Hodnocení stavu dřevěných prvků krovu kostela sv. Jakuba v Brně pomocí ultrazvukové metody s vyhodnocením míry jejich poškození
 Dvořák, Radomír
This final work deals with the evaluation of a truss structure and its wooden elements of St. James church located in Brno. The building is enrolled to the list of a National cultural monuments. The aim was to detect the damage done as well as to determine its range to particular elements. The evaluation of a truss was based on a survey made by sensoric and instrumental methods. Two devices were used for these measurements - Arborsonic Decay Detector and Fakopp UltraSonic Timer at which the spike and cylindrical sensors were used. To compare and determine the conformity or differentiation of the above said ultrasonic devices were used statistical analysis of the results. The structure was found infested with wood decaying insects and wood-destroying fungi mainly in tie beams, collar ties and pentagonal purlins. This damage was evaluated and the level of damage was determined together with its range. The result was recorded in drawings (top view plan). This drawing together with other results will serve as a basis for further phase of reconstruction which is planned to be made to this historically valuable structure.

Utilisation of non-destructive and gentle instrumental methods during research of wooden construction of historical buildings
 Frankl, Jiří ; Kotlínová, M. ; Kloiber, Michal
The basis of research of wooden constructions of historical buildings is the evaluation of their condition with use of sensorial methods. In cases when some parts of constructions are fully or partially inaccessible and in cases when we want to get deeper knowledge about their qualitative and mechanical condition, it is necessary to use other instrumental methods.
