Air tightness of building structures and critical details
Vávra, Petr ; Tichomirov,, Vladimír (referee) ; Bečkovský, David (advisor)
In thesis is dealt with problematic of how the value of air permeability may be affected by properties for water vapour diffusion with regard to OSB material There were chosen two main brands of OSB at Czech trade market Two specimens of OSB with different thickness were chosen for each brand. As a first the specimens were tested for air tightness to work out a value of air permeability for each specimen. Afterwords, the testing was conducted for gaining properties of water vapour diffusion on each specimen. As a final assessment was analysed the impact of properties of water vapour diffusion on the air tightness for each specimen. The general meaning of gaining higher air tightness with higher water vapour resistance was proved . It was shown that with raising thickness is usually gotten higher value of water vapour diffusion resistance. However it could not mean getting high air tightness. The crucial parameter is the quality of the material for gaining higher resistance against water vapour diffusion as well as for higher airtightness.

The roof structure of the sport hall in Mikulov
Sochorec, Michal ; Barnat, Jan (referee) ; Šmak, Milan (advisor)
Bachelor’s thesis describes design and static assessment of the roof structure of sport hall in Mikulov. Specifically the roofing of the two tennis courts and surrounding stands. Thesis examine several alternatives of design of roof structure like plate girders from glued laminated timber or truss girders made from solid wood. Girders span is 19 m above each tennis court. In the static calculation are assessed individual supporting elements and their connections. The thesis also includes fire resistant report of some elements of roof structure. Static analysis has been accomplished by student version of the SCIA Engineer 14 software.

Detached house, Sovinec
Pavela, Martin ; Žižka, Lukáš (referee) ; Bečkovský, David (advisor)
The aim of my bachelor´s thesis is design of dispositions and structural solution for family house in (municipality) Sovinec at the level of documentation for construction. The object is located on the northern slope. It is two-story detached building with basement. (Layout of basement garage exceeds from the first floor plan and because of this maximally exploit the possibilities of the building parcel). Structural system of the basement consist of stay-in-place formwork. The first and second floor is made of wooden frame construction. The basement is covered with intensive green roof. This roof is supported by prefabriceted reinforced concrete Spiroll panels. The rest of house has pitched roof and loadbearing part of this roof is in form of modern sliding collar. The object architecturally fits into the surrounding landscape and it is designed according to the plan of the municipality Jiříkov.

The roof structure of a multipurpose sport hall in Brno
Grussmann, Jan ; Pilgr,, Milan (referee) ; Šmak, Milan (advisor)
Bachelor´s thesis describes the design and static assessment of the main roof structure supporting elements of the multipurpose sport hall in Brno. It is the emphasis on the optimization of the proposal in terms of material consumption. Curved girders made of glued laminated timber and on the edge connected rafters forms together the cross-link structure. Basis of OSB sheathing carrying the roof deck is secured by the orthogonal grid system purlins and rafters. The static calculation also includes fire resistance reports of single elements.
