Integrated geophysical and mechanical study on the wooden structures of the ceiling of the Church of Beata Vergine Maria Assunta in Cielo

Non-destructive testing by mean of ground penetrating radar were performed on the wooden elements constituting the roofing of the Cathedral of Foggia. These measurements were related to the restoration work of the roof. Measurements campaign aimed at the assessment of the conservation status of the wooden elements of the all major and secondary elements of the truss of the nave, as well as on those main of the dome and the apse. Results show various abnormalities which correspond to nodes and/or slots. The presence of the nodes allow a rapid and accurate analysis of the electromagnetic waves velocity and the volumetric water content.
