Abstract
Abstract. This research aims to propose a classification of masonry typologies in Central Italy after the earthquakes that in 2016 involved about 120 municipalities. This territory, since several decades, presents high fragility features due to the depopulation process that increase the vulnerability and risk degree. This condition affects even the maintenance practices of traditional buildings by the inhabitants and the extraordinary post-traumatic situation acts as an accelerating factor of the abandonment. In this article we will explain deeply the first part of the research, focusing in particular on methods and tools that were defined and used to carry out this study. The research highlights the need of a specific comparative tool for masonry facades classification. This was elaborated through the comparison of existed bibliography as the EMS-98, the Aedes schedules and the local classification by Umbria Region and the De Meo book. The result then is the production of another synoptic map that would simplifies the correlation between different approaches to classification and the censed facades. Moreover, it was elaborated a second synoptic map moving from the analyses of many survey forms already discuss in literature. The result of this comparison is a new survey form to carry out the field research on vernacular masonry buildings. This new form focuses on the characteristics of the buildings that the research aims to study in Central Italy. The two tools that are illustrate in the following paper were applied on one hundred survey of masonry buildings carried out during August 2018. The last part of this paper proposes a statistical analysis of the results of the field research.
Highlights
AND METHODOLOGYThe seismic events that in 2016 hit a large area of the Apennine Mountains in Central Italy, concerned about 8000 km2 of territory, including 138 municipalities in 4 different regions: Marche, Umbria, Lazio and Abruzzo (Ingv.it)
The field research started in June 2018 and ended in September
It was possible to elaborate and outline which areas are characterized by a similar masonry and which instead are extremely different (Braucher, Currà, 2018)
Summary
The seismic events that in 2016 hit a large area of the Apennine Mountains in Central Italy, concerned about 8000 km of territory, including 138 municipalities in 4 different regions: Marche, Umbria, Lazio and Abruzzo (Ingv.it). An astonishing amount of contemporary and historical buildings were damaged during these events (Hofer et al 2018). For this reason, during the emergency phase, the technicians involved filled out 219.061 Aedes forms (Protezione Civile, 2010) and Fast forms. 30% of the buildings resulted in deeply affected and condemned. This earthquake hardly affected the daily life of 600.000 inhabitants of the Central Apennine Mountains (Ingv.it). The quakes took place between August 2016 and January 2017 (Sorrentino, et al, 2018)
