MODELISATION DE SYSTEME D’ISOLATION PARASISMIQUE POUR LE CONTROLE DE LA REPONSE DYNAMIQUE DES STRUCTURES

Abstract

For a seismic increased protection, new technologies have been developed among which are the "passive energy dissipation devices." The absorption of most of the seismic energy input in the primary structure of buildings and reducing as much as possible damage to structural elements is the main objective of these devices. In this work, a modeling of viscous fluid linear device is performed as passive energy dissipation system to control the dynamic response of structures due to a seismic motion. A comparative study with a traditional structure is conducted to analyze the influence of this type of damping on the dynamic behavior of the structure. The effect of the location of these devices in the dynamic response of structure is also studied.
