Reconstruction of Historical Timber Roofs at Žehušice Castle

Abstract:

The paper presents some aspects of the reconstruction of timber roofs at Žehušice Castle. The roofs were built at different times and using various types of structural systems. Many timber elements of the roofs have been heavily damaged by previous unprofessional alterations to them, or, more often, by neglected maintenance and subsequent fungal attack caused by massive leaking. Because of the requirements of the National Heritage Institute it was necessary to be sensitive to the existing structures and minimize changes to them during the reconstruction of the roofs. In order to successfully achieve this, it was necessary to understand the distribution of stresses in the structure and its static behavior as well as possible. Therefore, 3D computational models were developed. On the basis of the obtained results, it was decided whether roof elements would be replaced or only parts of them. However, the informative value of relatively complicated mathematical models appeared to be limited.
