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.
