The Existing Timber Structures – Possibilities and Limits of Diagnostic Methods in Assessment Process

The wood is traditionally been applied as the building material in building and bridge construction. The number of applications of wood in building structures increases in recent years. According with this trend, the emphasis is on the development of diagnostic and monitoring methods for existing wood structures. In the paper, published results of a survey of existing wood structures in relation to the evaluation of qualitative and quantitative characteristics of the investigated structures. There are finally discussed the possibility to reproduce the results of non-destructive measurement relative to evaluate the strength characteristics of wood.
