Abstract

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.
