Abstract

On April 6, 2009 (1:32 UTC) an earthquake of magnitude Mw 6.3, originated by a normal fault rupture, shook the Abruzzo Region of Central Italy causing 309 death, hundreds of injured and thousand of homeless. L’Aquila city, which is located very close to the causative fault in hanging wall position, was severely damaged by the event. In this work a study on the characterization of damage potential of strong ground motions recorded during the main shock and the strongest aftershocks is presented. Elastic and inelastic spectral demands, in terms of displacement, forces and energy are estimated and different parameters related to the ground motion records destructiveness are calculated. Moreover, the demand imposed to multi degree of freedom systems is estimated by means of non linear dynamic analyses and compared to the demand to single degree of freedom systems.
