In recent years, the technology of Cold-Formed Steel (CFS) structures has gained significant attention due to its superior capabilities in reducing building weight and enhancing earthquake safety. Reducing building weight is a critical factor in structural design as it directly influences seismic forces. In this study, lightweight polystyrene aggregate concrete (PAC) was used to improve the performance of these structures. After validating element models with the experimental results published by Hegyi et al. (2016), the behavior of Cold-Formed Steel (CFS) structures with and without PAC coating was examined under seismic loading. Numerical analyses using ABAQUS software revealed that structures reinforced with PAC coating exhibited higher load-bearing capacity, greater energy absorption, and improved resistance to buckling compared to uncoated structures. Moreover, the lateral displacement of these structures was within the permissible range specified by the codes. The results indicate that using PAC concrete can significantly enhance the stability and performance of structures against earthquakes.
