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.

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.

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 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.

Posouzení využitelnosti vybraných listnatých dřev pro výrobu kompozitu na bázi dřeva
Kašpařík, Matěj
The bachelor thesis deals with the issue of the possibility of replacing spruce wood in the production of OSB with hornbeam and birch wood. The purpose of the thesis is to compare selected physical and mechanical properties of OSB made of these woods with standardized properties of OSB. In the first part, the origin, characteristics and current use of OSB are presented. The second part deals with the material and methodology of all the tests performed. The following properties of the boards were investigated: moisture content, flexural strength and elastic limit, density profile, swelling, delamination and shear strength of the glued joint. In the third part of the paper, the results of the tests and their comparison with the standard requirements for OSB are presented, followed by a summary and discussion.

Posouzení využitelnosti vybraných listnatých dřev pro výrobu kompozitu na bázi dřeva
Mišičák, Patrik
The bachelor thesis deals with the assessment of the usability of alder and aspen wood for the production of wood-based composite, specifically the production of OSB. It uses the experimental analysis carried out to evaluate the applicability for sheating materials of timber frame structures. First section reviews particleboard with a focus on OSB. It summarises the importance, use and production of OSB panels and focuses on alternative raw material types for the production of wood-based composites. Describes the various technological processes involved in the production of OSB. The second part focuses on the individual production operations and shows the measurement procedures carried out. It also illustrates the determined data and the statistical methods applied to them. Based on the statistically processed data of selected physical and mechanical properties of the manufactured boards, it compares and evaluates the determined values with the requirements specified in standard ČSN EN 300, corresponding to the given application.

Energetické parametry při formátování aglomerovaných materiálů
Pitrman, Dobroslav
This bachelor's thesis is devoted to energy parameters while formatting agglomerated materials (MDF, Particleboard, OSB). This is primarily the effect of chip thickness on the cutting and sliding force size when cutting individual materials. During the experiment, different saw blades with different body modifications were used. The collected data were compared with the measured data and the calculated value of the average chip thickness. The dependence of the size of the cutting and sliding force on the mean chip thickness was demonstrated. As the thickness of the chip increased, so did the values of the individual forces. The effect of the machined material on the cutting force was quite significant. The internal structure of individual materials mainly influenced the cutting force. The smallest cutting force was measured with MDF and the largest with OSB. The influence of adjustment of the saw blade did not have such a significant effect on the size of the cutting force as the type of material being cut. Comparing all of the discs that had been used, the lowest cutting force measured was, on average, done by the discs with copper rivets. It was also statistically proven to be dependent on the size of the cutting force.

Posouzení vybraných vlastností konstrukčních materiálů pro dřevostavby
Schiel, Jakub
At first this diploma thesis tests and compared selected physical and mechanical properties of various construction materials. Furthermore, thesis compares results with measured values determined by manufacturer. In next part of thesis is de-signed similar wall composition which is differs only by sheeting material. On every wall composition was calculated heat transmittance. Compositions are compared with each other, further there are compared economically.

Beuron Art in the Emmaus Monastery
Čermáková, Veronika ; Foltýn, Dušan (advisor) ; Jarošová, Markéta (referee)
The bachalor's thesis "Beuron Art in the Emmaus Monastery" examines an unique phase in the history of Emmaus Monastery influenced by Beuron Art. It presents to reader a preview of the artistic transformation of the monastery from 1880 until it's critical destruction on February 14, 1945, when became to unwanted object of the bombing of Prague. We can find out about the monastery restoration process realized in the following years. Another part of the bachelor's thesis gives us general information about Beuron Art School and it's main representatives. Then it shows the significance of this artisitic style and maps it's other artworks in Prague. Keywords Beuron, Beuron Congregation, Beuron Art School, Emmaus Monastery, OSB, sacral interior
