Abstract Considering the high vulnerability of existing structures and infrastructures, mainly due to deterioration of building materials, to the exposure to cyclic and seismic loads and environmental factors, one of the main challenges of recent years in the field of structural health monitoring is the development of systems capable of integrating satellite data with on-site sensor measurements in order to obtain more reliable information on structural safety conditions for the structures at different scales: from the local to the territorial one. However, this enormous potential is counteracted by some limitations of the common satellite techniques used to obtain displacement along the LOS (line of Sight) that can lead to the loss of information in the case of particular flexible infrastructures, as confirmed from recent studies. The bridge "Ponte della Musica Armando-Trovajoli" in Rome, made by a steel arch structures with a underlying prestressed concrete deck, considered as case study in this work, represents an example in which the satellite images do not allow to obtain useful information on the displacement, at least for the central and more deformable portion of the deck, and therefore also on the possible pathological movements. In the attempt to interpret of this phenomenon, this paper focuses on a dynamic identification campaign carried out on the bridge using ambient vibration measurements, to suitably calibrate a SAP2000 3D structural numerical model of the bridge to be considered for successive numerical evaluation of thermal deformations useful to better understand the link between physiological deformations and limits of satellite techniques. © 2022 The Authors.
