Buildings which was constructed before 1988 were not satisfied seismic design code. Thus, most of these buildings have to retrofit for remodeling. This study proposed the steel slit damper system with displacement-amplification device. It could maximize the effectiveness of a damper system in controlling seismic response of a building by amplifying story drift induced to damper. In this study, the proposed system was verified the effect of displacement-amplification using the analytical and experimental study. From the analysis and experiment, it was found that the propsed damping system showed a stable hysteric behavior with excellent energy dissipation capacity. Therefore the proposed system will make a good seismic performance and economical benefits.
