Proposal for New Deformation Amplification System To Increase Effect of Seismic Dampers

Abstract eng:
The amount of energy dissipated by seismic dampers increases with their deformation. In typical structures with passive energy dissipation systems that utilize seismic dampers to withstand earthquakes, the dampers displace along with with respect to the story drifts in the building. This however restricts the displacement of the damper to the story drift, limiting the amount of energy the dampers dissipate. Deformations larger than the story drift need to be applied to maximize the effect of dampers, while ensuring that encompassing frame is strong enough to withstand the forces of the dampers. In this paper, a new method is introduced, which creates a deformation amplification mechanism to maximize the effect of seismic dampers. Stiff frames are extended from columns and at the end of these frames, dampers are attached using pin connections. Using this method, oil dampers and tuned viscous mass dampers (TVMD) can be placed on high-rise buildings to exhibit larger effects than in the typical installation of dampers. Earthquake response analysis is conducted to confirm the effects of this new method.
