Prestressed frame concrete structure
Duranová, Anna ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The Bachelor Thesis deals with designing a single-span frame structure over the riverbed, specifically a bridge for pedestrians and cyclists. Three studies of the single-span bridge, including their evaluation, were carried out. Subsequently, the variant of the single-span frame bridge with a parabolic deck was selected and drawn up. Dimensioning of the prestressed concrete deck and the reinforced concrete props was performed according to the limit states. The load effects were processed in the Scia Engineer software, and the calculations were made in MS Excel. The calculation procedure adhered to valid standards and regulations.

Traffic situation in the city centre of Havlíčkův Brod and its solution
Tobek, Miroslav ; Lýsek, Tomáš (referee) ; Smělý, Martin (advisor)
The aim of this diploma thesis is the solution of the traffic situation in the city center of Havlíčkův Brod. Mainly the ground road number II/150 adjustment, which consist in the modification of the two-way traffic to one-way traffic organization in the streets Dolní, Žižkova and Na Ostrově by using the analogy of a roundabout layout, is solved within this thesis. All mentioned modifications simplify the traffic situation, improve the orientation and increase the security and the traffic flow mainly in relation to pedestrians and cyclists. Another part of this thesis is focused on revitalization of the public spaces in front of the community center called Ostrov and junction of existing cycle tracks situated on the both banks of the Sázava river. In relation to this topic the adjustment of rainwater sewerage system, low-voltage above ground network, public lighting, communication electric cables, fire brigade signal lights and low-pressure gas pipeline is also solved.

One span cable-supported bridge
Kučerka, Ján ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The theme of this bachelor thesis is the design of a footbridge across the river. The design is processed by two options. The chosen option is designed as a cable-stayed construction supported by cables. Bridge is designed as perpendicular with total length 66,225m. Superstructure is made by prestressed monolithic deck suspended by cables from sloping pylon. Considerable part of the thesis is devoted to creating a so-called initial state. The calculation of internal forces was done by calculation software Scia Engineer 2018. The design of prestressing force, assessment of ultimate limit state and serviceability limit state were done by hand according to the valid standards and regulations. Bearing capacity assessment of pylon was solved by IDEA StatiCa 9 software and some results were verified by hand. The thesis disregards rheological effects and stages of construction.

Arch bridge across the valley
Velešík, Marek ; Zlatuška, Karel (referee) ; Nečas, Radim (advisor)
The main focus of this master thesis is the design and assessments of the bridge structure consist of a stress ribbon supported by a steel arch. Three preliminary studies of pedestrian bridges above the valley were created and the one with semi-through deck supported by arch through cables was chosen to detail processing. This thesis includes a chapter, which deals with finding the ideal shape of arch. The computational beam model for the analysis of the structure was created in software Ansys Mechanical including the construction stages. The correctness of the computational model was verified by the secondary model created in the software Midas Civil. For evaluation of the structure in crosswise direction was created slab model in software Midas Civil. The structure was evaluated considering the ultimate serviceability state and ultimate limit state according to currently valid standards. The thesis also includes dynamic analysis.

Brno Trade Fairs Future
Kousal, Petr ; Hybská, Bohumila (referee) ; Sedláček, Michal (advisor)
Brno will continue to be the city and the centre of the fairs. The historical part around the pavilion A is opened to public and the fairs are concentrated around the pavilion Z, where a new city entrance is planned within a linear park, also a new pavilion and a superstructure with residence of BVV is planned. Newly, the terminal Lipová is designed with the cableway station, which is not only an attraction over the valley of Pisárky, but also represents a form of transport to the campus Bohunice and back to the trade fair center. The design of an exhibition pavilion is situated in a part of Brno-Pisárky, in western area of BVV. The Pavilion contains an exhibition hall and an entrance edifice on a new axis directed from an Anthropos over an superstructure on a significant pavilion Z. The entrance edifice in a central of pavilion is surrounded by exhibition area and its centre is plaza with natural woody plants and colonnade. Entries are leaded on galleries on this level. Galleries are opened into the exhibition hall. A restaurant has a specific view on the dominant-pavilion Z. A visitor goes through the plaza and descends on monumental stairs to the pavilion Z into area of BVV in a primary direction. The visitor descents from the plaza over each galleries to the exhibiton area in a secondary direction. The proposal offers to the visitors and exhibitors not only gathering outdoor relaxation area on the plaza, but moreover interesting experiences from galleries. The total built area of the pavilion is almost equal to the exhibition area, because the design creates the entry level on the third floor. The new building meets the requirements of modern exhibitions and will be used for social and educational events - balls, weddings, conferences, cultural events - concerts, theater, opera performances and sports events. The Pavilion will be visited by inhabitents of all ages not only from Brno, from near and distant surroundings, but also by visitors from abroad.

Overcoming the barriers
Kudelová, Barbora ; Stráský,, Jiří (referee) ; Marek, Jiří (advisor)
Showing the barriers in the city, which inhibit a human in its movement along the landscape. Bunch of barriers at one place can signify a problem for a human to overcome. Marking these places is also showed below the prize map which illustrates from the economic point of view the problem exists at that place and the place is not that permeable as it should be. After marking the problematic spaces and their overlook in the real world there follows a choice of one place and its particular solution. Verifying the reasons why overcoming especially this place, what are the reasons for connecting it, analysing the areas on both sides, pointing out the place of connection and the way to solve the pedestrian bridge and finding the conceptual principle which is the support for the construction principle.

The Footbridge
Rusňák, Marek ; Šmak, Milan (referee) ; Buchta, Stanislav (advisor)
The main goal of this diploma thesis is a design and verification of a steel footbridge crossing the river Dřevnice in Zlín. As the basic material steel S355 and for selected members steel S235 was chosen. There are two structural variants designed in the introductory part of the thesis. These variants are then compared and in the next part only selected, more favourable variant, is addressed. The selected variant is a truss footbridge with a bridge deck at the bottom and curved top chords. The bridge deck consists of floor beams and steel plate with longitudinal stiffeners. The span of the structure is 35.0 m, the width of the footbridge is 3.9 m and its height in the middle of the span is 4.2 m.

Brno brownfields by the Svitava river
Žáková, Dagmar ; Ležatka,, Lukáš (referee) ; Májek, Jan (advisor)
The theme of the diploma project is urban contemporary urban structure in the City of Brno. The main purpose of the selected brownfield is understanding the revitalisation of the city and gets the maximum benefit and to demonstrate the viability of the proposed development and its economic characteristics with the surrounding residential. Proposed is the public space, park and streets in this structure. The territory is located in the Brno-Husovice, near the river Svitava and surrounded by several decaying brownfield. My task was to find the right key to understand this whole area which includes the former object called motorárna - Zetor and find out the ideal solution for the future use of the complex and link it with existing structure to create functional urban organism. Currently, there is a chaotic and heterogeneous structure, which has a negative impact on the surrounding area, which is given by that the area and the surrounding buildings are isolated and hidden behind the unsightly walls. The territory is almost impenetrable, inside the area completely and the natural throughput to the river and partial recreation was supressed. With my project I was trying to create place, which will offer different city urban structure and activities for all day long. In such a place people will met and they will live, work and recreate there and use the river Svitava the right way.
