Fluid viscous dampers for high-rise buildings

Using supplemental fluid viscous dampers to dissipate energy and reduce building response to dynamic inputs is gaining worldwide acceptance. The concept of supplemental dampers added to a structure is that they absorb much of the energy input to the structure from a transient, not by the structure itself, but rather by supplemental damping elements. This paper presents an application of fluid viscous dampers in a high-rise structure to suppress the anticipated wind-induced accelerations. The description of the damping system, the design criteria and cost data are discussed. The viscous damper system proves to be a very cost-effective method to reduce wind motions.
