== Abstract ==

The seismic events occurred in Italy in the last decay (L’Aquila 2009, Emilia
2012, Central Italy Earthquakes 2016/2017) have caused the collapse of numerous historical
buildings and monuments with loss of life and irreversible damages to the cultural heritage.
An effective seismic prevention would avoid, or delay, the most frequent collapse
mechanisms. However, it requires a correct interpretation of the structural mechanical
behavior. With regard to the traditional masonry buildings, this issue presents a high level of
complexity due to the uncertainties related to the materials and the constructive techniques.
Furthermore, historic buildings are often the result of several modifications that induce
significant structural irregularities. A possible analysis strategy is provided by a discrete
macro-element modelling (DMEM) approach which is able to simulate the global behavior of
traditional fabrics, if supported by an adequate level of historic, geometrical, constructive
and structural knowledge. In this paper a multidisciplinary procedure is applied to the church
of S. Sebastiano in Regalbuto (Italy), considered as case study. This procedure is composed of
three steps: the knowledge phase in which the constructive apparatus and the static schemes
are identified, the modelling phase and the assessment phase in which the current safety level
of the building and possible interventions that would be compatible with its cultural instance,
are individuated. According to the followed procedure, different scenarios of intervention,
characterized by increasing levels of benefit and invasiveness, are considered. For each
scenario, non-linear static push-over analyses are performed, to evaluate the benefits and
identify the structural critical issues, useful to individuate the next scenario. The obtained
results are presented and discussed both in terms of capacity curves and failure mechanisms.
