Additional reinforcement of wood elements
Janoušek, Radek ; Vejpustek,, Zdeněk (referee) ; Vaněrek, Jan (advisor)
This diploma thesis deals with the possibilities of additional reinforcement of wooden elements using different types of BFRP materials. In the practical part, an experiment of reinforcing plywood with external reinforcement using BFRP fabrics with different basis weights was performed. As part of the strength tests performed, the specimens were subjected to bending and shear stresses. To verify the bonding quality of the plywood, the bodies were exposed to the effect of elevated temperature and a delamination test was performed to determine the bonding quality of the plywood joints. The achieved values were evaluated and compared with the available literature.

Experimental Measurement of Dynamic Changes in the Basis Weight of Vegetation Walls and Facades Due to Evapotranspiration
Vystrčil, Jan ; Nespěšný, Ondřej ; Cakl, Dominik
Green wall and facade systems are a modern element of building construction. To ensure the correct design and functionality of these systems during their life cycle, it is necessary to describe their properties. One of the basic properties of facade and cladding elements is the basis weight. It depends on the chosen system of vegetation wall or facade, the chosen amount, and species representation of vegetation and, last but not least on the surrounding conditions of the installation site. Given that these are living elements, it must be stated that this property cannot be expressed in a single value, but in a mass range. Due to the great difference between these systems and standard cladding or façade elements, standard testing methods are not applicable for determining the basis weight. This paper describes a possible methodology for determining the basis weight of vegetation facade systems and their changes over time.
