Assessment Survey of Public School Buildings After August 2016 Italy Earthquake: Preliminary Results


Abstract eng:
The seismic events which hit Central Italy on 24 August, October 26 and October 30 2016 have caused casualties and major damage mostly to buildings and architectural heritage of the Italian Regions of Abruzzo, Lazio, Marche and Umbria; the most deadly events occurred on August 24, 2016 and caused a total of 298 victims and about 4.600 people evacuated. The mainshock occurred at 3:36 am with epicenter close to Accumoli (Rieti province) and a magnitude Mw 6.0; the aftershock occurred at 4.33 am with epicenter close to Norcia (Perugia province) and a magnitude Mw 5.3. Most of the victims were in the areas of Amatrice (Ri), Accumoli (Ri) and Arquata del Tronto (AP). The earthquakes of October 30 didn’t cause any victim but only some injured thanks to the fact that people was already evacuated and also because the Civil Protection was already present on the territory. Nevertheless, the impact of this seismic event was destructive; many small towns and villages, which have survived to the first earthquake, were heavily damaged. In the days following the earthquake of august 24 the Department of Civil Protection and RELUIS started the usability surveys by using the Aedes form (Italian acronym for “accessibility and damage during seismic emergency” [1]) which guides the inspector to rapidly assess the usability of a structure, including the description of damage and all the details of the building. The authors of this work, which formed the team of the Universities of Central Italy, visited a total of 127 structures in the period between the 25th of August and the 25th of October: 112 (88%) of them were schools, 3 (3%) were hospitals and sanitary buildings, 9 (7%) were civil and collective activities, 3 (2%) other structures. Excluded from this preliminary study are the architectural heritage buildings: because of the earthquake of the 26th of October it was not possible to collect enough data. The goals of this work are: Collect all the available informations on the inspected buildings by means of the creation of a Database with all the informations given by the Aedes Form, the comparison between the results of Aedes inspections and other informations, as the epicentral distance of the inspected building or the local intensity recorded by the seismic stations, providing quantitative results. The comparisons allow to state, for example, how many buildings were condemned in a certain range of epicentral distance, or to relate the observed damage with the seismic intensities.
