Design of reinforced tank
Štramberský, Martin ; Sliwka, Pavel (referee) ; Zich, Miloš (advisor)
The matter of this diploma thesis is a static storage tank for petroleum substances, the study of a solution for appropriate shape of shell and its effort to dihedral for roofing, and the study of effect of the storage of inner roofs walls of the tank to the size of the internal forces. The internal walls are carried out by the method of finite elements in the engineering program Scia Engineering 2013 and on the basis of it, designing of the framing sections of the tank. There is a calculation part of the lower horizontal bias wreaths of the shell and internal supporting wall. All the components are assessed on the 1st limit state of the load-bearing capacity and the 2nd limit state of the application (emergence cracks, limiting voltage in the concrete and a prestressing steel). The existing external wall is assessed only on the marginal status load of carrying capacity. The part of diploma thesis is also drawing documentation, accompanying report and technical report. The goal of the diploma thesis was to design the tank without an occurrence of the cracks in the concrete so as the vertical wall was prestressing only in the horizontal direction and the optimal proposal roof tanks as an addition.

The concrete structure of a high office building
Skuhravý, František ; Pulec, Vladimír (referee) ; Perla, Jan (advisor)
Aim of The Diploma Thesis was to design load-bearing structure of a multi-storey reinforced concrete building, to realize structural analysis in Dlubal-RFEM software and dimension its selected parts. Designed structure is based on already erected building in office edifices campus in Brno-Slatina district. Its original number of storeys was increased from ten to nineteen, so the specific problems connected to high-rise building designing could be solved. Time dependent deformations of vertical structures were analysed in detail, so the changes in load of horizontal elements could be described more precisely, because of its direct dependence on compression of the columns. Within the paper, foundation structure dimensions were designed, assessment and design of composite columns assembly were made, as well of floor slab in 2nd floor with column deformations impact check on the 17th floor. Also, the external walls, pillars and shear core walls were designed and assessed. Formwork drawing of designed structure parts and detailed drawing of reinforcement of assessed elements were elaborated. Based on Diploma Thesis results it can be stated, that if influence of nonuniform load of vertical structures within the high-rise building designing is neglected, consequent project would presumably be uneconomic, or dangerous after an optimization attempts.

Retaining Walls
Michalčák, Jan ; Fiala, Radek (referee) ; Glisníková, Věra (advisor)
This bachelor thesis deals with retaining walls, methods of the design and defects. The thesis then focuses on gebion retaning walls and their defects. The adopted design of the model of gabion for the calculation through final element method (FEM) is here processed and verified. In the practical part findings are applied to a real situation along a cycle path near the village called Tatranská Polianka. The designed retaining wall from gabion baskets is calculated analytically, using the programme GEO5 and PLAXIS 2D. In conclusion, results are evaluated and compared.

Napjatostně deformační analýza mostu v Třineckých železárnách
Ščerba, Bořek ; Skalka, Petr (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis analyses stress and deformation of the truss construction. The first point of the thesis is a research, which includes obtaining information about the construction, for exemple dimensions, loads, purpose, history etc. Then, calculation models are created considering a different level of simplification. Two analytical models are crutial for the thesis – one statically determinate and the other statically indeterminate. They are used for analysing two different loads applied to the construction using methods of solid mechanics – it’s own weight and its own weight in combination with a weight of a vehicle that is driving through. Afterwards, the statically inderteminate model is verified using finite element method (FEM).

Multi-span bridge structure
Necid, Miloš ; Brtáň, Stanislav (referee) ; Koláček, Jan (advisor)
I deal with the road bridge near Velké Meziříčí in the thesis. The highway bridge overcomes valley 360 m long and 36 m high. For each course there is a separate super-structure. Each of the support structures converts three stripes of road transport. I do calculation of internal forces both manually and in Scia Engineer. In the thesis is drawings, showing the gradual construction, diagram of prestressing and reinforcement.

Static Analysis of Structural Elements of Glass
Hořký, Radek ; Gratza, Roman (referee) ; Kytýr, Jiří (advisor)
They analyzed the various factors affecting the design or evaluation of structural glass. Within evaluation of structural glass element is checked selected concepts of linear elastic fracture mechanics. For modeling is used programme system ANSYS based finite element method. The results are compared with the analytical solution.

Stress-strain analysis of the mast in Lelekovice
Vitouch, Matěj ; Vaverka, Jiří (referee) ; Fuis, Vladimír (advisor)
This bachelor thesis is focused on stress and deformation analysis of 3D strut frame. The main goal of this thesis is to create model of strut frame, which is based on TV transmitter in Lelekovice, and his resulting analysis at various degree of static indeterminateness and loads. There is also verification of analytic results by numeric method in Ansys Workbench.

Design and examination of parameters of the line stock loop for sheet metal processing
Novák, Tomáš ; Šebek, František (referee) ; Kubík, Petr (advisor)
Master thesis is focused on determination of stress and deformation state of metal sheet in stock loops of non-standard dimension. The main goal was creating numerical model and de-termination of maximal possible stock of metal sheet for all requested parameters. The problem was solved using Finite element methods in the software ANSYS. Results were handed to ŽĎAS, a.s. corporation, where they will be used for design of the lines for metal sheet proces-sing of non-standard dimension. Another goal was estimation, how the residual stress in metal sheet can effect the observed stress state.

Topology optimization of movable, fixed and based plate of electromechanical injection-moulding machine
Kecík, Samuel ; Halabuk, Dávid (referee) ; Návrat, Tomáš (advisor)
The master thesis deals with the design of geometry of plates of the injection molding unit using the FEM tool Topological Optimization. The reason for this is to reduce the weight of these components, which is beneficial in the transport and assembly of the injection molding machine. However, the final models of geometry of plates must meet certain requirements in terms of the limit state of deformation, the limit state to the critical value of the equivalent stress. This condition involves both limit state of elasticity and limit state of fatigue. Computational modeling and also Topological Optimization are performed in ANSYS Workbench.
