Load-bearing cold-formed steel (CFS) walls sheathed with double layers of gypsum plasterboard on both sides have demonstrated good fire resistance and attracted increasing interest for use in mid-rise CFS structures. As the main connection method, screw connections between CFS and gypsum sheathing play an important role in both the structural design and fire resistance of this wall system. However, studies on the mechanical behavior of screw connections with double-layer gypsum sheathing are still limited. In this study, 200 monotonic tests of screw connections with single-or double-layer gypsum sheathing at both ambient and elevated temperatures were conducted. The failure of screw connections with double-layer gypsum sheathing in shear was different from that of single-layer gypsum sheathing connections at ambient temperature, and it could be described as the breaking of the loaded sheathing edge combined with significant screw tilting and the loaded sheathing edge flexing fracture. However, the screw tilting and flexing fracture of the loaded sheathing edge gradually disappear at elevated temperatures. In addition, the influence of the loaded edge distance, double-layer sheathing and elevated temperatures is discussed in detail with clear conclusions. A unified design formula for the shear strength of screw connections with gypsum sheathing is proposed for ambient and elevated temperatures with adequate accuracy. A simplified load-displacement model with the post-peak branch is developed to evaluate the load-displacement response of screw connections with gypsum sheathing at ambient and elevated temperatures.

“…However, previous research [3][4][5][6][7][8][9] mainly focused on screw connections with only a single layer of sheathing material at ambient temperature. In mid-rise buildings, double layers of gypsum sheathing are necessary on both sides of load-bearing CFS walls to satisfy the fire resistance rating of at least 60 min [12][13][14].…”

“…In Italy, Landolfo and colleagues performed CFS-framed wood-sheathed shear wall tests (Landolfo et al 2006), fastener testing (Fiorino et al 2007), prototype structures (Iuorio et al 2014), and complete design philosophies (Fiorino et al 2009). In Romania, Fülöp and Dubina performed CFSframed wood-and plaster-sheathed shear wall tests (Fülöp and Dubina 2006), complementary numerical models (Fülöp and Dubina 2004) and also developed full seismic design procedures (Dubina 2008). Although Australia is not seismically highly active, the early adoption of coldet al (1997b) provided characterization of cold-formed steel-framed, wood-sheathed, shear wall panels that were adopted in the 1997 Uniform Building Code (ICBO 1997) and codified into AISI standards: AISI (AISI 2004), AISI S213-07 (AISI 2007), AISI S213-07/S1-09, and AISI S400-15.…”

ABSTRACT:In the last years, the seismic performance of cold formed steel (CFS) systems has been object of study by a large number of research teams. The main parameters influencing the system behaviour under horizontal loads have been defined and the possible mechanisms of collapse have been identified. Therefore, at the moment, the development of upgraded specifications and design tools that could be readily used by designer is a must. For these reasons, this paper aims to propose a seismic design procedure that allows the shear wall components to be defined in few steps. The procedure is based on the recognized assumption that the best performance of a CFS shear wall is achieved when the sheathing-to-stud fasteners failure is reached. Moreover, it accounts the results of previous studies that defined the relation between behaviour of shear wall and fastener spacing. Hence, by defining three nomographs, the proposed procedure allows the sheathing-to-stud fasteners and all the other shear wall components to be defined. The latter are determined in accordance with capacity design criteria. Finally, the applicability of the presented procedure is verified through a case study.Keywords: Design nomographs, cold-formed steel, housing, linear dynamic analysis, nonlinear static analysis, seismic design, sheathing panels INTRODUCTIONThe growing demand of high performance housing is increasing the interest for cold-formed steel (CFS) structures. These structures are realized with a repetitive number of light gauge cold-rolled steel profiles, produced off-site in controlled environment and, then, assembled on-site with mechanical connections. These characteristics provide them lightness, rapid on-site erection, dimensional stability, high structural performance and considerable potential for recycling and reuse of all the materials. In particular, the spreading use of these constructions in countries as Japan shows the wide applicability of these systems also in seismic zones (Figure1). The global horizontal response of CFS structures under seismic actions basically depends on the shear response of CFS walls that are usually sheathed with metal sheets or panels (sandwich panels, wood-based or gypsum-based panels). Moreover, when the sheathing has adequate strength and stiffness and it is effectively connected with the frame, then the interaction between profiles, sheathing panels and sheathing-to-frame connections can be advantageously taken into account in the structural analysis. In this case, the definition of shear wall elements (studs, sheathing panels, sheathing-to-frame connections, and frame-to-foundation anchors), that constitute the main lateral resisting system in case of seismic actions, is a key point for the design. Currently, a relatively large database of experimental investigations carried out on different CFS wall assemblies subjected to in plane shear loading has been obtained by Gad et al. [7]. As result, the main parameters influencing the shear behaviour of walls have been identified. As a consequen...
