Elastic System Designed for Base Insulation Against Dynamic Action of Vibrations and Seism

Abstract

The approach regarding building base insulation puts into evidence the possibility to evaluate the antiseismic insulation degree in a direction defined using supporting elastic systems having various geometry, structure and antivibrating materials. The antiseismic systems structure is based on the convenient assembly of some elastic and dissipating individual elements so that for rated spectral composition of the earthquake the resonance dynamic response could be avoided. The paper presents three basic technical solutions, Romanian pattented, able to provide very low frequencies and allowing low frequency tunning for the building- supporting elements system
