From 3D Digital Documentation to Structural interventions for historic masonry structures

About the Project

Engineering problems related to conservation and restoration of Cultural Heritage are attracting increasing attention by researchers, offering opportunities for novel research and industry collaborations. Scotland’s historic environment is an essential part of its cultural background and economy but the effects of ageing, environmental conditions and past natural hazards have caused significant degradation, urging for action (Hyslop et al., 2006).

The development of digital technologies, such as terrestrial laser scanning, has already helped produce accurate representations of structures with applications in conservation, monitoring and Building Information Modelling (BIM) projects. The exploitability of laser scanning outputs, in the form of point clouds, is however still challenging though with respect to application for structural analysis of the built heritage. Recent developments refer to a variety of approaches for the reduction of 3D point clouds of complex structures (D'Altri et al., 2018) into models making use of advanced non-linear computational formulations based on the Finite Element Method (FEM) and Discrete Element Method (DEM), to facilitate and optimize capturing the mechanical behavior of historic masonry structures. This provides additional information for decision makers to ensure the maintenance, adaptability and resilience of existing masonry structures.

The aim of this PhD is to explore theoretical and procedural options for the development of highly accurate numerical models for structural purposes, linking 3D point cloud data to detailed modelling of masonry constructions. This innovative approach will incorporate current structural pathology and consider targeted on-site sensor measurements, to obtain semi-automated suggestions for future interventions. The outcome of this research is anticipated to offer an optimized decision-making route for structural interventions, reflecting the needs of a range of commonly encountered structural typologies and problems (Marinelli et al., 2019), with direct applicability to historic masonry structures in Scotland. It will revolutionise practice for directly benefitted external practice for directly benefitted external stakeholders, especially those responsible for the care of masonry structures of significant heritage value, by informing the design, improving the structural monitoring and leading to targeted interventions as needed.
