Structural Model Updating of a Historical Stone Masonry Tower in Tønsberg, Norway
Conservation of historical structures plays a pivotal role in every nation, and numerical modeling of historic buildings is an essential part of a conservation methodology. Since deriving the mechanical properties of construction materials using destructive tests is usually not allowed, and most of the cultural heritage assets are so complicated in architecture, numerical modeling of historic buildings is challenging for the analysts. Therefore, in this study, a non-invasive approach for numerical simulation of historic structures has been proposed and applied on a historical stone masonry tower (Slottsfjell tower) in the city of Tønsberg, Norway. Two types of sensors were utilized for finite element modeling of the stone masonry tower. Firstly, three-dimensional (3D) laser scanners were used as a fast and precise tool to provide a finite element model of the case study with and without considering soil-structure interaction. Secondly, operational modal analysis (OMA) was performed using accelerometers to derive the tower’s dynamic characteristics. Finally, as a preliminary result of the case study in the context of a European project, the produced finite element models’ mechanical properties are updated based on the OMA results, and the effect of considering soil-structure interaction has been investigated.
