Response of base‐isolated buildings to random excitations described by the Clough‐Penzien spectral model

Etude de la reponse stationnaire, en analysant la variation en fonction de la frequence effective du deplacement relatif quadratique moyen base/fondation et du rapport entre les valeurs quadratiques moyennes de l'acceleration absolue au niveau du toit, avec et sans isolation; conclusion sur l'importance de l'effet d'absorption/dissipation d'energie du systeme a base isolee, plutot que sur l'effet de deplacement de la frequence fondamentale
