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.

Static analysis of suspension bridge variants
Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor's thesis deals with the static analysis of individual models of suspension footbridges. A manual calculation of the cable was processed. The actual position of the cable was determined by calculation. The manual calculation was compared with the RFEM calculation program. Furthermore, the models were loaded with manually calculated loads. The bachelor's thesis deals with the influence of pylon deflection on the global deformations of cable and bridge deck during individual load cases and combinations. For one of the models, the optimization of construction was processed.

Cable-supported bridge
Kovářová, Marika ; Bezručová, Kristína (referee) ; Nečas, Radim (advisor)
The theme of the thesis is to design a pedestrian bridge over a river. Out of two possible designs, the cable-stayed construction was chosen. The deck of the bridge is designed as a monolithic construction supported by cables from two inclined pylons. Two models were developed for the calculation of internal forces: a strut model for the longitudinal direction and a plate model for the perpendicular direction. These calculations were checked up by Finite Element Method (FEM) in SCIA Engineer 2017 software. Considerable part of the thesis was dedicated to the creation of so-called initial state. The design of the prestressing force and the evaluation of ultimate limit state and serviceability limit state was made in accordance with the codes currently in force. Small part of the theses is dedicated to the verification of the load bearing capacity of the pylon on the combination of normal force and bending moment with a subsequent verification in the software IDEA StatiCa9. The pedestrian bridge of 64,150 m length is considered as a perpendicular.

Pedestrian Bridge
Hibš, Daniel ; Kocourek,, Petr (referee) ; Stráský, Jiří (advisor)
This diploma thesis deals with the design of a new bridge construction over a multi-lane communication. The converted road is a pedestrian and biking trail connecting significant agglomerations. Three studies were worked out in this thesis and the C variant was selected for further detailed processing. It is an unsymmetrical suspended bridge with a cast-in-place deck. In the section above the communication, the bridge is made up of prefabricated segments. Suspension of the structure is made of two sloping pylons forming a V-shape. The analysis of the construction was carried out in the MIDAS Civil program, where a complete model of construction was entered, including a subsequent estacade. The model describes the construction process and includes creep and shrinkage of the concrete. The traffic, temperature and wind loads were used. The design was assessed for the ultimate limit states and serviceability limit states. The assessment was carried out in the IDEA StatiCa program, supplemented by manual calculations. The static calculations also include assessment of the harmonic response. Subsequently, overview drawings, detailed drawings and visualizations were developed.

Gmont Cable s.r.o., cable manufacturing plant
Vacek, Václav ; Vostrejž, Dušan (referee) ; Boleslavská, Yvona (advisor) ; Sobotka, Jindřich (advisor)
The bachelor thesis deals with the drawing of the industrial plant, namely the work is focused on the part of the administrative and the employees' background. The assignment of the atelier work is a newly built factory of Gmont Cable s.r.o., which is focused on the production and installation of cable harnesses, cables and conductors. The proposed object will contribute to the growth of the company, which is constantly developing and increasing its capacity. An ambitious investor also includes further product development by cooperating with Brno R & D institutions. The object is designed in rectangular shapes that copy the plot and the surrounding area of the industrial zone. The building is divided into two parts, a two-storey office building with facilities for employees and a production hall. Both of these objects are at the same height level that are joined together in the western part. From the eastern side, these two objects divide the half-closed atrium, which is open to Těžební Street. Thanks to regular column rafters, the entire building is designed as a prefabricated reinforced concrete skeleton, covered with kingspan sandwich panels and a partially glazed facade made of profiled glass call profilit that illuminates the entire interior of the building. The entire building is wheelchair accessible and offers plenty of space for both staff and visitors to park.

Multi-Conductor Model of Communication over Outdoor Power Lines
Franek, Lešek ; Steinbauer, Miloslav (referee) ; Vozňák, Miroslav (referee) ; Fiedler, Petr (advisor)
PLC - power line communication is not new. It has been known for many years. But It never be used in massive scale. There were only sporadic applications, for example ripple control system HDO used in the Czechoslovakia. PLC currently experiencing a renaissance thanks to the advent of Smart Grid. PLC offering relatively low bit rates and relatively unreliable transmission, but these disadvantages compensates very low costs to build a communication infrastructure and it offers specific functionalities for Smart Grid. The question is whether the declared parameters will be met in the real world. This thesis tries to find an answer.

Bridge on a ramp
Otevřel, Rostislav ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
Thesis describes the design and assessment of a plan view of a curved road bridge, which is a part of an elevated crossing transferring directional divided communication and tram line of public transport in Brno. There are four variants of cross sections designed, from which is selected bicameral cross section with arched angled bottom plate, which should be aesthetically pleasant to impress in an urban environment. Static calculation is processed and design is assessed by current European standards. Then clear and detailed drawings, the process of construction and visualization of the bridge are processed.

Migration of telemetric narrowband radio networks to the IP standard
Stupka, Richard ; Lattenberg, Ivo (referee) ; Maršálek, Roman (advisor)
This bachelor’s thesis deals with the innovation of narrowband telemetry radio networks to the IP standard. This involves the modernization of old radio data networks that do not use the IP standard or are nearing the end of their life cycle. Renovation has a great benefit in terms of performance, reliability, and security. This modernization is achieved through migration, which means upgrading the old technologies to new ones. The objective of this thesis was to develop theoretical analysis and a technical procedure for network migration. It was deals with the currently used technologies and utilized components, parameters of individual network nodes, the actual design of the migration technical solution and network preparation. After the analysis and technical solution for migration had been performed, the proposed migration solution through simulated operation in a laboratory environment was verified. Based on the obtained information, configuration files for real-world usage were created, radio signal coverage in the field was verified and the communication capability in the newly built RipEx2 network was tested.
