Preserving cultural heritage (CH) sites and monuments is essential to safeguard them from natural hazards, environmental degradation, and the effects of aging. Finite element (FE) modelling is a key tool for the structural assessment of cultural heritage sites and monuments. Geoinformatics, traditionally used in other fields, is now increasingly used in numerical modelling, offering significant potential for enhancing structural assessment. This paper presents the integration of FE modelling and geoinformatics for the structural assessment of a monument at an UNESCO, CH site in Cyprus. The collaboration between these two fields enhances the reliability of structural assessments. A comprehensive 3D model was developed in SAP2000 using data from terrestrial laser scanning, UAV and terrestrial photogrammetry, 360° imaging, and handheld photography. The resulting high-resolution, textured mesh was used to derive accurate geometric information for FE model development. The geometry was simplified and converted into a solid model to allow computationally efficient meshing and analysis. Preliminary modal analysis identified key vibration modes, including those influenced by an existing fracture. This model will be calibrated using data from ongoing non-destructive tests (NDT) and dynamic testing, enabling further simulation of structural scenarios such as seismic events. This interdisciplinary approach that is scalable and adaptable to similar heritage sites, improves the reliability of structural assessments and supports informed decision-making for CH conservation.

摘要

Preserving cultural heritage (CH) sites and monuments is essential to safeguard them from natural hazards, environmental degradation, and the effects of aging. Finite element (FE) modelling is a key tool for the structural assessment of cultural heritage sites and monuments. Geoinformatics, traditionally used in other fields, is now increasingly used in numerical modelling, offering significant potential for enhancing structural assessment. This paper presents the integration of FE modelling and geoinformatics for the structural assessment of a monument at an UNESCO, CH site in Cyprus. The collaboration between these two fields enhances the reliability of structural assessments. A comprehensive 3D model was developed in SAP2000 using data from terrestrial laser scanning, UAV and terrestrial photogrammetry, 360° imaging, and handheld photography. The resulting high-resolution, textured mesh was used to derive accurate geometric information for FE model development. The geometry was simplified and converted into a solid model to allow computationally efficient meshing and analysis. Preliminary modal analysis identified key vibration modes, including those influenced by an existing fracture. This model will be calibrated using data from ongoing non-destructive tests (NDT) and dynamic testing, enabling further simulation of structural scenarios such as seismic events. This interdisciplinary approach that is scalable and adaptable to similar heritage sites, improves the reliability of structural assessments and supports informed decision-making for CH conservation.
