However, after the buckling-restrained braces yield, the system have a trend of very large story drift and drift concentration. This paper presents an analysis on the seismic behavior of dual system incorporating buckling-restrained braces. Moment resistant frame are considered as backup frame in this paper. The study focuses on the stiffness requirements of backup frame on seismic responses of two different models (4-, and 12-stories) located in general site of Japan and subjected to three sets ground motions with two different seismic levels. Structural behavior is evaluated from story drift angles obtained through nonlinear time history analyses. Performance of the models shows that in order to minimize the story drift angles of the dual system, less then 10% of backup frame stiffness ratio is needed to ensure uniformity of story drifts.
