Pedestrian Footbridge over Railway Station
Hurych, Marek ; Štrba, Michal (referee) ; Brosch, Petr (advisor)
The diploma thesis deals with design of loadbearing stell structure of a footbridge across the railway station. Footbridge is situated in the city centre of Brno with total length of 135 meters. For comparison, three bridging variants are predesigned and a varints comparison is made. The selected option was developed in greater detail. It is an arched structure with a semithrough bridge deck and adjacent span with support of oblique column. The main loadbearing structure consists of a pair of pin-supported arches inclited to each other at an angle of 11°. Arches support beams with susperder, the beams are conected by ortotropic steel deck. All load-bearing elements are designed from S355 stell. Spatial rigidity of the structure is ensured by tilting of the arches and by truss bracing at the top of the arch in combination with rigid struts of arch. Spatial rigidity of the superted deck is ensured by ortotropic steel deck.

Plan curved cable stayed pedestrian bridge
Müller, Radek ; Kaláb,, Pavel (referee) ; Koláček, Jan (advisor)
In my thesis, I created a study of plan curved cable stayed pedestrian bridge. As the main construction material is used prestressed concrete. Suspenders and railing are made from steel. The footbridge has a length of 130,00 meters and a width of 3,70 meters. The plan shape of the structure is composed of two oposite arches. Bridge deck is made of box girder. The bridge deck is single-side suspended on two concrete pylons with a height of 39,00 m. Pylons are supported by suspender.

Static analysis of cable
Pőthe, Péter ; Kytýr, Jiří (referee) ; Vlk, Zbyněk (advisor)
This bachelor thesis deals with the static analysis of suspension cables of the suspension footbridge. The processing was done as a manual calculation as using the program system RFEM for a static finite element method from company Dlubal. The task was to determine the geometric shape of cables and the real position of suspenders, which we get after the construction of the bridge. The results were then compared with each other.

Revitalization Program of Floral Garden in Kromeriz
Holý, Martin ; Františák, Luboš (referee) ; Sochor, Jan (advisor)
The project respects the original conception of the garden to create space closed against surroundings. In the Holland garden I create one building that contains galery, café, bookshop and education center. The groundplan shape results from the axes of the Floral Garden. The Holland Garden is a changing space, variable is the inner disposition of the building as well. In the south part I project glasshouses, outdoor patches, a workshop building, water atractions and a voliere for keeping birds. The groundplan solution of this part goes out from the groundplan of the building in the Holland garden.

Production hinge saddle motorcycle
Hanych, Libor ; Peterková, Eva (referee) ; Lidmila, Zdeněk (advisor)
The project elaborates the design of technology production of the hinge used for fixing saddle motorcycle. The hinge is manufactured from 1 mm thick construction sheet steel 1.0038 in production run of 50 000 pcs/year. A technology of shearing and bending at progressive die tool was selected from various options as the most suitable technology of manufacturing. Based on the literature study of shearing and bending technology, an optimal production process of hinge was designed. After technological, structural and control calculations the tool was designed and the technical documentation was elaborated. The eccentric press LKDR 200 made by ŽĎAS company was selected for the production. This press complies in terms of required forming force and the dimensions of the tool. Using the economic evaluation, the production costs for one hinge were calculated in the amount of 18,5 CZK. 35% profit of the company is included in the price. According to the calculated turning point, the production becomes profitable after 24 187 piece being manufactured.

Footbridge across the Berounka
Zlatuška, Karel ; Romportl, Tomáš (referee) ; Stráský, Jiří (advisor)
The diploma thesis deals with design of plan – curved footbridge over Berounka river near the town of Čivice. Three different options were developed. First option includes a single – beam prestressed integral construction with haunches. The second option includes suspension footbridge construction, where the bridge deck is suspended at one side. In the third option the main span is built from concrete segments. Those are suspended on a pair of steel arches. The access ramps are cast – in – place, and they are supported by round steel piers. This variant was finally chosen as the best one and it was further processed. The construction was analyzed with Scia Engineer 2015 software, considering the construction process. The footbridge was loaded with dead loads and live loads including traffic and thermal actions. The internal forces were calculated and the construction was assess to the serviceability and ultimate limit states. In terms of serviceability, stress in concrete sections and deformations were checked. In terms of the ultimate limit state, the ultimate load capacities were calculated. The steel arches and piers were checked for possibility of loss of stability by buckling. The loss of stability was also checked by the software. Finally the dynamic behaviour of the construction was assessed, especially the harmonic excitation response. Then the construction plan and the drawings were made. The drawings include overview drawings and detailed drawings.

The Active Bonnet Hinge
Galda, Michal ; Růžička, Bronislav (referee) ; Brandejs, Jan (advisor)
This thesis deals with designing the construction of an active bonnet hinge, tuning the kinematics and appropriate proportioning of individual parts of the hinge. The thesis consists of two main parts – the first part is an analysis of the current state of knowledge and the second part presents a designing the construction. The active hinge should serve as a safety element in automobiles to minimize consequences of head injury suffered during the collision of a pedestrian with an automobile.

Tail Units
Dula, Jan ; Mališ, Michal (referee) ; Urík, Tomáš (advisor)
In this bachelor´s thesis is created a survey of constructive solutions and lay-out of horizontal tail unit, solutions of horizontal stabilizer attachment and ways to control the elevator. In the introductory part the term which is used in this thesis are briefly explained. In the following part the possible configurations of the tail units are listed. From these configurations, some solutions are selected and they are closely classified. Any of these solutions provides a short description of the elevator control, the advantages and the disadvantages of this solution, an overview of selected horizontal stabilizer attachment and their detailed description.
