Weldability of steels for steam turbine parts
Jech, David ; Hutařová, Simona (referee) ; Juliš, Martin (advisor)
The aim of contemporary standard welding technologies is to create compact welds with high value of solidity and toughness in laboratorial and operational conditions. This welding technology is asserted in new creep - resisting steels on basis of steel CrMoV and CrMoNiV, which have high value of solidity and creep - resistance. The thesis deals with problems connected with the weldability of steels for steam turbine rotors and it´s aim is to interpret the structural and mechanical features of the weld joint for material combinations under consideration. For the assessment of weld joint features has been used measuring of micro hardness and hardness according to Vickers, microstructure was observed by methods of light microscopy.

New trends and material usage in bicycle frame design
Jelínek, Vladimír ; Němec, Karel (referee) ; Juliš, Martin (advisor)
Thesis in its first part summarizes the evolution of the bicycle from the draisine to the low wheels with a focus on the material of the frame of the bicycle. Also discussed in this section is an overview of small structural modifications, which were gradually used on a bike, like Bowden brake or the first type of transmission system. In the second part, the thesis describes the operating principles and types of suspension forks and disc brakes. Mentioned are materials that are currently used for bike frames with a focus on the advantages and disadvantages of each material used and its future anticipated use.

The Roofing of the Sport Hall
Müller, Radek ; Šmak, Milan (referee) ; Buchta, Stanislav (advisor)
In my project I dealt with a proposal pool roof in the town of Brno. As the main construction material was used glued laminated wood. For affiliate structure was used steel and solid wood. Construction has a span of approximately 40 meters, length 60 meters and a height about 11.5 meters. For a given type of structure and for aesthetic and ergonomic reasons, decided to design a curved beam of glued laminated timber supported by a pillar of glued laminated timber. End of the cantilever beam is supported by a steel column.

Multipurpose Sport Hall
Jakubíček, Tomáš ; Barnat, Jan (referee) ; Buchta, Stanislav (advisor)
I designed supporting structure of roofing for multipurpose sports hall located in Pardubice. Building height is 15 meters and the other two dimensions are 50x80 meters. It is an arched truss construction, which is located above the roof deck. The arch is asymmetrically supported with a height difference of supports 6.5 m. The actual frame is made out of steel S355 and is formed by circular profiles. The solution chosen offers free ceiling inside the hall and shows the supporting structures. Part of my bachelor thesis was to made static calculations and drawings.

Cowhouse in Králíky
Nováček, Tomáš ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
Bachelor thesis describes the structural design of the load bearing steel structure of cowhouse located in the municipality Králíky. The structure is designed according to the normative requirements of ČSN EN for ultimate and serviceability limit state. It´s a structure formed by the main frames at a distance of 5 m apart, which are placed in a rectangular plan of 30 x 60 m. As the main material of load bearing elements was used a steel S355. The specificity of the structure is location in a place with above average snow and wind loads. The couwhouse is intended for housing hundred and fifty cows. The work consists of a static calculation, which assessed individual cross sections and joints.

Reinforced concrete structure
Malecha, Tomáš ; Šimůnek, Petr (referee) ; Šulák, Pavel (advisor)
This bachelor‘s thesis includes structural analysis and check of reinforced concrete, cast-in-place construction of a building for parking. Here is solved locally supported floor slab above first above ground floor. Structural analysis was solved by program Scia Engineer 14 and checked by manual calculation. Next step was dimensioning for ultimate limit state, concretely for bending moment, punching and for serviceability limit state, concretely for limitation of cracks. For this bachelor’s thesis were made drawings based on calculated results.

Study of Precision of the Stability Analysis
Sotulář, Jiří ; Pilgr, Milan (referee) ; Hron, Lukáš (advisor)
The thesis deals with the precision of the stability analysis of the pressed member. The loss of stability of the bukling is determinate by using several metods, which are compared each other. The thesis is partitioned into three parts that works together. The first part deals with the theory of analysis of the buckling stability. Here is described the gradual solution of analytical analysis for real beam and here is described the final compared for ideal, imperfekt and real beam too. It is also short solved buckling by using software. In the second part is compared by using computing systems and anylitical analysis for several basic buckling systems. The results of the compared are summarised in the final graphs and tables for each solved element and systems. In the third part are designed and static checked load-bearing element of steel storage hall. The buckling beams are checked by using findings from the previous analysis.

Steel Structure of Multipurpose Hall
Vošček, Martin ; Buchta, Stanislav (referee) ; Hron, Lukáš (advisor)
Theme of this bachelor thesis is calculation and design of steel load bearing structure. The plan of the multipurpose hall is in rectangular shape with the width of 28m and length of 46m. The roof is in circular arch shape. Whole structure is designed from S355 steel. Structure is situated in Brno and is designed according the Eurocodes.
