Abstract

The development of digital technologies has already supported the production of accurate representations of structures, with applications in conservation, monitoring and Building Information Modelling projects. The exploitability of their outputs remains particularly challenging with respect to applications for structural analysis of historic structures. This paper investigates the use and potential of 3D laser scanning output for structural engineering applications and suggests a semi-automatic, user-friendly approach to building 3D finite element models utilizing point cloud data. Compatible computational techniques offered by commercial software are investigated, with findings applied to the case study of the 6m-high freestanding masonry tusk of Spynie Palace, Scotland. The structural response of the tusk is studied under critical load combinations that lead to stress patterns confirming the location of vulnerable areas with visible signs of deterioration on the real structure. Further research is identified with a view towards adapting the methodology to suit the needs of structural typologies and the nature of structural problems commonly encountered in properties in the care of Historic Environment Scotland.
