Abstract: In the present paper, results are presented from the postprocessing of ambient vibration measurements at a mill building. The mechanical properties of the structural elements were estimated through these records. It was found that the eigen-properties of the final structure are not significantly altered due to the simultaneous increment of the mass and the stiffness of the building. The in situ measurements document that both the added and the existing structural elements cooperate in the carriage of the applied loads. It was additionally found that, as a result of the operation of the mechanical equipment, the structural system of building is significantly vibrated. Therefore, it is proposed that the use and operation of this equipment for display purposes should be limited. Finally, the need for a re-examination of the structure in the near future is also proposed, as it is necessary for the certification of the sustainability of the interventions.

Keywords: ambient vibrations; mass addition; stiffness addition; eigen-properties; influence of interventions; monument; mill.
