The usage of cold-formed steel (CFS) is gaining popularity all around the world these days.
Buildings made of such elements as an independent structural system are applied in the
construction of small commercial complexes, low-raised buildings, industrial units, and
single-story sports halls. CFS shear walls sheathed with steel sheets are the most popular
lateral-load resisting system in low to mid-raised structures. In this paper, a full-scale steel
seated CFS shear wall has been simulated by a non-linear finite element method.
Furthermore, parametric studies have been carried out to analyze the effects of the blocking
members, fastener spacing at steel plate to boundary frame connections, and steel sheet
thickness on the behavior of CFS shear wall sheathed with steel plate. It was concluded that
the blocking members prevent the studs from twisting and decrease the local bucking of the
studs. Meanwhile, the results indicate that the thickness of the steel plate affects the shear
strength of the CFS shear wall system to an extent. Besides, increasing the spacing of the
fasteners at the connection of the steel plate to the frame system affects the buckling mode
of the steel plate, and by increasing the spacing of the fasteners from 100 mm to 150 mm
and 200 mm the nominal shear strength of the wall system decreased by 6.5% and 14.1%
respectively, while decreasing the fastener spacing causes web distortion of the boundary
column elements.
