This paper presents seismic performance of moment resistant frames with hysteretic dampers designed with allowable stress design method according to the building standard law of Japan. In this paper, moment resistant frames (4, 8, 12-story) with and without hysteretic dampers (the buckling-restrained braces) are designed in order to compare with their seismic responses. The difference of seismic responses of the two kinds of frames is investigated on maximum story drift angle, damage of beams and cumulative ductility factor of hysteretic dampers by numerical analysis with both conventional frame and fishbone-shaped frame model.
