Design of the floor slab structure of a tall building
Vintrová, Tereza ; Šimůnek, Petr (referee) ; Zich, Miloš (advisor)
The bachelor thesis deals with the design of the ceiling structure of a high-rise building. The basis for the work was a study of the building with basic floor plan dimensions and heights. The aim of the bachelor thesis is to design a locally supported floor slab with a stiffening core in the middle, as a section of one floor, namely the ceiling above the tenth floor. According to the specified study, a slab model was created in SCIA Engineer to analyze the internal forces based on which the design of the flexural reinforcement of the slab to the ultimate limit state was carried out. The design of the shear reinforcement is based on the internal forces of the 3D model and was done using Schöck Bole with manual verification of the selected column. Non-linear calculation of the 3D model and manual verification of crack widths was used to assess the ultimate limit state. At the end of the work, the design of the circumferential rib variant and the comparison of the two types of slabs was carried out. The work includes a static calculation and drawings.

Comparison of free available software for the calculation of electric network parameters
Dvořák, Radim ; Janík, Daniel (referee) ; Ptáček, Michal (advisor)
The aim of this bachelor thesis is to compare freely available software for calculating the parameters of electrical networks. The first part is used to give an idea how to operate in the programs Sichr, DOC, Spider (xSpider) and ~ SIMARIS design and their evaluation in terms of usability, requirements, graphical interface and controllability. Furthermore, a technical analysis of specific topologies of specified distribution networks is performed in the work. In the second part, the calculation of network parameters was performed using the SW above. Finally, the realized calculations of voltage drops and short-circuit currents using individual programs were compared with each one another.

Design of warm air heating system for low-energy house
Koutník, Martin ; Krejčí, Vladimír (referee) ; Košner, Jan (advisor)
The diploma thesis deals with design of warm air heating and ventilating system for low energy house. Introduction of this thesis is focused on dividing residential buildings by their heat requirement. Then problems of residential building ventilation and possibilities of warm air heating systems including heat recovery are presented. In the next chapter summary of ventilating units with heat recovery and warm air heating units for residential low energy buildings and pasive family houses is presented. Calculation of low energy house heat losses, which is solved, is based on CSN 06 0210, CSN 73 0540 and CSN EN 12831 standards. Design and calculation of warm air heating and ventilation system and ground heat exchangers is also described. Floor heating system, fireplace insert and solar heating system are designed as supplementary systems. At the end of this thesis the control system is presented. Project documentation is enclosed in appendix.

Design of instrument transformers for digital protection relays
Souček, Jan ; Matuška, Marcel (referee) ; Toman, Petr (advisor)
Master’s thesis is concerned with instrument transformers, which are used in conjunction with numerical protection relays. Therefore mainly with protective transformers of class P and transformers dimensioned for transient effects, which are important e.g. for fast differential or distance protections. The introduction includes fundamental notions, quantities and equations, which refers to instrumental current and voltage transformers. Below are mentioned connection diagrams of these transformers applied to specific electrical network types and faults, of which identification is required. These diagrams and faults are supplied with math equations and eventually with phasor diagrams. Noted informations corresponds to the present standards. Task of the next part is to compile requirements for dimensioning of current transformers, which imposes digital protections from ABB, AREVA and Siemens companies. These requirements, which mostly defines the minimal accuracy limit factor or the knee-point voltage of current transformer, are specified for individual protection terminals, eventually for specific protective functions. Part of the thesis is computer program developed as macro in the Microsoft Office Excel program via Visual Basic for Applications programming language. Program uses equations noted in this work and it can be used for quick dimensioning of current transformers for protective terminals from manufactures mentioned above.

Static solution of prefabricated hall
Koníček, Jakub ; Koláček, Jan (referee) ; Zich, Miloš (advisor)
The presented thesis deals with design and optimization of selected structural elements of high-load storage hall skeleton. As a basis for the solution is taken the structure of a real storage hall designed in the years 2017-2018. The structure is designed for minimum weight. For this reason, so-called D-regions are formed on the structure. For the solution of D-areas, general methods of solution, such as STM or nonlinear FEM analyses, are used in the thesis. In the final designed structural elements are compared to the original design of the hall. Thesis include static calculation of 24 m long roof beam V1, static calculation of 24 m long ceiling beam ST1, drawing documentation and technical report. Programs were used for the calculation: SCIA Engeneer 18.1, Idea StatiCa Beam10.1, Idea StatiCa Detail 10.1, RIB Fermo, PTC MathCad and MS Excel.

Heating and hot water of pension
Beneš, Josef ; Formánek, Marian (referee) ; Počinková, Marcela (advisor)
The Bachelor thesis deals with heating system and preparation of hot water for a boarding house building. In the thesis is introduced fundamental systematics of heat line water systems and heating distribution. By the most frequently used materials are identified advantages, disadvantages and possibilities of application. Piping joints are divided according to disassembleability and single options are furthermore described. In the calculating part is analyzed the particular building based on its characteristics. According to this analysis is the building classified from the viewpoint of energetic demands and therefore was determined its “Building envelope energy label”. Based on those and additional data was designed the heating system in correspondence with national regulations. Suggested solution takes in account efficiency, comfort, acquisition and operating costs.

The multistorey office building
Bílek, Tomáš ; Sýkora, Karel (referee) ; Šmak, Milan (advisor)
Design of a new steel structure administrative building in Zlín. Structure is consist of three parts. The part A is designed of three fields in the transverse direction and five fields in the longitudinal direction. This part is two-storey. The part B is designed of two fields in the transverse direction and three fields in the longitudinal direction. This part is six-storey (five-storey). The part C is designed of two fields in the transverse direction and five fields in the longitudinal direction. This part is four-storey (three, two-storey).

The subject of work is design supporting bridge construction at urban area Frydlant across creet Rasnice. This object location is on the local road at cross point 0,079 km. The aim is to propose a vertical structure with one field, proposes to adapt the position in, which is proposed in three variants. It is a variant changes shape supporting structures, the maximum height oh the structure is 0,645m. The first variant is a slab constant rectangular section.The seccond variant is a slab of variable selection with beveled the slope. The third is slope shape of parabole 2. Selected by detail and assessment the first variant was chosen with a longth of bridge 8m. The calculation of load effects is done by computer softwares Scia Engineer 15.3 and compared with a manual calculation according to current standards.
