The fluid viscous damper (FVD) consists of a cylinder piston rod filled with viscous fluid. When the structure is deformed, the piston is forced to move in alignment with the cylinder.
The viscous fluid is forced to move from one side through the restrained channel to the other side, which leads to dampening of the force.
When earthquake or wind induced forces act on the structure, the deformation of the structure will induce the FVD to convert the dynamic energy to heat energy via the viscous dampening force. The FVD reduces the deformation of the structure and keeps the structure safer and more durable.
High performance to effectively raise the dampening of the structure
Increase the safety and durability of the structure.
Easy installation to reinforce concrete / steel structures.
Long durability-free maintenance.
Pin joint type or ball joint type are available.
