A conventional approach would dictate that the structure must inherently attenuate or dissipate the effects of transient inputs through a combination of strength, flexibility and deformability. By adding fluid viscous dampers, the energy input from a transient is absorbed, not by the structure itself, but rather by the supplemental dampers.

INTRODUCTION Fluid viscous damping is a way to add energy dissipation to the lateral system of a building structure. A fluid viscous damper dissipates energy by pushing fluid through an orifice, producing a damping pressure which creates a force. These damping forces are 90 degrees out of phase with the displacement driven forces in the structure. This means that the damping force does not significantly increase the seismic loads for a comparable degree of structural deformation and deflection. The addition of fluid viscous dampers to a structure can provide damping as high as 30% of critical, and sometimes even more. This provides a significant decrease in earthquake excitation. The addition of fluid dampers to a structure can reduce horizontal floor accelerations and lateral deformations by 50% and sometimes more. 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 and resist seismic lateral loads and deflections of structures. The Fluid Viscous Damper is an equipment protecting structure from damage in earthquake or strong wind.
