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.

Stress and deformation analysis of railway bridge over the Svratka River
Kovář, Jaroslav ; Žák, Stanislav (referee) ; Fuis, Vladimír (advisor)
This thesis deals with stress and strain analysis of real truss bridge structure. This structure is modelled as plane bar system. The opening part dedicates to theory, which is further used for calculations. The calculation part dedicates to compare statically determinate and indeterminate variation of structure for load by own weight and passage of the train. Analytic calculations are numerically verified with program ANSYS. In thesis is assessed concentration of stress, when the rivet drops out of the structure. The next part of thesis dedicates the spatial model of bridge, which is compared witch plane model.

Stress-strain analysis of the bar system
Pop, Miroslav ; Profant, Tomáš (referee) ; Houfek, Martin (advisor)
This bachelor’s thesis deals with the issue of rod systems, which represent a special type of construction widely used in the building and mechanical industry. In the introductory part is presented a theoretical basis and methods of static solution of rod systems are described, then it is described stress of rod systems and are derived relations that were subsequently used for the calculation of the specific example. In the practical part, the thesis deals with the analytical calculation of the planar rod system in shape of a power line pylon, for which the cross-sections of the members are designed and the magnitude of the stresses and deformation displacements are calculated. For the calculation, the general method of joints was used and cross sections were designed with respect to the elastic limit state and the buckling stability limit state. At the end of the work, the results of the analytical calculation were verified with numerical solution in software ANSYS Workbench.

The Structure of the Atypical Family House in Vrchlabí
Vondráček, Vít ; Hron, Lukáš (referee) ; Šmak, Milan (advisor)
The subject of master’s thesis is design and assessment of steel load-bearing construction of atypical family house in Vrchlabí. Structure is designed as multi-storey steel structure, cooperating with stiff concrete core. The design was considered in four different options which combines possibility of using steel, steel and timber with different way of stiffness for whole structure. There is also composite steel-concrete alternative floor trimmer for selected option. Design and assessment was conducted in accordance with the applicable standards and by using software Scia Engineer.

Analytical Design Optimization of a Structure
Šubíková, Magdaléna ; Vlk, Zbyněk (referee) ; Hokeš, Filip (advisor)
The bachelor thesis deals with an analytical optimization of the construction design. Designed structure was inspired by a steel structure of the Bernard lookout tower. The analytical optimization was performed on a partial model of the structure and static analysis was obtained using the direct stiffness method. Two models for optimization were created in Scie Engineer 20.0 – one partial, the other complete. The impact of the optimization on the mass and cost of the structure was assessed.

Exhibition Pavilion
Shánělová, Lenka ; Šmak, Milan (referee) ; Bajer, Miroslav (advisor)
The Master´s thesis contains design of steel construction of exhibition pavilion, which is consists of columns, dome, lantern and suspension footbridge. Building will be intended for organizing exhibitions and conferences by town Trutnov. Two models of variants of dome´s construction are drafted in this work– Schwedler´s and Föpple´s dome. Models are space tubular structures.The work contains static assessment of spatial structures and spherical steel joint in program SCIA Engineer for both variants. Hand assessment of bars, basic details and anchoring, technical report and drawing dokumentation are drafted for selected variant construction with Schwedler´s dome.

Napjatostně deformační analýza mostu ve Starém Městě u Frýdku-Místku
Janík, Rostislav ; Profant, Tomáš (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis analyses stress and strain of real railway bridge. Construction of bridge is modelled as plane bar system. The fisrt part of the thesis deals with a research, which includes obtaining information from theory, which is necessary for the right solution of the task. Next part dedicates to analytic solution of statically determinate and indeterminate variation of structure for load by own weight and also for load during passage of the train. In the next part are the results of analytic solution verified by numerical solution in program ANSYS. In the last part is evaluated the risk of buckling for all variations of the load.
