Cold-Formed Steel (CFS) framing has been successfully used in a variety of construction applications for many years. Common uses include nonstructural partitions and ceilings, exterior curtain wall and façade support, and complete load-bearing structures, including lateral force-resisting systems (LFRS). Recent advances in the understanding of CFS framing and ongoing research related to the Analysis of seismic force-resisting systems (SFRS) are expected to expand the use of cold-formed steel framing into more complex, robust structural systems. This project focuses specifically on the use of cold-formed steel SFRS in buildings. Standard analysis procedures apply to cold-formed steel analysis. However, because CFS shapes often include elements with high width-to-thickness ratios, limit states not common to other construction materials must be considered in the design process. These limit states are discussed in the Project. The analysis is carried out using E-TABS software. To analyze and compare the structure the 2 models are formulated of 5 stories and 10 stories. The model is symmetric in plan having a 2×2 grid. The main objective of this study is to examine the behavior of cold-formed steel frame considering different modeling systems. All the above cases are analyzed for El Centro earthquake records i.e. Time History Analysis.
