X-Ray technology for the assessment of timber structures

For the assessment of timber structures, which is a permanent task to evaluate the normal function, nondestructive testing methods are preferred but the value of the information is limited due to the performance of the applied method. X-Ray is a non-destructive technology which allows a view into the structural member, where especially internal damages like cracks, holes or plastic deformations of mechanical fasteners can be detected. The mobile X-Ray technology is a non-destructive testing method with a good accuracy for detailed information. The digital analysis of the radiograms allow in-situ measurements. The method and its possibilities for nondestructive testing of timber structures are presented. The presentation based on practical examples gives an overview of the ability and the limits of this method. It shows that the mobile X-Ray technology offers a high potential for an effective assessment.
