Using Salome Meca computing environment to solve problems of solid mechanics
Ptáček, Tomáš ; Vaculka, Miroslav (referee) ; Vosynek, Petr (advisor)
Given bachelors thesis deals with solutions of basic tasks of body mechanics with usage of the finite element method (FEM). An open-source software Salome Meca with Code_Aster solver is used there. Basic formulas of strength of materials on which is FEM based are introduces in the beginning. Then is presented software Salome Meca with its solver Code_Aster. Followed by own solution of tasks, which contain structural analysis and series of examples for solving the fracture mechanics. Numerical solutions from Salome Meca are compared with analytical solutions, if some exist, and with solutions from commercial software Ansys Workbench.

Ceiling concrete slab in an industrial building
Revayová, Veronika ; Šulák, Pavel (referee) ; Strnad, Jiří (advisor)
The thesis is focused on the reinforced concrete slabs crosswise armed on a square plan. The supporting structure is made of reinforced concrete columns with massive bearers. It is a reinforced armoured concrete skeleton. The thesis solves various approaches to the computational models and their subsequent comparison. The hand-operated models with models with SCIA engineer 16.0 are compared in the work. The goal was to reinforce the slabs efficiently and determine the approximate variable load pressure that could be encountered during operation. Depending on the measured deflection, it is also important to find the reinforcement that might be present in these slabs. Other parts of the object are not concerned in this work.

REINFORCED CONCRETE TANK
Beran, Jakub ; Jeneš, Rostislav (referee) ; Šulák, Pavel (advisor)
The aim of the bachelor thesis is a static design of an reinforcement tank. The internal forces are calculated by FEM programme Scia Engineer 16.1 with a SOILIN modul interacting with a subsoil model. The internal forces are verified by a manual calculation. The load-bearing elements are designed with these forces. The structural assessment report is designed to ultimate limit state and service limite state – service limit state of crack. Another report considers ground water occurring. The static report deals with different time of concreting foundation slab and walls. This is the reason why shrinkage is very important for internal forces and their values. The objective of the project is to design the tank without cracks in concrete. The limit width of cracks is wk= 0,3 mm by EC 1992-1-1.

Structural assessment of the reinforced concrete chimney
Teplý, Jakub ; Hasala, Ivo (referee) ; Girgle, František (advisor)
The aim of this thesis is assessment of existing condition reinforced concrete factory chimney, who has undergone structural and technical survey, under which was found many failures caused of horizontally tension - significant vertical cracks in the chimney stack. The object of this work will also make appropriate proposals rehabilitation of concrete stack by design prestressed cables monostrand in horizontal direction, grouting open cracks and reprofiling surface of chimney stack.

Reconstruction of barn as a part of Miroslavské Knínice castle
Martínek, David ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
The bachelor thesis deals with the reconstruction of a barn in Miroslavské Knínice. First, it was necessary to examine the conditions of the barn. Crumbling masonry and cracks in perimeter walls had been found, so it was necessary to create a design and assess new solutions to repair the barn. On the basis of these defects, it was proposed to pull down a half of the barn, including the foundations and proposed to lay concrete over this part of formwork together with reinforcement.

Waterproof concrete structures and regulations for the design and implementation
Křenek, Daniel ; Brožovský, Jiří (referee) ; Hubáček, Adam (advisor)
This thesis covers the issues of design, production, and property testing in regards to waterlight concrete structures. The testing conducted on the properties fit in accordance to the Czech Republic and international regulations. This thesis covers the issues of design, production, and property testing in regards to waterlight concrete structures. The experimental part focused on the design of the concrete mix, which stems from previous knowledge of individual, and speific regulations. Various types of cement were particularly examined along with studying the effects of admixtures that were partially replaced by cement with propoerties of watertight concrete

Static provision of castle
Kulla, Lukáš ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
The aim of this final thesis was static protection for castle in Miroslavské Knínice. It was necessary to explore several respects and find signs of violation. Next analyze and propose suitable assurance of individual parts. Separe into the stages of construction and to consider the proposal in terms of ensuring the resistance of materials. Finally create a detailed documentation in the range suitable for performance. Based on engineering geology and visual survey was designed horizontal bracing prestressing cables at three levels. The first level "A" consists of a closed circuit of prestressed reinforced concrete passports, supplemented by the cross and construction of prestressed reinforced concrete passports. Next level "B,C" is used to secure the top of the building. Levels “B,C” are proposed using prestressed cable in spare cable channels.

Cast-in-place tank of sewage plant
Kustyánová, Orsolya ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
This thesis deals with the design and assessment of all supporting parts of a cast-in-place reinforced concrete tank of sewage plant in the village Vrbice. Tha main parts of the thesis are the technical report, static analysis, drawing documentations, construction process and visualisations. Calculation of internal forces was performed by the software Scia Engineer and verified by manual calculation. The drawing documentation constists of shape and reinforcement drawings of supporting parts.

Mixed construction of an office building
Fiala, Adam ; Zich, Miloš (referee) ; Perla, Jan (advisor)
Diploma thesis deals with analysis of a construction made of concrete and masonry. A model respecting nonlinear material behaviour of masonry was assembled in a finite element based software. Calculated results were used to analyse cracks in masonry. Next, a design of a horizontal construction was carried out - concrete slab with beams to support masonry in an upper floor.
