The Comparison between Viscous Fluid Dampers and Romanian Friction Dampers Performance in Base Isolation System of Buildings

Abstract:

This paper analyse the performance of two types of devices used for protecting the building against collaps during earthquakes. These devices are used in paralell with the base isolation system of the building and are intended to increase the damping phenomenon in order to dissipate the quakes energy received by the resistance structure of the buildings. The purpose of this computational study is to determine if these friction dampers, which are four times less expensive than the classical viscous fluid dampers, can replace the classical choice in order to obtain a less expensive protection. The results obtained at the final of this study are encouraging because the damping performances of romanian telescopic devices are similar with the performances of classical viscous fluid devices in base isolation system.
