Ocelová konstrukce zimního stadionu / Steel Structure of a Winter Stadium

Lobreis, Jan January 2017 (has links)
The work is focused on assessing the structure of urban winter stadium, which will be located in Brno - Komarov. Winter stadium is designed according to standarts of ice hockey with a capacity of approximately 7 000 spectators. Of the 5 850 seating, 1 050 stalls and 100 in the VIP areas. Construction of hockey stadium is made of steel and steel-concrete columns, which together with composit transverse beam, reinforced concrete slab and bracings provide rigidity. Columns are supported by a set of bored piles with capitals. Roofing of the main part of the winter stadium is designed using a flat space frame having a maximum height of 4,5 m. Roof for entrance halls are design by a system of truss girder and purlins, which are hardened bracings to increase spatial rigidity. The structures are made of steel S 355 and concrete C 25/30. For designing steel structures was used software Scia ENGINEER and IDEA RS. Steel columns and composit beams are calculated by hand calculation. The total length of the hockey stadium is 111,5 meters, width outside the entrance hall is 82,02 m and the total width at the entrance hall is 96,85 m. The height of the building at the highest point is 25,6 meters.

Tvorba integrovaného systému řízení jakosti na bázi ISO 9001 a ISO 14001 v konkrétní firmě / Creation of the integrated system of the quality management on the base of ISO 9001 and ISO 14001 in the particular firm

CHVÁTAL, Jiří January 2012 (has links)
This diploma thesis with the title Creation of the integrated system of the quality management on the base of ISO 9001 and ISO 14001 in the particular firm has the target to develop the proposal of the procedure of the implementation of the system of the environmental management according to the norm ČSN EN ISO 14001 and of the quality management according to the norm ČSN EN ISO 9001 in the company LAMIVEX s.r.o. To reach the target it was necessary to hold a conversation with the senior management and the employees, to observe their every day activities and to make the internal audit. The following step was to elaborate the gained information and to create the documentation according to the norm ČSN EN ISO 14001 and the norm ČSN EN ISO 9001.

Hodnocení konstrukcí průmyslových objektů podle ČSN ISO 13822 / Assessment structures of industrial buildings in terms of ISO 13822

Kirschbaum, Adam January 2016 (has links)
This diploma thesis deals with the evaluation of the constructions of the industrial buildings according to the ČSN ISO 13822 Standard. In the first, theoretical part, the procedures of research and evaluation of existing reinforced concrete constructions based on the ČSN ISO 13822 and ČSN 73 0038 Standards are described. Further, the theoretical part is focused on the diagnostic methods used during the evaluation of these constructions. The practical part focuses on the evaluation of the three industrial reinforced concrete buildings. It includes information about the building, the description of defects, diagnostics and the appraisal of measuring. The last part deals with a static calculation of selected parts of the supporting construction.

Testování částí oděvu pomocí tepelného manekýna / Measurement of clothing sets by means of thermal manikin

Hanzlík, Martin January 2017 (has links)
This diploma thesis is focused on the experimental determination of thermal resistance of the gloves and their combination in the layering system. The measurement was based on procedure specified in the standard ČSN EN 511 by means of thermal manikin. The thesis begins with the description of heat transfer mechanisms, description of glove materials and measurement methodology. The body of paper consists of the measured data analysis and equation design for determination of the glove layering system thermal resistance. At the end of the thesis, these equations are evaluated and it has been shown, that the thermal resistance of glove layering system cannot be precisely determined by the calculation, and it is necessary to measure the whole three-layer system.

Nejistoty měření průtoku páry / Steam Flow Measurement Error Analysis

Barabášová, Iveta January 2017 (has links)
The thesis deals with analysis of measurement uncertainty. The theoretical knowledge presented in opening chapters is applied on indirect steam flow measurement by orifice plate. Calculation of steam flow is based on knowledge of pressure difference value, static pressure value and temperature. The data are acquired by experimental measurement in laboratory. The mass flow rate uncertainty is determined by normalized procedure (according to standard ČSN EN ISO 5167) and by detailed error analysis (according to standard ČSN ISO 5168) for comparison. Whole numerical computation employs python programming language in Spyder environment. Other computation result is steam consumption of washing cycle.

Příprava materiálů pro výuku softwarového nástroje Eplan / Development of the materials for teaching the Eplan software tool

Benetka, Tomáš January 2018 (has links)
This master’s thesis deals with the development of materials for classwork using EPLAN software tools for "XEPL" course. The introductory part describes issues with design in electrical engineering, with an emphasis on the formal aspects of project documentation standards and software tools for design support. Further in the thesis, there is an introduction to the EPLAN software environment. The EPLAN environment modules are presented one by one and the EPLAN Education software is introduced. The next part of this thesis involves a model project in designing electric installation of car washer in the EPLAN Education. The last part of this thesis includes a set of exercises based on this model project, where basic functions of the EPLAN software and their uses are presented.

Počítačová podpora projektování datových rozvodů - projektová laboratoř / Computer support for data distribution design - design laboratory

Benešová, Lucie January 2010 (has links)
This thesis is concerned with data wiring infractructure. In the theoretical part the basic technology of the LAN networks is described as well as its parts, such as HUB and switch. Various types of transfer paths used in data wiring are briefly mentioned. They included coaxial cable, which were then replaced by shielded twisted pair and in future the fibre optics cables will be used instead. The shielded twisted pair operates on structured cabelling, which is guided by central principles in designing, which then can guarantee 15 years of good service. The most used cables 5e and 6 are described. The next chapter describes the endings of cables and connectors as well as the principles of patch pannels and patch cables. The following parts focus on the fibre optics networks, because they are the networks of the future. The types of fibre optics cables are described together with networks standards, the minimal fibre radius and innovations such as WDM or micropipes. There is also a resume of the ČSN norms, which are important for this thesis, concerning issues of the ways how to lay cables, placing of the communications etc. In the practical part, the various softwares for designing data wiring infractructure are studied and compared. As the most convinient for student proposals the AutoCAD Electrical 2011 has been chosen. This design software is studied from the point of view of its user interface and basic rules of behaviour. The functions of the menus and pripary settings are described. In the last part of the thesis the lesson is provided. The lesson should give students basic information and opportunity to design a basic data wiring infrastructure for a building.
