Experimental study on screwed connections for sheathed CFS structures with gypsum or cement based panels

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

“…Recent studies have been particularly concentrated on connections between CFS profiles and sheathing panels, as represented by research carried out in the US by Vieira and Schafer [38] and Peterman et al [39] on wood and gypsum-based sheathing connections, and by Swensen at al. [40] on gypsum sheathing connections; tests performed on different typologies of boards in China [41], i.e., wood, gypsum, magnesium, and calcium silicate boards; studies on gypsum-based sheathing connections carried out in Italy [42,43]. The main results of available studies on sheathing panel-to-steel connections demonstrate that the type of sheathing had a significant effect on the shear response of connections: pull-through is dominant for wood-based sheathing connections (Figure 11a), which show a comparatively larger strength and energy dissipation capacity; whereas, bearing is dominant for gypsum-based sheathing connections (Figure 11b), which show a relatively larger stiffness and ductility.…”

Characterisation of material and connection behaviour in sheathed cold-formed steel wall systems – Part 2: Analytical modelling

“…When a sheathed wall is subjected to compressive or lateral loads -or a combination of these two -shear and pull-through forces develop at the interface between the stud and the board, leading to their relative slip and separation, respectively [8][9][10]. Resistance to these forces is provided by the employed connection, while rotation and twisting of the elements is restrained mainly through contact [4,11].…”

Experimental study on screw connections in cold-formed steel walls with cement sheathing

“…Nithyadharan and Kalyanaraman (2011) and Ye et al (2016) presented experimental studies on screw connections between CFS and calcium silicate boards (CSB). Fiorino et al (2008Fiorino et al ( , 2017aFiorino et al ( , 2017b, Swensen et al (2015), and Shahi et al (2013) presented experimental studies on cement-based boards (CB). Ye et al (2016) performed an experimental study on screw connections of Bolivian magnesium board (MGB).…”
