“…The results show that in most of the cases the real damage is reproduced faithfully. This capacity is also shown in other papers as [21,22]. The main results of Santissimo Crocifisso church are reported in Figure 6, where a good comparison between the real and the numerical damages is summarized for the South and the West façades.…”

This study presents a detailed failure analysis of different masonry churches, which were severely damaged during the 2016 Centre of Italy seismic sequence, using nonlinear (i.e., kinematic limit and pushover) analyses. The main aims of the numerical investigations are: (i) to carry out a sufficiently wide sensitivity study on different specific case studies to have an insight into the role played by the geometrywhich is always unique for churchesand by the irregularities; (ii) to validate or address the limits of applicability of the most widespread conventional static approaches recommended by Italian Code.

“…he damage assessment of historical masonry buildings is one of the most difficult tasks to accomplish in structural mechanics, since this kind of structures is commonly heterogeneous, with complex geometries, irregularities and absence of a box behaviour due to defective connections between different structural parts, in particular walls and floors, that often play a fundamental role. However, the knowledge of the dynamical behaviour is crucial for a reliable seismic vulnerability assessment, which became more and more important due to recent catastrophic earthquakes that stroked Italy in the last few decades (Umbria-Marche 1997-1998, Abruzzo 2009, Emilia-Romagna 2012, Marche-Lazio-Umbria-Abruzzo 2016) [1][2][3][4]. Towers and belfries are peculiar structural type which characterizes Italian architectural heritage.…”

The dynamic behaviour and the seismic vulnerability of the ancient civic clock tower of Amatrice, dramatically damaged by the last shocks sequence of 2016 that occurred in Central Italy, is studied in this paper by means of advanced 3D numerical analyses with the Non-Smooth Contact Dynamics Method (NSCD). Thus, a discontinuous approach was used to assess the dynamic properties and the vulnerability of the masonry structure, through large displacements regulated by the Signorini's law, concerning the impenetrability between the rigid bodies, and by the Coulomb's law, regarding the dry-friction model. Afterward, different values were assigned to the friction coefficient of the models and real seismic shocks were then applied in nonlinear analyses. The major purpose of this study is to highlight that relevant data on the real structural behaviour of historical masonry may provided through advanced numerical analyses. The comparison between the results of numerical simulation and survey of the existing crack pattern of the bell tower

The Non-Smooth Contact Dynamics method (NSCD) has been applied to the study of the seismic response of different belfries inside the epicentral zone of the last Centre Italy earthquakes of August and October 2016. According to this model, the masonry towers have been modelled as a system of rigid blocks, and since the contacts between blocks are governed by the Signorini's impenetrability condition and by dry-friction Coulomb's law, the towers exhibit discontinuous dynamics. The NSCD method has proved to be a powerful tool for investigating the dynamics induced by ground seismic accelerations. Indeed, the numerical results have given a deep insight into the seismic vulnerability of these damaged towers, confirming several possible failure mechanisms.
