     detailed investigation of the lateral performance of k-braced cold-formed steel structures and their response modification coefficients, r factor, are presented in this paper. a total of 12 full-scale 2.4 × 2.4 m specimens of different configurations are considered, and the responses investigated under a standard cyclic loading regime. of particular interest are the specimens' maximum lateral load capacity and deformation behavior as well as a rational estimation of the seismic response modification factor. the study also looks at the failure modes of the system and investigates the main factors contributing to the ductile response of the cfs walls in order to suggest improvements so that the shear steel walls respond plastically with a significant drift and without any risk of brittle failure, such as connection failure or stud buckling. a discussion on the calculated response factors in comparison to those suggested in the relevant codes of practice is also presented.
