摘要
The paper focuses on an interdisciplinary research project concerning the preservation of the XVII century monumental building of Monte di Pieta in Naples, Italy. The building underwent a series of restorations being the structural walls affected by humidity and cracks. The importance of this monumental building in the historical city center of Naples led to design an extensive surveying program to provide the designers of strengthening with a detailed investigation of the geometry of the entire structure, and particularly of the entrance facade, with great details on several materials, thicknesses and restraints. A preliminary investigation was performed on the historical phases of this monumental building to have a clear knowledge of its vicissitudes, and then in situ structural assessment included 3D laser scanner techniques probing radar, in situ stress measures. This surveying phase was crucial especially for the subsequent Finite Elements modeling ( F. E. M.) of the facade. The scope of the numerical re. ned analyses was to evaluate the state of stress in the structural elements of the facade putting in evidence structural `weak points' and. nally to design a retrofit intervention having a detailed map of the `intervention areas'. The theoretical damage assessment has been compared with on-site assessment and in situ stress measures. The damage primarily concerned the entrance facade and its valuable decorations. Furthermore, the basic principles for the design of the strengthening have been discussed.
