Numerical F.E.M. refined analyses of the façade of Monte di Pietà in Naples, Italy: analysis of the damage evolution

The purpose of the work presented in this paper is to perform a preliminary investigation on the historical phases of life of the monumental building of Monte di Pieta in Naples (Italy), in order to have a clear knowledge of its vicissitudes and to provide quantitative details for assessing the actual in situ condition through numerical Finite Elements modeling (F.E.M.) and where necessary to design the appropriate retrofitting interventions based on a detailed map of the "damaged areas". The scope of the numerical refined analyses is to evaluate the state of stress in the structural elements of the facade putting in evidence structural 'weak points'. The numerical damage assessment has been validated by means of comparisons with in situ assessment and stress measures. The damage primarily concerned the entrance facade and its valuable decorations. The cracking pattern is clearly visible especially on the architrave of the portal and on the central window and the curvilinear tympanum above.
