HIFLUID VDD

FLUID VISCOUS DAMPERS

The large amounts of energy dissipation solution for span or suspension bridges and tall buldings.

The HIFLUID VDD devices allow slow movements (creep, shrinkage and temperature effects) with negligible reaction but they maximise the energy dissipation of the device for dynamic motion (earthquake), modifying the seismic response of the structures and reducing the effects of an earthquake.
