Viscous Fluid Damper

Viscous fluid damper is a kind of hydraulic device, which have no initial stiffness and no additional internal force to the structure, so it will not affect the structure's period, vibration mode, etc. But for rapid deformation cause by earthquake, it can rapidly consume energy and reduce the acceleration and displacement of the structures.

Viscous fluid damper has the advantages of smaller size, convenient installation and maintenance, great durability, and insensitive to temperature.
