As high-rise buildings become taller and more slender, dynamic behavior becomes a critical design consideration. Wind loads cause large vibrations which can be perceived by building occupants, while severe earthquakes can cause building damage. Current damping systems can be used to reduce vibration perception, however they can't reliably be used to reduce wind or earthquake design loads. The Viscoelastic Coupling Damper (VCD) increases the level of damping of the structure such that dynamic effects are considerably reduced. Damping is provided by incorporating VCDs in lieu of coupling beams and therefore do not occupy any valuable architectural space. This paper provides an overview of the system, its development, its performance benefits and a tall building case study incorporating VCDs.
