Management of multi-source information to identify the typology of the horizontal structures in historical masonry buildings: the case study of the Museum of Capodimonte in Naples (Italy)

Abstract

The evaluation of the seismic safety of ancient masonry buildings usually requires compounding the need of preservation of the historical values with the need of achieving a proper level of knowledge of the parameters influencing their structural behaviour. To this aim, non-destructive techniques of instrumental investigation have lately attracted increasing attention, although the provided data are frequently not exhaustive and require to be integrated with different sources of information, such as historical documents and hypotheses of critical interpretation. Therefore, the management of this multi-source information is a crucial aspect in defining a methodological approach to the structural evaluation of the cultural heritage. This paper describes an integrated approach developed in the framework of the Project on the seismic evaluation of the Museum of Capodimonte in Naples (Italy) with reference to the typological identification of the horizontal structures upon the first level of the building. The management of the data derived from the application of the infrared thermography, integrated with the information from the visual inspections, the architectural survey and the historic analysis, has allowed obtaining a complete characterization of the structures under study.

TLS-Fem Integrated Structural Deformation Analysis on the Beamless Hall at Nanjing, China

“…Multi-source information is needed and non-invasive methodology is favored. A lot of research efforts have been devoted to this field, among which accurate geometric survey, numerical modeling and non-destructive testing (NDT) are employed owing to their non-invasive attributes (Maione et al, 2018).…”

Structural and seismic vulnerability assessment of the Santa Maria Assunta Cathedral in Catanzaro (Italy): classical and advanced approaches for the analysis of local and global failure mechanisms

“…n the last decades, in Italy many seismic events have highlighted that our buildings heritage is manly made of masonry structures that are highly vulnerable to damage and collapse events [1,2]. Moreover, the presence of many hazard seismic zones in the whole Italian country, has emphasized that diffuse operations and retrofitting are necessary to improve the seismic response of the existing buildings and to protect our cultural and historical heritage [3][4][5][6][7]. The seismic vulnerability assessment and the structural rehabilitation of the existing buildings are becoming very significant, especially for complex masonry structures of historical importance.…”

“…At that stage of diagnosis, infrared thermography is a novel and useful method for historic plaster and painted vaults. The management of the data derived from the application of infrared thermography, integrated with the information from visual inspections, the architectural survey and the historic analysis, allows a complete characterization of the historic plasters and painted masonry vaults to be obtained [11].…”
