Diagnostics of the technical condition of timber roof frames using Fakopp 3D Sonic Tomograph

Abstract

The Fakopp 3D Sonic Tomograph is used in practice for making the diagnosis of latent, i.e. internal, damage to living trees. We experimented with the possibility of using this device for decay detection in timber elements of a roof frame. It was tested in the laboratory (in labo) as well as in the roof space of a historical truss (in situ). We examined the timber elements of historical wooden trusses that had relatively a small diameter.
