Proposal of a program for solving of problems of simple tension/compression of bars and strut frames
Martínek, Tomáš ; Kubík, Petr (referee) ; Polzer, Stanislav (advisor)
The aim of this work is a program that will solve problems from the simple tension /compression bars and strut frames in the range of bachelor. The work consists of two programs developed in the Borland Delphi development environment. The programs allow the user to define a bar (strut frames) on the basis of the geometrical parameters and constraints, determine the rate of statical indetermination, make the necessary calculations and, if necessary, indicate the condition of deformation (a program for solving bars). The written part of the work serves as a manual.

ResPublica/Civitas Socialis - Strachotín
Ildža, Lukáš ; Klein, Pavel (referee) ; Nový, Vítězslav (advisor)
The aim of the project is to design a public building in the place, where phenomena of Pálava mountains, reflecting water surface and wine tradition meet. It is right in the area of Strachotín village. Project is trying to harness the power of these qualities to create a special attractive house. But also, the house is showing the viewer new perspective on these entities, which would not be seen without it. The location and concept of this wine house is strengthening the link between village and Pálava reflected in water. Therefore, the main part of interior is oriented exactly on the axis between these two poles. Secondarily, house contains the small museum of local history. In terms of technical aspects, we are dealing with the floating house, which is not affecting the building of dyke in no way.

Multipurpose facility Olomouc
Ocelík, Tomáš ; Klvaňa, Jiří (referee) ; Eliáš, Luboš (advisor)
This thesis is focused on designing a new multipurpose building with parts used for apartments, administration offices and a bar. The land, which the building is situated on, is located in the city of Olomouc. The structure consist of five above-ground floors and one underground floor, where a garage is designed. The vertical supporting construction are made of reinforced cast-in-place concrete columns, the horizontal of reinforced concrete cast-in-place boards, other vertical walls are made of sand-lime and aerated concrete blocks. The roof is warm flat.

Static analysis of steel footbridge
Mareková, Adela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The subject of the bachelor thesis is static analysis of a steel footbridge. Two different models of this structure are created in RFEM 5.16 software. The first model consists only of the upper part of the structure, the second model includes also the bottom part – columns. The load is calculated manually and applied on both models in the same way. RFEM software was also used for performing the calculation. The results from models are compared between each other and ultimate limit state assessment is carried out.

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 crane truss loaded by a force with varying position
Cabaj, Gabriel ; Fuis, Vladimír (referee) ; Vaverka, Jiří (advisor)
The bachelor thesis deals with the stress-strain analysis of the truss of a gantry crane. The theoretical part clarifies the basic concepts of statics, elasticity and strength. The concept of influence lines and its use for solving stress-strain analyses of structures with variable position of the loading force is further presented. The practical part deals with a model 2D example, specifically, the design of a cross section for a simplified model of a gantry crane, which is represented by the truss structure. The results for trusses with different degrees of static indeterminacy are compared. Subsequently, the analytical results are verified by the numerical solution in ANSYS software. In the last analysis, a 3D model of a gantry crane with realistic parameters from available sources is created. Finally, the stress-strain analysis of the gantry crane is performed considering the variable position of the loading force.

Stress-strain analysis of stadium lighting mast
Tokoš, Richard ; Kovář, Jaroslav (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis contains an analysis of a steel structure that serves as lighting in a football stadium. The main goal is to create a bar system, the equation of static equilibrium and the deformation condition and I will analytically solve the stress and strain. Then I will create a model in ANSYS and calculate the stress and strain numerically. The bachelor thesis contains a comparison of the results of these methods.

Hotel in Bojnice
Hoang, Dong Thy ; Semrád, Antonín (referee) ; Štěpánek, Ladislav (advisor)
This diploma´s thesis deals with the processing of project documenation for a four – storey, none – basement, hotel building with a restaurant in Bojnice. The restaurant and a bar is accessible from the first floor, with seperate entrances. Additionally, there are twenty-six aparments on the second and third floor, where two of the apartments are barrier-free. Technical rooms, and offices rooms are designed into the last floor.

Calculation of heat and force field UniGear ZS1
Mokrý, Lukáš ; ABB, Drahomír Tůma, (referee) ; Dohnal, Petr (advisor)
The aim of my work is to describe high-voltage switchgear type UniGear 500R, which is part of UniGear switchgears family. I will focus on heating issue of one 500R unit and its parts during operation. Maximum values of this heating is limited by standards and can´t be exceed to ensure safe and reliable operation. That is why the heating tests are necessary part of designing and developing switchgears. Calculation will be made by two different ways. First is classic one-pole heating net method and second is numerical simulation in Solidworks flow simulation program. Except the theoretical description there will be presented also used 3D model and explanation of both method, used to calculation and simulation. Last point of this work is measuring of this type of switchgear and getting real data. The main point there is to compare measured values with values calculated and decide if is possible to simulate tests with appropriate accuracy. Then would be also possible to substitute the real test in laboratory, which costs many thousand crowns and takes lots hours of time. This work is collaborated with EJF division of ABB Company, where I am employed. Heating issues in this company is always on process, because of developing and improving of their products. So this work could be helpful in this field. ABB provides all materials needed, especially technical catalogues, 3D model and final values from laboratory measuring. Support from college faculty is mainly in study consultations and proposing of calculations making. In the end of work will be make final comparison and evaluation of achieved results.
