VWD (Viscous Wall Damper)
Viscous Wall Damper is a vibration attenuator using the shear resistance force of a highly viscous fluid.
It consists of outer steel container filled with a viscous fluid and an internal shearing plate.
It is effective for absorbing a wide range of vibrations, from wind vibration to violent shaking caused by strong earthquakes.
VWD can be designed to suit the scale of the building and vibration damping required.
No maintenance is required as the viscous fluid remains stable over many years, and there is absolutely no leakage of fluid.
