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.

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.
