Office building with production hall
Břečka, Jan ; Balázs, Ivan (referee) ; Horáček, Martin (advisor)
The aim of this diploma´s thesis is to design steel-concrete structure of the office building and steel structure of production hall situated in Moravské Budějovice. The dimensions of the office building are 48,0 x 60,0 meters and height is 17,0 meters. The main constructional material is S 255 steel and C30/37 concrete. The load bearing structure of the hall consists of the columns, primary and secondary beams. The axial distance of columns is 6 meters (5 meters). The dimensions of the production hall are 24,0 x 60,0 meters and height is 12,0 meters. Inside the production hall is craneway. An analysis of two solutions of the supporting structure was performed. The first variant is consists of rigid frames. Truss girder in the second variant is an alternative solution. Both variants were compared and the amount of steel was found. The selected option was developed in greater details with static calculation, drawings and material report. The static analysis of the main load bearing parts of the structure is processed. The calcuation were made in accordance with the European design codes.

Replacement of headlamp parts screw fixation by a plastic nail
Lysa, Bohuslav ; Píška, Miroslav (referee) ; Polzer, Aleš (advisor)
The master thesis covers several issues linked to a substitution of headlamp screw fixation by a plastic nail. The thesis includes an analysis of the headlamp technology, including description of the prescribed durability tests. On the basis of the analysis some new designs of plastic nails are proposed, consistent with characteristics of plastic materials. Selected outcomes of the analysis have been tested as prototypes and verified with Finite Elements Method in SimDesigner including 3D modeling capabilities provided by the Catia V5. The feasibility study regarding a casting form of the new design of plastic nails and technical economic valuation for contingent assembly mounting is included in the thesis.

Comparision of FEM models of joints
Hlaváč, Martin ; Hrůza, Václav (referee) ; Pokorný, Přemysl (advisor)
This thesis deals with the comparison of alternative models of the simplified joints used in the FEM models of complex models with detailed joint details. This is essentially a screw connection with dowel bolt and standard bolt, weld connection "T" and overlap weld connection. Individual connections are compared in the simulation results of matching models.

On the fixing and anchoring technology
Klein, Adam ; Kouřil, Karel (referee) ; Píška, Miroslav (advisor)
Bachelor thesis is focused on practical analysis of used anchor elements for particular areas. The beginning of the thesis devides anchor and fastening elements based on its construction as well as information meant for correct element proposal, especially in civil engineering. The thesis also mentiones couple of examples where anchoring makes the most important part for the overall functionality. Second part of the bachelor thesis focuses on materials and element’s surface adjustment, espacially against corrosion. In conclusion, there are mentioned examples of testings, whether for the particular element’s resistance to corrosion or for its cohesiveness in anchored bedrock.

Design of facility for egg-shells transportation
Hruška, Kryštof ; Naď, Martin (referee) ; Pernica, Marek (advisor)
Egg shells are a very suitable basic raw material for the production of mineral dietary supplements. The thesis deals with one of the processes in their production, the transportation of the commodity after flush into a clean room. The thesis proposes possible solutions, which are described in the research part, on the basis of which a screw conveyor is chosen as a suitable solution and a design solution is proposed. Based on the calculations, the individual parts of the conveyor are selected and designed. The entire device is modeled in SolidWorks and the drawing documentation contains the overall drawing of the assembly.

Roofing of the winter stadium
Kašpír, Filip ; Pešek, Ondřej (referee) ; Horáček, Martin (advisor)
The subject of this bachelor thesis is the design and assessment of a steel roof structure of the winter stadium in the city of Olomouc. The new layout solution takes into account the current dimensions of the stadium. Ground plan dimensions of the structure are 101x73 m with the maximum height of 30.5 m. The main load-bearing part of the roof structure is represented by a truss, which has the shape of an arch. The arch is latticed. With an axial distance of the upper and the lower belt of 3.0 m and axial distance of the trusses of 5.0 m. Spatial rigidity is ensured in the transverse and longitudinal directions by stiffeners, which are distributed symmetrically. The bachelor thesis contains a static calculation of purlins, truss, gable wall and of joints. The whole roof structure is then clad with panels.

Production of the screw
Starý, Petr ; Podaný, Kamil (referee) ; Císařová, Michaela (advisor)
The bachelor´s degree project deals with the production of rotating component using cold forming technology. There are described basic principles of technology, used material, tools and machines and the area of usage. Production of the screw is based on the literary studies and technical calculations. The suggested manufacturing variant consists of five steps and containing cutting, extrusion and upsetting. As raw material was chosen a wire with diameter of 12,5 mm and length of 38,6 mm made of steel 12040. For chosen variant was made technological and strength calculations for the individual operations.

Roofing of the summer house
Maxová, Natálie ; Bukovská, Pavla (referee) ; Barnat, Jan (advisor)
The subject of the bachelor´s thesis is to design and assessment of the load-boarding roof structure of a holiday house in the village of Nové Hrady, district of České Budějovice. It is about saddle roof with a slope of 20° above one-story building rectangular floor plan about dimensions of 7,5 m x 20,6 m. The structural system of the roof is made of a pair of wooden rafters made of grown wood, conected by a steel rod to a steel vertical. The peripheral load-bearing part under the roof structure are sand-lime walls and frontal wooden columns in the glass wall. The structural model was modelled in Dlubal RFEM 6.02. The software was used to determine the internal forces and judgments on the individual elements. The decisive judgments were verifies by manual calculation. Selected bolt or screw connections and the connection of the slab to the rafters were also resolved.
