Abstract
The critical analysis of the possible consolidations, conducted from the perspective of compliance with the principles of restoration and structural safety, arises as a necessary phase of the intervention project on historical masonry structures. The Church of Santa Maria Incoronatella della Pietà dei Turchini in Naples is a specific case on which a restoration was conducted: an original structural analysis program, based on an interpretive model in line with the actual static behaviour of masonry, is applied to better understand the crack pattern and verify the efficiency of a structural improvement aimed to mitigate the effects of a foundation settlement.
