The Influence of the Human Factor on the Measurement Results Acquired by Using the Resistance Drilling Device RinnTech Resistograph R650-EA
Dziadková, Aneta ; Heřmánková, Věra ; Anton, Ondřej ; Szórád, Martin
The diagnostics of wooden structures using the detection drill RINNTECH Resistograph R650-EA is one of the popular semi-destructive methods. This article deals with the issue of the influence of the human factor on the measurement results. The recommended testing direction is the radial direction, perpendicular to the grain. However, the desired direction is sometimes difficult to maintain. The experiment takes into account three different factors that may occur during the testing. The goal is to determine to what extent the human factor affects the measured results. Thanks to the conducted research, it was found that gradual tilting of the device during measurements influences the measurements most significantly.
Evaluation of the condition of structural wood using resistance drilling with the Rinntech RESISTOGRAPH detection drill
Szórád, Martin ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
The theoretical part of the thesis focuses on a basic overview of wood properties, damage, protection and used diagnostic methods. In the practical part, it focuses on the comparison of selected physical and mechanical properties with the resistance characte-ristics obtained from resistance drilling. Finally, a design calculation is performed using the results from the measurements in the practical part.
Evaluation of the condition of structural timber using resistance drilling technology
Dziadková, Aneta ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
The aim of this master thesis is to summarize the overview about characteristics and properties of timber and about diagnostic methods used for timber structures prospecting. Experimental part is focused on comparison of drill resistance measurement using Rinntech RESISTOGRAPH for samples at different moisture levels. This paper also includes building survey of roof truss of Litomyšl‘s library and structural report of rafter.

Hodnocení stavu dřeva prvků krovu kostela sv. Jakuba v Brně pomocí resistografu s vyhodnocením míry jejich poškození
Hapala, Jakub
Presented diploma thesis evaluates current state of wooden parts of timber roof truss of Saint James´ church in Brno using Resistograph 4453. The aim of presented diploma thesis is to discover internal defects of structural framework caused by wood-destroying insects and rotting, determination and exact inspection of the extent of biotic damage. For those purposes a method of resistance drilling was chosen. After a complete evaluation of the measured values, the results were marked in the drawings and enrolled into tables. The degree of damage of each part was stated in separate tables. Within remedial measures it was determined whether to maintain or replace parts of the structural framework.
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.
Comparison of Acustic Method and Drill Resistence Measurements of Timber on Medieval Beams
Kloiber, Michal ; Kotlínová, M.
The summary of selected experimental methods is presented, which were used for studying properties of damaged historic timber. In 2004, the late mediaeval fir beams in the store houses of the 15th century Castle Pernstejn were evaluated.
