Stress-strain analysis of the railway bridge in Zahrádky near Česká Lípa
Abdul moghni, Abdul rahman ; Vosynek, Petr (referee) ; Fuis, Vladimír (advisor)
Cílem této bakalářské práce je využití deformačně napěťové analýzy na Železniční most v Zahrádkách u České Lípy. Konstrukce mostu byla zjednodušena a vymodelována jako nosníková konstrukce. První část bakalářské práce byla věnována získávání vstupních dat a základních informacích z technické dokumentace mostu. V nosníkovém modelu bylo využito několik zjednodušení. První model považujeme za staticky neurčitý, zatímco druhý jako staticky určitou konstrukci. Každý model tedy obsahuje zátěž z důvodu vlastní váhy a zatížení způsobeno projíždějícím vlakem. Z důvodu objemnosti rovnic, využíváme k výpočtu software Maple. Zkontrolovali jsme i mezní stav vzpěru pro oba modely, avšak jsme uvažovali pouze zatížení vlastní váhou a zatížení způsobeno vlakem. Po získání analytických dat bylo důležité tyto výsledky ověřit. Toto bylo docíleno využitím metody konečných prvku za pomocí programu Ansys. Veškeré výpočty byly provedeny pro 2D modely. Jediná výjimka je numerická sekce, kde byl přidán 3D model za účelem porovnání s 2D modelem.

Lanthanocene Catalysts for Synthesis of Polymers Applicable in Medicine
Slanina, Ondřej ; Kábelová, Božena (referee) ; Richtera, Lukáš (advisor)
The theoretic part of the thesis focuses on materials used in medicine. The metallic, ceramic, glass-ceramic and polymer materials are systematically described. The biocompatibility of the materials and possible threads of their usage for manufacturing of medicinal devices and implants are emphasized in the discussion. The work is focused especially on polymer materials. Different types of polymerizations are summarized with the accent on the preparation of biodegradable materials. In the practical part the synthesis of two organometallic bis(pentamethylcyclopentadienyl) sandwich complexes with holmium and gadolinium as a central atom designed for preparation of materials suitable for biomedicine is proposed.

Aviation maintenace crane
Bureš, Martin ; Šťastný, Antonín (referee) ; Pokorný, Přemysl (advisor)
This master´s thesis solves design of a mobile crane for handling air aggregates and ejection seats. Handling crane provides lifting a maximum weight of 300 kg to a height of 4600 mm. Subject of the work is the choice of appropriate technical solutions, design of lifting mechanisms, supporting structures and accessories. The suitability of the solution is checked by strength analysis of individual units. Another task is to provide mobility equipment and control stability against overturning. The appendix includes protocols static analysis of the program Nexis32, drawing overall crane assembly and manufacturing drawings selected parts.

Revitalization Program of Floral Garden in Kromeriz
Doležel, Martin ; Sochor, Jan (referee) ; Ponešová, Barbora (advisor)
THE GARDEN IN A CRISIS The first problem. Moving the entrance from the rotunda axis in the north to the area where the farmyard surrounded by greenhouses is situated. The consequence of this step was destruction of the conception of a floral garden and further, confusion of a visitor caused by the new and excentric garden entrance. The second problem. The original noble fill of the forefield has been perfectly cleaned, including the structure. Therefore the courtyard of honour is wedged in the two huge unspecific areas. The third problem. The nineteenth century is gone. Nowadays visitor is hard to please and unconcentrated. THE CONCEPTION Revitalisation and amendment of the forefield structure concept in subareas is both practical and it offers the esthetic quality which was lost. In relation to the axis of the garden, the area is adversely divided by some new buildings. These functional stripes make the optical barriers and they are clear in their axis. There are minimaly two six smaller areas created out of two bigger ones. Moving the main entrance from the courtyard to the rotunda center line means a possibility for the garden to step out towards its future development without some drastic changes in a objects which are part of a monument conservation but not functionally defined any more. The more, the garden gets its lost axiality, sense and a story about men's journey again. The application of the principles of the baroque garden in filling of the forefield gardens is either wrong or not considered properly. Polarized (and polar) gardens offer extreme positions of two contradictory trends. A superframed garden made by the nowadays technology versus a grove of wisdom where the nature is both a constructor and an architect. All of this with a baroque garden somewhere in its centre.

Annes, Extension and Building Adjustment of the Building House Neumannova in Brno, Preparation and Realization of Buildings
Martincová, Michaela ; Patloka, Jiří (referee) ; Šlanhof, Jiří (advisor)
The thesis deals with the technological stage of the rough construction of the annex and the reconstruction of the apartment building on Neumannova Street in Brno-Pisárky. These are earthworks, rough substructure, rough construction, demolition work, and some of the finishing work. The diploma thesis deals with the design of the work process of the works, the design of the machine assemblies, the studies of the implementation of the main technological stages, the preparation of the budget item, the time schedule, the time and the financial plan of the object, the control and testing plan, the material assurance plan and the transport relations. Further, the design of the building facility is processed and a technical report of the building facility is made.

The roofing of a railway station
Olbert, Jan ; Šmak, Milan (referee) ; Puchner, Josef (advisor)
The goal of this thesis is structural design of railway station lobby steel roofing. The construction dimensions are 63,0 m x 300,0 m with height adapted for railway vehicles traffic according to ČSN 73 6320 technical standard. The two-bay hall cross coupling consists of lattice trusses mounted on restrained columns. Axial spacing between individual bonds is 4,0 m. In the longitudinal direction the stability of articulated columns is secured by truss bracing placed in the roof and walls.

Timber structure of a multipurpose garden house
Hoffmannová, Zdislava ; Barnat, Jan (referee) ; Šmak, Milan (advisor)
The subject of this bachelor’s thesis is a design of a timber structure of a multipurpose garden house. The ground floor of the house serves as a garage, the attic serves as a playroom for children. The building is located in Letohrad in Pardubice Region. Structural system is a timber framed structure which has been created as a spatial bar model in CADKON+ 2017 software. The internal forces have been calculated in SCIA Engineer 18.1 software using the linear static analysis. These forces have been used to design structural elements. Final results have been partially verified by hand calculations. Solid timber of C24 quality has been chosen as a proper material.

Sports hall
Hellebrand, David ; Puchner, Josef (referee) ; Sýkora, Karel (advisor)
This bachelor’s thesis deals with a project of roof load-bearing structure of a sports hall situated nearby the city of Opava. The sports hall would be designed for common sports such as handball, football, tenis, voleyball or basketbal. Groun plan scantlings of the con-struction are of 36 x 48 m and clearance of 8 m. Hall travers bond is composed of 3 m high lattice frames that are hinge-connected to a housed joint. Accouplement between the sup-porting lattice frames is done due to longitudial effective purline which continue to the wall-mounted parts of the structure. Spatial rigidity is made safe due to sway bracings and purline.
