This paper is developed the viscoelastic dumpers whose multilayer system absorbs weight transmitted to framed structure sliding down along specific layer elements. Experiments with and without viscoelastic dumpers were carried out. According to the results, I could confirm that interstory drift ratio of steel frame structure has effectively decreased on both 1st and 2nd floor compared to that of before.
