== Abstract ==

Over the past few decades, the conservation and seismic assessment of historical
buildings has gained great importance. In particular, the prediction of the dynamic response
of masonry constructions plays a central role in retrofitting and conservation interventions.
Finite element modelling has become the most common and accessible approach to study the
behavior of complex masonry structures, however, the gap between numerical and
experimental analysis may lead to erroneous results.
This work describes the model updating procedure applied to the finite element model of San
Giovanni’s church in Macerata, condemned in October 2016 after the Central Italy
Earthquake. The laboratory of Proof and Research on Structures and Materials of Roma Tre
University carried out an extensive in-situ testing campaign including geometric survey, video
endoscopy, flat-jack test, sonic tomography and ambient vibrations test in order to investigate
the state of the building. The work involved both numerical and experimental analysis: the
results of the testing campaign were interpreted and correlated with an accurate finite element
model developed with the software Midas Gen. Operational modal analysis was performed in
order to extract the modal parameters of the building (modal frequencies, shape vectors and
modal damping). Material characteristics and boundary conditions were updated according to
the Douglas-Reid method. In the end, the final model was compared to the initial model to
evaluate and discuss the process.
