VED (Visolastic Damper)

A viscoelastic damper is a type of damper related to velocity. It consists of two outer steel plates and an inner steel plate positioned between them. A viscoelastic material is placed between the steel plates.

Viscoelastic dampers have a reliable performance and a simple structure. They can effectively reduce the wind and seismic responses of buildings, making them widely applicable in engineering projects.

Fundamental Principle

Viscoelastic dampers enable the viscoelastic material to undergo repeated shear deformation. This process generates a distinct cyclic hysteresis curve, allowing the damper to absorb and dissipate energy. By providing additional damping resistance to the structure, viscoelastic dampers help reduce its dynamic response and mitigate seismic effects.
