Cultural Heritage and Earthquake: The Case Study of “Santa Maria Della Carità” in Ascoli Piceno

Abstract

Background:In October 2016, two major earthquakes occurred in Marche region in the Centre of Italy, that resulted in widespread damage. The second one strokes Norcia, Visso, Arquata del Tronto, Accumoli and Amatrice, causing a lot of damages to cultural heritage of the cities of Tolentino, San Severino, Camerino and Ascoli Piceno, where the church ofSanta Maria della Caritàis located.Introduction:The church has high historical, architectural and social value for the city of Ascoli Piceno, because it is the only one that is opened to the devotees all time in the day and night. From the structural point of view, the church has a long and important annex to the north, which was later built with respect to the church, and after the L’Aquila earthquakes (2009) damages, the church was subjected to a retrofit intervention, in order to obtain a better “box-like behavior”.Objective:This paper addresses how the relevant annex influenced the seismic response of this historical complex and how, more generally, this kind of asymmetric mass may affect the behavior of historic churches.Results and Conclusion:The results indicate that the presence of annex plays a significant role in the dynamic response of the church and affects the distribution of damages in the whole building. The results of the seismic simulation agree with the observed damage.

From TLS to Fe Analysis: Points Cloud Exploitation for Structural Behaviour Definition. The San Ciriaco’s Bell Tower

“…Limit analysis methods have been frequently applied in order to investigate the collapse mechanism of masonry structures subjected to given load distributions. Smeared crack approaches and/or damage models may be used to simulate the local loss of strength masonry material suffers when it enters the nonlinear behaviour (Clementi et al, 2017). However, to the best of the authors' knowledge, the numerical analysis itself is still very demanding, especially when dealing with large and complex structures.…”

Dynamic Behavior of an Inclined Existing Masonry Tower in Italy

“…A major research field in structural engineering concerns the structural safety and seismic assessment of the masonry buildings, especially historic structures, to preserve their main architectural features in the cultural heritage (Roca et al, 2013). In the last few decades, a significant number of structures was severely damaged, especially monumental buildings, churches and belfries, by the most recent Italian earthquakes such as Umbria-Marche 1997-1998, Abruzzo 2009, Emilia-Romagna 2012, Central Italy Earthquake 2016 (Lagomarsino and Podestà, 2004;Brandonisio et al, 2013;Milani, 2013;Clementi et al, 2017).…”

Sustainable Fruition of Cultural Heritage in Areas Affected by Rockfalls

“…Every year, natural disasters cause loss of life and damage to property, including heritage sites, as well as damage to the environment [3][4][5]. The most remarkable natural events usually threatening the fruition of such areas are earthquakes (e.g., [6][7][8]) and landslides (e.g., [9][10][11][12][13]). These two phenomena can be often associated, as a seismic event can be considered a trigger of landslide movements [14][15][16][17][18][19].…”
