Knowledge is fundamental to understand the key characteristics of a heritage building.
Furthermore, constructive analysis of a historical construction is central to research into its structural
behavior. This work aims to increase the knowledge level of a historical construction by the understanding of
the constructive evolution through Historical-Building Information Modeling (H-BIM) workflow. The research
proposes a multidisciplinary approach applicable to the field of historical constructions, which is resumed
in the followings steps: historical-critical analysis, material and soil characterization, data organization
through H-BIM, qualitative static and dynamic structural analysis, validation of the results. The building of
Quartel da Tropa – located in Florianópolis, Brazil – is used as a practical case study to show how the proposed
research can be adapted to historical buildings. Such an impressive eighteen-century masonry construction is
the largest troop barracks among Brazilian fortifications. The proposed approach allows the creation of
a structural model from the architectural model with fewer uncertainties and less simplification, improving
the knowledge path of historical constructions and its structural assessment. The historical-critical analysis
and the H-BIM allow managing and presenting of the information useful to the understanding of the constructive
phase evolution of a historical building.
The assessment of Cultural Heritage buildings is a challenging multi-disciplinary activity, involving different tasks. The paper exemplifies the application of the methodology involving historic and architectural research complemented by a dynamic survey in the structural modelling of the Galleria degli Antichi, a monumental building built in the 16th century in the historic town of Sabbioneta (Italy), which is included in the UNESCO World Heritage list since 2008. After a concise historic background on the investigated building, the paper focuses on the results obtained from operational modal testing and the subsequent finite element (FE) model correlation analysis. The good knowledge of the structural geometry and the large number of identified vibration modes, combined with a classic system identification technique, allowed to establish a linear elastic FE model, accurately fitting the modal parameters of the monument in its present condition.
The paper exemplifies the application of the methodology involving historic and architectural research complemented by HBIM and operational modal testing in the structural modelling of a heritage palace, the Galleria degli Antichi in the historic town of Sabbioneta (Italy), included in the UNESCO World Heritage list since 2008. This monumental building was built in the 16th century. Full details on the history of the building and the information obtained in the nondestructive survey are given in the paper. The good knowledge of the structural geometry, along with the complete inspection carried out and the large number of identified vibration modes, allowed to establish a numerical model of the monumental building for a first quantitative assessment of its structural condition.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
