“…While each step listed above was studied extensively by previous researchers [e.g., 19,22,25,27,35,45,48], the current research regards an aggregated and comprehensive framework comprising the different state of the art procedures of geometric data acquisition, 3D modeling, and structural analysis in a cohesive, consistent, and efficient fashion. In this regard, the novelty of the paper regards the effectiveness and the continuity across all steps which has not been previously established in the literature in a repeatable way for use by practitioners.…”

“…1), within the boundaries of Marches, Umbria, Latium and Abruzzi regions (Mazzoni et al 2018). The affected area experienced several earthquakes such as that of 1859 in Norcia (Marotta et al 2019), that of 1979 in Valnerina and that of 1997 in Umbria-Marches (Sorrentino et al 2018), which required restorations and interventions. Besides masonry and reinforced concrete ordinary buildings, Central Italy is characterized by a building portfolio rich of historical constructions, in fact as much as 4325 unreinforced masonry (URM) churches were inspected during the 2016-2017 seismic sequence (Penna et al 2018).…”

For both spiritual and cultural reasons, churches are an essential part of the historical heritage of several countries worldwide, including Europe, Americas and Australasia. The extreme damage that occurred during the 2016–2017 Central Italy seismic swarm highlighted once again the noteworthy seismic vulnerability of unreinforced masonry churches, which exhibited several collapses and caused uncountable losses to the Italian artistic heritage. The seismic performance of 158 affected buildings was analyzed in the aftermath of the main shocks. The failure modes activated by the earthquakes were identified making reference to the local mechanisms currently considered in Italy for post-seismic assessment of churches. The structural damage of the investigated buildings, related to 21 mechanisms rather than to an overall global response, was explained resorting to empirical statistical procedures taking into account ground motion intensity and structural details that can worsen or improve the seismic performance. Finally, parametric fragility curves were derived selecting those structural details that mostly influence the damage by means of the likelihood-ratio test. Developed models can be used in future territorial-scale scenario or risk analyses.

“…This set is used as a reference for describing damage in postevent surveys or vulnerability in a preventive analysis (Lagomarsino and Podestà 2004a, b). The methodology has been employed in several damage survey campaigns after the major earthquakes of the last decade: L'Aquila (2009, Mw 6.3) (Binda et al 2010;Da Porto et al 2012;Lagomarsino 2012;Brandonisio et al 2013), Pianura Padana (2012, Mw 5.9) (Indirli et al 2012;Sorrentino et al 2014;Valente et al 2017;Valente and Milani 2018a), and Central Italy (2016, Mw 6.2) (Carbonari et al 2017;Cescatti et al 2017;Borri et al 2018;Penna et al 2019;Sorrentino et al 2019). The method has been applied to earthquakes in other territories, e.g., in the Philippines (D'Ayala and Benzoni 2012) and in New Zealand (Marotta et al 2017), and it is currently under study in Québec.…”

Seismic response of a masonry church in Central Italy: the role of interventions on the roof

The seismic response of a medieval church in Central Italy is analyzed considering the two roof configurations, i.e., reinforced concrete and timber roofs, that the church had in different periods of its existence. Structural interventions and changes are common in the churches of this territory, where frequent earthquakes put these buildings at risk. The church studied here, St. Salvatore in Acquapagana (Serravalle di Chienti, province of Macerata), was damaged by the 1997 Umbria-Marche and the 2016 Central Italy earthquakes. Between these two seismic events, the church was repaired, and the concrete roof was substituted with a lighter timber roof. To investigate the influence of this change on the seismic response, a study was performed at the building and façade macroelement scales using the finite element model and rigid body spring model, respectively. For each approach, the two roof configurations were considered, and two strong motion records, from September 26, 1997, and October 30, 2016, were applied. The results show that the concrete roof improves the box-like behavior, but it increases the vulnerability of the masonry structures, characterized by a limited tensile strength. Conversely, in the timber roof configuration, the most vulnerable areas of the structure are the intersections between structural elements.
