Utilization of accelerated durability test of wood glued joints for consequent service-life prediction
Šmíra, David ; Tupý, Michael (referee) ; Vaněrek, Jan (advisor)
The aim of my diploma thesis are methods which are able to describe durability aspects of glued wooden joints. The main objective are methods which primarily includes hygrothermal stress acting in the glued joint of wooden adherend and determine the service life of the specific glued joint by modelling based on Arrhenius relation and the other methods. Other part of this work is aimed to shear tests of the samples exposed to different thermal and humidity conditions and for individual sets of exposures determining the glue penetration depth into the wooden adherend by EPI fluorescent analysis. These analytic methods are used for quality check of the glued joints, which are mostly based on strength, chemical or structural parameters of the tested sample.
Experimental Research in the Field of Glue Laminated Elements on the Basis of Climate Tolerant Deciduous Trees
Šuhajdová, Eva ; Straka,, Bohumil (referee) ; Kanocz,, Jan (referee) ; Pěnčík, Jan (advisor)
This Doctoral thesis is focused on research of usability hardwood that is not used in structural engineering nowadays. Analysis of known hardwood properties and its verification by experiment was made. Mathematic analysis using the PROMETHEE method was used for most suitable hardwood species selection in the Central Europe conditions. The most suitable hardwood – beech – was subjected for further tests: finger-joint load bearing capacity experiment and beech homogenous and hybrid glulam experiment. The test results are compared with the values from professional literature.
