“…A detailed description of the angle bracket and the connection procedure can be found in the article [27]. Nevertheless, it should be noted that the angle brackets used in this study differ from those listed in the article [27]. The difference is that the angle brackets in this article have additional M12 threaded holes, whereas the brackets in the mentioned article do not.…”

“…They also found that the sheathing can constrain deformation and global buckling, resulting in local buckling being the primary limit state for all practical lengths. There are numerous other theoretical and experimental studies in the literature [22][23][24][25][26][27] that have investigated the effects of various factors on the ability of such wall systems to withstand axial loads, such as the spacing between screws, the shape and spacing of studs, the type of sheathing, the presence of holes or notches in the studs, and the height of the wall studs.…”

Experimental Investigation of the CFS-PU Composite Wall Panel under Axial Compression

This study presents an innovative design for a cold-formed steel polyurethane (CFS-PU) composite wall panel, combining a cold-formed steel frame, a polyurethane foam infill, and a gypsum fibreboard sheathing. The foam filling process, in which the foam is injected under pressure, ensures uniform distribution, bonding, and interaction of all panel components. The aim of the study is to evaluate the behaviour of the CFS-PU composite panels and the influence of the PU foam and sheathing on the performance of the CFS frame structure. For this purpose, a comprehensive test programme was conducted with nine full-scale specimens, including four CFS-F specimens without infill and sheathing and five CFS-PU specimens with infill and sheathing on both sides. The study examined various aspects of the specimens, including failure modes, stability, stiffness, load-bearing capacity, and ductility index. By analysing these parameters, valuable insights were gained into the performance characteristics of the composite wall panels. The load-bearing capacity of the CFS-PU test specimens was improved by 2.34 times and the stiffness by 1.47 times compared to the CFS-F test specimens. The positive results highlight the potential of foam and sheathing in improving the axial compression performance of CFS walls.

“…In addition, their components can be prefabricated in the factory so that they can be handled and constructed at the construction site more easily. [1,2] The most usual form among the Cold-Formed Steel Shear Wall (CFSSW) is the "Cold-Formed Steel (CFS) framing sheathed on one side or both sides", namely a CFS framing with different sheathings applied to one side or both sides of the members. The precedent researches on CFSSWs have put emphasis on their basic mechanic capacities, including axial load bearing capacity [3 -5] and lateral performance [6 -9], as well as factors contributing to them.…”

A series of researches on the behaviour of a new structural system, composite timber wall panel with cold-formed steel frames, are investigated under monotonic and reversed cyclic loading. In order to improve the in-plane lateral performance of the composite timber panels, sixteen different optimized composite timber panels were proposed and tested, including increasing the thickness of the sheathings, improvement with steel X-bracings, filling with straw and advance of connection between sheathing and wood framing. The main objective of the investigation is to explore the pervasive mode of failure, determine the quantification of the improvement in lateral performance of these optimized composite timber wall panels and evaluate the benefits of each optimization during the process of failure.

Background and Methods:This paper illustrates a research on the behavior of the composite timber panels used in a new-type cold-formed steel shear wall, when subjected to monotonic and reversed cyclic in-plane loading. The framing members of this new-type cold-formed steel shear wall are made of cold-formed steels. The inner timber frameworks, sheathed with veneer plywood, form the composite timber panels. Objective:In order to improve the lateral performance of the new-type cold-formed steel shear wall, two different optimized composite timber panels were proposed and tested, namely, increasing the thickness of the sheathings and the addition of steel X-bracings. The main objective of the study is to determine the quantification of the improvement in lateral performance of these two optimized composite timber panels. Results and Conclusion:Observed failure modes, structural performance parameters and the data of the strain gauges were given for each specimen, which indicates two optimized panels both have better lateral performance. But larger deformation and damage of the sheathings happened on the panels with steel X-bracings, so the panels with thick sheathings are more suitable and practical for normal use.
