Cold-formed steel frames (CFS) are popular all over the world. In this study, we have investigated 112 frames with different bracing arrangements and different dimensional ratios with different thicknesses of sheathing plates under cyclic and monotonic loading using Finite Element Nonlinear Analysis. We also evaluated seismic parameters including resistance reduction factor, ductility, and force reduction factor due to ductility for all specimens. On the other hand, we calculated the seismic response modification factor for these systems. The maximum modification factor among shear wall panels with sheathing plates related to GWB (gypsum wall board) specimen with thickness of 15 mm was 5.14; among bracing specimens in bilateral bracing mode related to B sample was 3.14. The maximum amount of resistance among the specimens with bilateral (2-side) bracing systems belongs to the specimen C (2-side double X-bracing) with the dimension ratio of 2 (4.8 m × 2.4 m) and resistance of 305.60 kN and also among the shear wall panels with sheathing plates, it belongs to DFP (douglas fir plywood) with a thickness of 20 mm and resistance of 371.34 kN.

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.

Wall System

Improving the lateral performance of cold formed steel systems by employing different sheathing materials and bracing systems has been of particular interest to researchers in these days. However, due to their relatively low seismic capacity, the need for higher shear resistance of these structural systems is still felt. Therefore, this study aims to propose three hybrid shear wall panels in order to provide better performance and higher resistance in seismic zones. The numerical method is verified based on the experimental results in the literature and then is used for evaluating the hybrid systems. The proposed walls are analyzed under lateral and vertical loads and then their performances are compared to each other. The results showed better performance and higher shear capacity for hybrid wall system compared to the ordinary cold formed steel shear wall. In addition, the strength to weight ratio approved the economic application of hybrid panels for high seismic regions.

In this paper, the effect of openings on global performance of Cold Formed Steel Shear Wall Panels is investigated numerically using the ABAQUS software. A benchmark model is first validated in terms of lateral shear capacity and nonlinear behaviour of the CFS-SWP. The failure mode of the CFS-SWP with opening is identified and validated. Subsequently, a parametric study on the effect of size and position of openings is conducted, in which the opening position is found to have a significant impact on the CFS-SWP performance. The benchmark model can be used for design purposes to evaluate with good accuracy the reduced ultimate strength of individual CFS-SWPs for any size and position of openings.
