In the field of heritage conservation and preservation, the integration of digital tools has transformed the approach to management, maintenance and renovation of existing buildings. Digital Building Logbooks (DBLs) and Digital Twin (DT) technologies have the potential to support the assessment and the monitoring of structural performance, in order to identify vulnerability and to enable better decision making throughout the building lifespan. In this study, a framework is proposed for developing structural DTs to monitor the dynamic behavior of heritage buildings. The framework initiates with data gathered from DBLs and encompasses the generation of Heritage Building Information Models (H-BIM) derived from digital surveys. Subsequently, three-dimensional finite element models (FEM) are generated and calibrated. This approach addresses the challenges associated with interoperability, particularly those related to the reproduction of complex geometries, the assignment of material properties and the generation of accurate shells for the development of FE models. Finally, the possibility to derive analytical response surfaces reproducing the dynamic behavior of the building is investigated in view of quantifying uncertainties, evaluating sensitivities and monitoring changes in the predicted behavior. The proposed methodology will be illustrated with reference to a significant case study, Palazzo Poniatowski-Guadagni, a 18th-century masonry building in Florence. The resulting digital twin will be integrated into the BUILDCHAIN system, which seeks to illustrate the advantages of utilising innovative digital building logbooks for the effective management and preservation of cultural heritage.

摘要

In the field of heritage conservation and preservation, the integration of digital tools has transformed the approach to management, maintenance and renovation of existing buildings. Digital Building Logbooks (DBLs) and Digital Twin (DT) technologies have the potential to support the assessment and the monitoring of structural performance, in order to identify vulnerability and to enable better decision making throughout the building lifespan. In this study, a framework is proposed for developing structural DTs to monitor the dynamic behavior of heritage buildings. The framework initiates with data gathered from DBLs and encompasses the generation of Heritage Building Information Models (H-BIM) derived from digital surveys. Subsequently, three-dimensional finite element models (FEM) are generated and calibrated. This approach addresses the challenges associated with interoperability, particularly those related to the reproduction of complex geometries, the assignment of material properties and the generation of accurate shells for the development of FE models. Finally, the possibility to derive analytical response surfaces reproducing the dynamic behavior of the building is investigated in view of quantifying uncertainties, evaluating sensitivities and monitoring changes in the predicted behavior. The proposed methodology will be illustrated with reference to a significant case study, Palazzo Poniatowski-Guadagni, a 18th-century masonry building in Florence. The resulting digital twin will be integrated into the BUILDCHAIN system, which seeks to illustrate the advantages of utilising innovative digital building logbooks for the effective management and preservation of cultural heritage.
