Abstract
This paper discusses an approach for identification of historic buildings that combines Terrestrial Laser Scanning (TLS) survey, Deviation Analysis (DA) and Finite Element (FE) numerical modelling. The methodology is presented through the application to an illustrative case study: an early medieval period brick minaret located in Aksaray (Turkey). Precise direction of inclination, leaning angle, local deviations from circular building shape, deflections from vertical planes, local curvatures and related maps were obtained with high accuracy by DA, based on detailed point cloud 3D mesh model. In addition, differently from traditional approaches in FE analysis, a method for direct transfer of high accuracy TLS based 3D model to FE structural analysis is introduced. The FE model is subsequently employed to interpret and verify structural health of the historic building.
Highlights
The process of preservation of architectural heritage introduces different issues concerning documentation, conservation, restoration and reusing activities: it needs specific analyses based on accurate broad-spectrum surveys
Mesh models used in Finite Element (FE) analysis are generally created in a CAD software and they cannot be strictly considered as “reality based” 3D models since they come from a manual user-performed remodelling approach
This paper discusses these issues presenting an approach for identification of historic buildings that combines Terrestrial Laser Scanning (TLS) survey, Deviation Analysis (DA) and Finite Element (FE) numerical modelling
