Étude paramétrique d’une structure en béton armé avec système d’isolation

Abstract

The analysis of structures subjected to seismic action is a current field of research and is of particular interest in countries where seismic activity is significant. The Algerian seismic regulation (RPA) considers the north of Algeria as a high seismic zone, Algeria is exposed to the risks of such shocks. Could cause to financial and human problems. Our work aims to shed light on the parametric study of a reinforced concrete structure with and without a shrink-wrapped elastomer type insulation system with the sizing of these supports for this the analysis was carried out by the software (ETABS). A comparison was made between the displacements and the shear forces at the base of the structures, the results obtained showed that the structure equipped with seismic insulation makes it possible to significantly reduce the displacements between floors, it behaves almost like a body rigid. Regarding the appropriate period of the isolated structure as a whole; It's quite long considering the great horizontal flexibility.
