This paper describes the studies conducted to assess damage in a sculpture. These include a numerical model and an ambient vibration test based on a dense mesh of points to identify the fundamental natural frequencies and the corresponding modal shapes. From the comparison between identified and calculated modal parameters, it was possible to identify a region of inflexion of curvatures of the second-order vibration modes at a particular location that was associated with a local fragility of the structure. A posterior removal of the cladding evidenced a highly degraded area at this location.
