Abstract

Damage scenarios for the main events of the 2016 Central Italy earthquake sequence have been simulated. In order to describe the seismic performance of the as-built in the area, the mechanic based method simplified pushover-based earthquake loss assessment has been adopted. This methodology has been extensively validated by means of comparison between numerically calculated damage scenario and observed damage. These data have been collected during the surveys in areas hit by earthquakes in Italy in the last 40 years (starting form 1976 Friuli earthquake until 2012 Emilia earthquake). The calculation of damage scenario has been performed in a user friendly WebGIS platform developed for the Italian Department of Civil Protection. The paper gives an overview of methods and informatics tools prior to present the results of the damage scenario. The results of damage scenarios are summarized in tables, charts and maps. Further, improvements of the tools now available are also identified for future developments.
