Procedures used to detect the condition of timber in historical structures
Kloiber, Michal
Within the scope of the lecture, methods of structural and technical surveys and their use were presented. The need for this kind of diagnostics, its significance for design projects, and various forms of survey outcomes were discussed, such as identification of tree species, identification of damage type, a detailed evaluation of moisture content in wood, identification of biological damage scope, and evaluation of damage degree.
How to repair decayed historical timber constructions using all-wooden lap joints
Kunecký, Jiří
Most common issue when some moisture or insect- induced decay is present in historical timber structures is the use of lapped scarf joints. This technology keeps the look of the original construction, the decayed part is removed while keeping the healthy wood in the structure. The work presents the guidelines written for the purpose during four years of intensive research activities. The guidelines describe experimental results but also results of numerical and mechanical models. It is intended to be valuable for structural engineers, carpenters and workers of the cultural heritage institutes. The technology is suitable for repair of valuable historic timber structures.
