Energy dissipation device using fluid dampers

Résumé

This scientific paper presents a solution that is adequate for the seismic isolation of small and medium size buildings and bridges. Comprising two seismic isolating devices, the described arrangement is suitable for dissipating an increased level of energy induced to infrastructure by the seism. As other hybrid arrangements, this one uses viscous dampers in order to limit the distance of induced movement of the infrastructure. The internal design of the fluid damper is analyzed using CFD software, to ensure a proper dissipation of the seismic action and to limit its destructive effects.
