In this study response modification factors of rectangular reinforced concrete staggered wall system (SWS) structures were evaluated according to ATC-63. The adjusted collapse margin ratios of the model structures obtained from incremental dynamic analyses turned out to be larger than the specified limit states, which implies that the analysis model structures have enough safety margin for collapse against design level earthquakes. It also was concluded that the response modification factor, 6 used in the design of the model structures was valid.
