Optimized design of reinforcement of concrete cross section
Hudyma, Nazar ; Laníková, Ivana (referee) ; Štěpánek, Petr (advisor)
The subject of this thesis is the optimization of design variables of reinforced concrete cross-section, especially its reinforcement. To solve this problem, it was first necessary to elaborate a search section that discusses various methods and approaches for solving the problem. The research part also includes processing and evaluation of tasks solved by other authors in available literature. For the optimization task, in the following parts both the general formulation and the detailed formulation of the partial parts of the concrete reinforcement structure optimization process are processed. As an example of optimization, a simple beam is chosen, which is subjected to bending moment and normal force one load case, where the example will be divided according to the formulation of both the function and the vector of unknown parameters (variables) defining the exact shape and properties of the reinforced concrete section. The examples will then be tested with regard to the speed of convergence and the degree of deviation between the best solutions found for each optimization algorithm used. At the end there will be a comparison and evaluation of the solution of the given task, as well as a summary of the whole bachelor thesis with reference to another possible direction in the optimization problems focused on reinforced concrete structures. In the appendices there will be a solution of selected examples.

Design Of I/34 And II/164 Crossroad Near Jindřichův Hradec
Kokeš, Ondřej ; Krčmová, Iva (referee) ; Radimský, Michal (advisor)
This is an adaptation of the existing intersection, which their arrangement is unsatisfactory and there is becoming a serious accident. This work proposed three options. In the first variant is proposed the roundabout. The proposal is located in the existing conditions, to prevent expansion of plots. In the second variant is designed turbo roundabout with spiral arrangement of lanes. This proposal also uses space in the existing condition. In the main direction of the traffic intensity is designed bypass. The third variant is designed as joining intersection, which is also located in the existing conditions. The focus of the third option is to change the main traffic routes and design of the connecting and cornering lane.

Analysis of roofing structure of production hall
Jedelský, Martin ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis deals with a static analysis of a production hall roofing and suggests possible alternative solutions. The model has been created based on project documentation received and valid regulation ČSN EN in software Dlubal RFEM 5.06. The goal of the bachelor thesis is to analyse and create a model based on project documentation and suggest alternative options in order to increase the utilization of space, feasibility and to potentially lower the costs.

Static analysis of acoustic enclosure
Hándlová, Barbora ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The subject of this Bachelor’s thesis is a structural analysis of acoustic enclosure, which is located above production facilities. The enclosure is assembled of elements with a load-bearing skeleton made of steel. It is possible to dismount the enclosure in parts. Computational software RFEM was chosen to model the 3D structure. The aim of this thesis is an assessment of ultimate and serviceability limit state of some selected elements. Some of the results obtained from the RFEM program are verified by hand-done calculation.

Study of throught road in the village of Nosislav
Mrštinová, Romana ; Coufalíková, Iva (referee) ; Kosňovský, Michal (advisor)
The main aim of my bachelor thesis is calming of road II/425 in the village Nosislav. Communication will be adjusted width and direction, the proposal of areas for parking, establishment of bus bays, connecting local roads and entrances to buildings and secure of movement of cyclists and pedestrians will be part of the solution. Crosswalks with protective islands will be also designed newly. The study use roundabouts as a soothing elements before entering the village while ensuring the safe operation of the crossroad. To create documentation computational systems will be used. The proposal will comply with the relevant standards and regulations.

Determination of nuclear reactions' microscopic cross-sections using an accelerator-driven neutron source
Filová, Vendula ; Šťastný, Ondřej (referee) ; Král, Dušan (advisor)
Tato práce se věnuje určení mikroskopických účinných průřezů interakcí neutronů s indiem. Teoretická část shrnuje neutronové zdroje používané ve vědě i průmyslu, popisuje princip jejich fungování a představuje příklady jejich aplikací. Praktická část obsahuje postup vyhodnocování velikostí účinných průřezů včetně jednotlivých provedených korekcí. Byly vyhodnocována data celkem ze tří experimentů, při kterých byly produkovány neutrony interakcí protonů s tenkým lithiovým terčem. Kvazi monoenergetickým neutronům byly vystaveny sendviče folií včetně foile z india, produkty interakcí byly měřeny pomocí gamma spektrometrie. Výsledné mikroskopické účinné průřezy jsou porovnány s daty z knihoven evaluovaných dat a z knihovny EXFOR.

Static analysis of sports hall
Jedlička, Michal ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
This Bachelor´s thesis is about the static analysis of sports hall in Libina. I have used a program RFEM for making the model. The model was elaborated according to the provided project documentation and valid regulations ČSN EN. The aim of this work is to analyze the real construction and to point out to the formation of possible problems.

Planetarium
Sokolová, Eva ; Šmak, Milan (referee) ; Barnat, Jan (advisor)
The master’s thesis object is to create a design of a load carrying steel structure planetarium. Its ground plan dimensions are 36,1 x 49,0 m. The planetarium hall’s roof is designed with system of trusses and purlins. The projection hall’s roof consists of ribbed cupola with radially arched ribs. The stiffness of the whole construction is ensured with bracings. The walls of the whole object are composed of columns, rails and bracings.
