Solid viscoelastic Dampers
Solid Viscoelastic Dampers are an ideal technology for seismic and wind sensitive retrofit projects as they add both stiffness and damping to the building structure. In retrofit projects numerous connection details can be implemented depending on the existing structural deficiencies and structural configuration including, but not limited to wall dampers, brace dampers and viscoelastic coupling dampers (VCDs). Viscoelastic dampers reduce drifts, forces and minimize structural damage for frequent and large earthquakes.
