Static analysis of the cylindrical tank
Frimlová, Eva ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis describes structural analysis of cylindrical tank. The goal of this thesis is creating a computational algorithm in a software called MATLAB, using which the structural analysis on idealized models of cylindrical tank is solved. These models are the rod model and the model with plane elements. This bachelor thesis is divided in several parts. Firstly, there is defined the structure, material and load of cylyndrical tank. Second part is about rod model, stiffness method and the calculation using this method. Next part is about model with plane elements, finite element method and its calculation. In the last part, there are results from each part and their comparison.

Certified method for evaluation of biological efficacy of controlled atmospheres and fumigation in silos using biotest kits: methodology for workers in DDD, agriculture and food industry
Aulický, Radek ; Stejskal, Václav ; Plachý, Jan
Evaluation of the efficacy of controlled atmosphere or insecticide fumigation treatment of stored commodities is very difficult when these materials are located in silo bins. The main difficulty is to take measurements and samples within the entire commodity (vertical-silo) profile. Until now, there are no standard procedures and tools that would allow the evaluation of efficacy of controlled atmospheres under such situations. These methodical deficiencies are some of the main reasons why t controlled atmosphere methods are not commonly used in practice, although they are – under many conditions - relatively cost-effective disinfection measures. This methodology is the first Czech set of procedures for the proper preparation, application and evaluation of bioassays that can be used for evaluation of the efficacy of controlled atmospheres and fumigation in silo bins cells. The methodology also shows some practical examples and experimental results on how to use bioassay. The certified methodology was prepared with the financial support of the NAZV agency and is the technological an scientific output of the project QJ1310057.

Project of silo for powdery materials
Vydra, Jan ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis is solving systems design of silo for powdery materials. There is analysis of type choise and silo construction, dimension design and silo strenght calculation. There are described the possibility of emptying the vaults and ways to suppress the possible emergence of the vault using aktive and passive elements, that condustive to flow. It also describes active and passive stress state of the material in the silo. There are evaluated various options for editing the silo for different materials.

Project of grain silo
Pilař, Vlastimil ; Malach, František (referee) ; Malášek, Jiří (advisor)
The goal of the Master thesis is to design a grain container. The thesis involves a possible method of grain storage depending on the quality and condition of the grain and also the ways of filling and emptying the container with all the problems that might occur. The thesis deals for example with a possibility of occurrence of vault and with it associated change of state of stress, or with the pressure surges in the container. The thesis involves an analysis of an appropriate construction solution, a design of the main dimensions of the container and a test calculation of the container ´s strength.

Sugar storage tank
Kotík, Libor ; Musil, Jiří (referee) ; Zich, Miloš (advisor)
The matter of this thesis is static design and examination of prestressed storage tank to 50000 tons of sugar. Computational model of the steel roof structure is processed and its effect on the silos. Loads is provided of sugar. Optimal design is performed and assessment ultimate and serviceability limit state reinforced concrete and prestressing horizontal silo wall including local load. Next, it is performed the design of a reinforced concrete of the plane bed and column and assessment at the ultimate limit state. The thesis is also drawing documentation, technical report and visualization of construction process. The aim of this work is to the design of the main components based on the required storage capacity tank, mechanical properties of the stored material and technical amenities.
