Shaking Table Tests for a 10-Story Frame Using Combinations of Hysteretic and Viscous Dampers

Abstract eng:
A lot of researches on the seismic vibration control system show that they have effect on mitigating seismic damage. Most researches on structures with damper devices subjected to earthquake ground motions have carried out considering with using the one type of dampers, hysteretic or viscous one, only. However, there have been few investigations for the combinations of dampers with different performances in a vertical direction. The authors have presented the “combination-system” which is the seismic vibration control system using both hysteretic and viscous dampers in the previous research. The combination-system is made up of hysteretic dampers placed on the lower stories of the building and viscous dampers placed on the upper stories of it. Being combined with both dampers brings forward seismic control effects by its multiplier effects. This paper reports the results of the shaking table tests using together with these dampers. The experiments, using a 10-story frame, are carried out to substantiate the progress of seismic control effects by applying combination-system. Performance of specimens is discussed by referring to story shear, relative story displacement, story accelerations and absorbing energy of the dampers. In the combination-system, the characteristics of the hysteretic dampers and the viscous dampers are combined well.
