Isolation techniques of construction structures against seismic actions using viscous fluid systems

Abstract

The topic of construction structures isolation against earthquakes destructive actions has been regarded as a matter of major importance. Various protection systems have been designed and developed over time in order to be attached to construction structures so as to improve their seismic safety. One isolation method is represented by the use of hydraulic systems aiming to take over and dissipate a part of the earthquake energy so that the dynamic action effect on the structure be greatly diminished. Such a system, called fluidic system because of its fluid dependent operation, is described and analyzed from the operation point of view of in this paper.
