Non-destructive inspection of a historical wooden structure damaged by fire

Abstract eng:
In 2004, timber structures of the 15th century Castle Pernstejn were investigated by non-destructive methods that included acoustic waves, dendrochronology and resistance drilling. In the spring of 2005, a fire destroyed a corn-loft of the castle and only horizontal floor beams had remaining loadbearing capacity. The same sets of in-situ experiments of the identical members to those tested in 2004 were performed after the fire and the results have been compared to the previous ones.
