This paper presents the development of an accurate digital twin of the 100 m-tall Atmospheric Observatory tower, a steel truss structure located at the EC Joint Research Centre (JRC) in Italy. The study aims to address uncertainties in material properties and boundary conditions for structural models. Wireless accelerometers were used for continuous vibration monitoring at different levels of the tower. Operational Modal Analysis (OMA) techniques were applied to identify the tower’s dynamic parameters, and a Finite Element (FE) model was developed to provide deeper insights into the structural behavior. Model updating techniques were employed to minimize discrepancies between the FE model and the measured dynamic parameters. The updated numerical model accurately captures the tower’s dynamic behavior, emphasizing the importance of model updating for enhancing the accuracy of digital twins. This work highlights the role of digital twins in structural health monitoring and predictive maintenance strategies for complex structures.
