Concrete ribbed slab
Dvořák, Vít ; Perla, Jan (referee) ; Strnad, Jiří (advisor)
The bachelor thesis deals with a design of monolithic reinforced concrete, line supported and cross reinforced slab and a design of supporting reinforced concrete ribs. The plan of the slabs is rectangular and one time bent. The content bachelor thesis is calculation and design of reinforcement of slab and ribs. For the calculation was used software Scia Engineer 14 and was checked by manually calculation. The slab is located in the first floor of polyfunctional house. Other parts of the object are not covered by the thesis.

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.

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.

Roof construction of extinguishing systems
Mikulincová, Denisa ; Šulák, Pavel (referee) ; Požár, Michal (advisor)
The bachelor thesis deals with the assessment of the existing reinforced concrete structure of the roof on the fire extinguishing facility. The analysis is performed using the Scia Engineer program. A new design is also proposed. Roofing is done with a ribbed board. Part of the thesis is also an analysis of the possibilities of solving ribbed boards in the Scia Engineer program.

Reinforced concrete structure of office building
Lagiň, Juraj ; Šulák, Pavel (referee) ; Girgle, František (advisor)
The Bachelor thesis deals with structural solution and comparing of the two variants of reinforced concrete slab structure of administrative building. First variant, designed like a slab with full section, is being compared with a variant of slab, which is designed like a voided slab by formwork U-boot. The structure is designed and assessed for ultimate limit state in accordance with ČSN EN 1992-1-1: Design of concrete structures – Part 1-1: General rules and rules for building.

Design and analysis of electromagnet
Macek, Pavel ; Skalka, Miroslav (referee) ; Vítek, Ondřej (advisor)
This work deals with a proposal and an analysis of electromagnets. The first chapter is an introduction into solve of the problem. In the second chapter there is a general discussion about basic relations of the electromagnetic field. The third chapter is dedicated to the operation principle and construction of electromagnets and is supplemented with their common classification. The fourth chapter introduces the Finite Element Method and the FEMM programm. The fifth chapter is dedicated to the analysis of the DC electromagnet, the sixth chapter analysis single-phase AC electromagnet. In the seventh chapter there is a review of results of general analysis of both electromagnets.
