Pedestrian bridge in Staré Město
Němec, Martin ; Zich, Miloš (referee) ; Koláček, Jan (advisor)
Bachelor’s thesis “Pedestrian bridge in the village Staré Město” is focused on reinforced concrete of pedestrian bridge for walkers and bikers. The pedestrian bridge we can find on the river called Krupá. The structure is considered as a frame. The goal of the work is suggest a horizontal part of the frame and supporting wall. Calculations were made in the program called Scia Engineer. Appraisals were made by hand.

The Design of Highway Bridge Foundations
Králík, Michal ; Doněk, Michal (referee) ; Boštík, Jiří (advisor)
Topic of this master`s thesis is founding of the hightway bridge, which is located between Lipník and Bělotín. Thesis is aimed for creating shallow foundation and foundation on piles and choosing which option is better. All evaluations have been made without specialized software and than compared with GEO5 results. Better solution will be completed with procedure for construction and drawing documentation.

Steel load-carrying structure of production hall with bridge crane
Štulrajterová, Terézia ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
This bachelor thesis deals with the design and assessment of a steel load-bearing structure of a two-aisle production hall. That hall has a rectangular ground plan of a width 32 m (20 + 12 m) and lenght 54,54 m (9 modules distanced 6 m from each other). The main aisle is 10 m high and inside is located a overhead crane with carrying capacity 5 t. The second aisle is used as a storage area for materials that have already been produced. The skeleton of production hall is made of a ten transversal bindings. Lattice trusses are hinged mounted on constraint pillars of solid poles. The hall is situated in the north of the Czech Republic in the city of Děčín.

Static solution of the ceiling structure of apartment building
Habanec, Kamil ; Nečas, Radim (referee) ; Zich, Miloš (advisor)
The Bachelor thesis deals with the static solution of the ceiling construction of an integrated apartment building. The aim is to design, or change the sizes of the projected structures in the submitted project, to ensure the interruption of thermal bridges and protection against foot noise. Subsequently, their static solution, dimensioning and assessment to marginal states. The elements intended for the solution are ceiling structures above the second upper floor, beams, a connecting staircase and a column. The calculation of internal forces was performed in the student version of SCIA Engineer 20.0 with a comparison of values on an independent simplified model. The work also includes drawing documentation for the aforementioned elements. The calculation was carried out according to the applicable standards and principles.

Diagnostics and Maintenance Design
Černoch, Adam ; Pohanka, Martin (referee) ; Kudrna, Jan (advisor)
In the text is given entry of visual inspection about implementation of the selected section in city of Luhačovice. Into forms were plotted failures of the road, determinated their lenght and surfaces. The following describes the evaluation and the cause of failure. After that is given the design and repair of the road. In the theoretical part is written the classification of failures according to TP 82 „Catalogue of flexible pavement failures“. From the cataloque I chose and mentioned important failures that are manifested in diagnosis section. Finally, describes the principles of planning and design of maintenance or repair.

Frame bridge
Kapsa, Štěpán ; Velešík, Marek (referee) ; Koláček, Jan (advisor)
The work deals with the design of a single-pole frame structure of a road bridge, which is based deeply on piles. Due to the size of the span of 26 m, additionally prestressed cables are designed in the supporting structure. The structure is analyzed by a three-dimensional bar model and assessed for serviceability and load-bearing limit states in the longitudinal and transverse directions. Part of the design is a study of the influence of supporting the computational model and a comparison of the effect of active and resting earth pressure on the structure.

Computational modeling of radial hydrodynamic bearings for water machines
Pokorný, Jan ; Šimek,, Jiří (referee) ; Návrat, Tomáš (advisor)
The aim of this thesis is to calculate the stiffness and damping coefficients for radial hydrodynamic bearings. Cylindrical and lemon hydrodynamic bearings are considered. The solution to this problem mainly depends on the hydrodynamic pressure in the bearing. The numerical solution of the Reynolds equation is used to calculate the pressure. The effect of variable viscosity and density of the lubricant due to temperature changes is considered. The static equilibrium position of the journal centre is also solved. The stiffness and damping coefficients are determined using small amplitude journal motions about the equilibrium position. Three methods for determining these coefficients are presented. The outcome of this thesis is an algorithm for the calculation of stiffness and damping coefficients for cylindrical and lemon bearings. Results for lemon bearings are presented and comparison with the commercial software DynRot BR is made. The benefit of this thesis is the creation of an algorithm for the calculation of journal centre equilibrium position, a new way of incorporating the temperature changes in the viscosity and the density of the lubricant, and the modification of a method for calculating stiffness and damping coefficients based on experimental analogy.

Unbound mixtures to the pavement base layers
Žůrek, Jakub ; Hýzl, Petr (referee) ; Stehlík, Dušan (advisor)
The subject of this bachelor’s thesis is the possibility of using alternative materials in base road layers. Specifically It‘s about different granular material from mines (fraction 0/22) and recyclate, the possibility of their their classification within the used base layers and assessment of their suitability for specific structural layer. The thesis subject is also assessment of suitability of laboratory tests currently used in the Czech Republic and is trying to deal with the question whether these tests are ideal or not. The theoretical part summarizes the currently used base layers, their properties, technology of their implementation and It explains the current testing system. The aim of the thesis is to define mechanical properties of the examined materials, compare them and evaluate them.

Design of reinforced concrete structure of administration building
Blažek, Jan ; Girgle, František (referee) ; Šimůnek, Petr (advisor)
The subject of this thesis is the project of the foundational board and of reinforced concrete walls of the underground office building with respect to the limit state of crack width. There is designed the execution of joints of various parts of the construction against infiltration of groundwater into the interior. The drawing documentation of designed parts is performed there. In the theoretical part, there are logged the design principles and implementation of the white tubs.
