The energy absorbing system in the passive control structure dissipates the energy through the deformation and the velocity of the story caused by the earthquake. It is divided into the two kinds which are the hysteretic and viscous dampers. It has been recognized that these passive control devices are effective to the shear deformation of structure. However, in case of high aspect ratio structures, it is thought that these ones cannot function effectively in the upper floor when bending deformation occurs predominant. As an effective technique of the vibration control, a hybrid passive control structure, which is the hysteretic and viscous dampers are using together in a vertical direction has been proposed in the past study. In that study, the combination-effects by used the hysteretic and viscous dampers together is admitted by numerical analysis for the 40th story steel structural building. In this study, the shaking table tests of 10th story steel model are carried out to show the combination-effects. Moreover, the change in the response characteristic by the difference of the arrangement pattern of the passive control devices is investigated.
