In our previous study, we proposed the new structural system which amplifies effective damper deformation, and showed the amplification
of damper deformation and the high damping effect by the analysis for high-rise building. However, this study has yet to show the
amplification effect of the effective deformation in the experiment. In this paper, the amplification of damper deformation in the proposed
system are confirmed by the dynamic vibration tests. In addition, to investigate the influence of damper location, tests are conducted on 2
types of specimens varying in damper location.
