different types are being used, which are commonly assumed as non-structural components in design.…”

In this paper experiments are presented to investigate the seismic response of steel sheathed coldformed steel (CFS) shear walls using gypsum and fiber cement board claddings. Six steel sheathed wall specimens of various cladding configurations were tested under cyclic loading.The use of claddings at either or both sides of the walls results in an increase of their lateral stiffness, shear strength and energy dissipation capacity by up to 67, 80 and 76%, respectively.On the use of claddings connected to the CFS walls their effects on the shear strength must be incorporated into the current design specifications for an efficient and safe design.

“…A total of 24 full-scale steel-sheathed CFSF walls with various configurations in studs and screws were tested by Javaheri-Tafti et al [17]. e effects of different sizes of CFS frames and different thicknesses of steel sheathing on steel-sheathed CFSF walls were investigated by Mohebbi et al [18] using 6 specimens. Numerical modeling method for steel-sheathed CFSF walls was proposed by Niari et al [19], and this method was verified by the test results.…”

Seismic fragility of steel-sheathed cold-formed steel-framed (CFSF) structures is scarcely investigated; thus, the information for estimation of seismic losses of the steel-sheathed CFSF buildings is insufficient. is study aims to investigate the seismic fragility of steel-sheathed CFSF buildings with different wall configurations. Analytic models for four 2-story steel-sheathed CFSF buildings are established based on shaking table tests on steel-sheathed CFS walls. en, a group of fragility curves for these buildings are generated. e results show that the thickness of steel sheathing and the fastener spacing of the wall have significant impact on seismic fragility of steel-sheathed CFSF buildings. e seismic fragility of the CFSF building can be reduced by increasing the thickness of steel sheathing or decreasing the fastener spacing. By increasing the thickness of steel sheathing, the reduction on probability is more obvious for the CP limit. It is also found that the exceeding probability is approximately linear with fastener spacing, with a slope in the range from 0.25%/mm to 0.50%/mm.

In the recent years, steel sheet CFS shear wall has been used as a ductile lateral load bearing system for light steel frames. In this study, lateral behavior of this shear wall system is evaluated by finite element modelling of the frame, steel sheet and their connections. The lateral response of the reference wall has been compared to the available experimental data to validate the model. The extended models includes a wide range of the wall parameters such as wall height, steel sheet thickness, spacing of screws, and thickness of the frame members. Also, the influence of these properties of the walls on seismic response modification factor (R) have been investigated. An equal energy concept considering post yielding energy absorption capacity is utilized to evaluate R factor and compare with those calculated according to Newmark and Hall method. This study also aims to realize the failure modes of the steel sheet CFS shear walls and suggest the methods to achieve an appropriate seismic performance. At the end, calculated R factors is compared to those prescribed values in the relevant codes.
