Reconstruction of the road bridge
Laczko, Zoltán ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
The subject of this thesis is to design a new slab structure instead of the steel concrete slab. The structure of the new load bearing structure is post-stressed cast-in-situ slab with continuous slab structure consisting of three spans. The slab is pre-stressed by monostrands. The load bearing structure is evaluated for first and second limit state too. The construction is modeled in software named Scia Engineer 2011.

Sheeting of Foundation Pit
Vodáček, Ondřej ; Chalmovský, Juraj (referee) ; Glisníková, Věra (advisor)
First part of the thesis talks about pit sheeting in general, including shafts and trenches as well as pits, however pits are the very main topic and therefore described in details. This part also discusses earth pressure and groundwater issues as applied loads, yet only marginally. Second part demonstrates a particular sheeting structure and its calculation. All presumptions are established here, including double-anchored sheet pile wall geometry, spoken earth pressure loads and groundwater loads plus heavy equipment load during a construction. The calculating process is shown using computer softwares (Plaxis 2D, GEO5) and also in a non-software way using just pen and paper. At the very end of thesis an ultimate limit state (ULS) of sheet piles is assessed, software and non-software results are compared to each other and discussed.

Validity of Local Positioning System
Németh, Filip ; MPA, David Prycl, (referee) ; Hanák, Petr (advisor)
The aim of this presented thesis is to verify the validation of LPS, which runs on the principle of wave radiations, UWB technology in particular. The testing protocol verifies the precision of system functions in various places and two diferent altitudes of the pitch. The ultimate precision of monitoring was recorded in the middle of the pitch, vanishing to the sides. In a higher altitude, with no surrounding walls, the recordings from the middle of the pitch were nearly similar to the sides of it. The anchor altitudes of the mechanism affect the overall monitored results. In comparison, the accuracy of tag placed approximately in a plane of anchors was lower than tag placed in a vest of an athlete.

Simulation of circuit breaker maglatch dynamic behaviour
Konšel, Ladislav ; Dostál, Lukáš (referee) ; Valenta, Jiří (advisor)
This work includes the theory of circuit breaker construction and is focused mainly on overload function. It mainly deals with electronic circuit breakers, i.e. equipped with an electronic trip unit. The work is focused on the part of trip unit - maglatch of trip unit. For the purposes of simulation, the geometric model is created. Maxwell program is used for the simulation. The work describes the options for conditions input which are necessary for simulation. Using the distribution of magnetic field intensity and magnetic flux density in the section of trip unit maglatch is determined by the simulation. Furthermore, the force effects acting on the armature of the maglatch are calculated. Force values and the directions acting on the armature are determined by changing the simulation parameters - shift of the armature and coil current. Simulations are performed both for steady-state and for dynamic simulation – movement of armature is taken into account. The supply source for the maglatch is created by an external circuit.

The Structure of the Atypical Family House in Vrchlabí
Vondráček, Vít ; Hron, Lukáš (referee) ; Šmak, Milan (advisor)
The subject of master’s thesis is design and assessment of steel load-bearing construction of atypical family house in Vrchlabí. Structure is designed as multi-storey steel structure, cooperating with stiff concrete core. The design was considered in four different options which combines possibility of using steel, steel and timber with different way of stiffness for whole structure. There is also composite steel-concrete alternative floor trimmer for selected option. Design and assessment was conducted in accordance with the applicable standards and by using software Scia Engineer.

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.

Ejection mechanism automotive starter pinion
Sláma, Miloslav ; Janda, Marcel (referee) ; Hájek, Vítězslav (advisor)
The thesis describes ways ejection pinions automotive starter and evaluation of the advantages and disadvantages of each solution. The first chapter deals with the principle of operation of DC motors and starters parameters. In the second part, the individual systems are theoretically discussed in terms of design and their advantages and disadvantages. The third part is focused on the most common system, which is analyzed in terms of mechanical and electrical reliability. The last point of the work is to design an experimental analysis Reach starter pinion.

Design of prestressed bridge structure
Otáhal, Ondřej ; Rybák, Vít (referee) ; Klusáček, Ladislav (advisor)
Diploma thesis deals with design of a road bridge over Husí potok in Hladké Životice. The supporting structure of the bridge is designed in three variants, one of which is selected variant post-tensioned slabs. To address the internal forces is used computing software Scia Engineer. In the structural analysis of the bridge structure is assessed at the ultimate limit state and serviceability by European standards – Eurocodes. For chosen variant is prepared drawing documentation and visualization.
