Abstract: In the absence of appropriate maintenance intervention, the degradation of wood along with factors such as timber quality, carpenter accuracy, and lack of maintenance, all damage the structural integrity and serviceability of timber structures. Historic timber structures, as part of our cultural heritage, should be preserved when possible. This aim should be addressed by architects and technicians, who are responsible for building conservation. In this paper, a method to assess old timber structures is proposed. It is a method based on the analysis of data gathered systematically at the building site regarding the characteristics of the wooden structural elements. This method has been developed from scientific research and building site inspections. The authors have developed a R&D&I Project, (Ministerio de Fomento, Spain, 2004), to apply NDT to the evaluation of timber structures, with a visual inspection to be performed by qualified site surveyors using a minimum of destructive testing to determine parameters and obtain conclusions of the structural elements mechanical characteristics.
Instrumental techniques applied in situ are micro drilling, ultrasonic and wood hardener. NDT techniques allow researchers to save time in diagnosis and minimize damage to the sound timber. These methods may also be applied for monitoring the condition of historic timber structures, obtaining data on the building at inspection points (marked on the surface of the members), and other critical parts of the structure.
