Working Characteristics of the Special Isolation Devices Against Vibratory Actions

Abstract

The actual researches for finding optimal antiseismic protection solutions are straightening to the few areas of activity: the first area of research is the base isolation of buildings or theirs parts, against the vibrations and earthquake actions. The second area of activity, in anti-seismic protection domain, is the isolation of vital equipments of public buildings endowment, against the seismic waves or undesirable vibrational movements. In essence, the antiseismic systems manufacturing are based on suitable ensembling of individual elements with elastic and damping properties, so that at standard earthquakes spectral composition should be avoid the resonance dynamic response. This paper emphasize a technical solution of isolation elastic system, copyrighted in Romania, which are capable of very low natural frequency, so that it is possible low tunnig of ensemble of building - isolation system.
