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.
The influence of the change of moisture content of timber on its physical-mechanical properties
Dziadková, Aneta ; Anton, Ondřej (referee) ; Heřmánková, Věra (advisor)
This bachelor thesis determines mechanical and physical properties of timber in different state of water absorption. Three sets of samples will be used to define their density, dimensional and volume swelling ratio, compressive strength and bending tensile strength. As an evaluation, properties obtained from testing will be graphically illustrated depending on moisture content.
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.
