3. In-situ assessment of timber structures - Assessment methods and case studies
Abstract : In the assessment of timber structures, diagnostic investigations with reference to the condition and structural performance of these structures are necessary and often require appropriate health monitoring techniques. This thesis covers four aspects within the research area of the in-situ assessment of timber structures based on scientific knowledge and guidelines to perform assessment of existing timber structures:IDetermination of density of wood with portable X-rayThe mechanical performance of timber is often strongly related to the density of wood.
