The two-track railway bridge
Loučka, Miroslav ; Karmazínová, Marcela (referee) ; Puchner, Josef (advisor)
Master´s thesis describes the design of the railway bridge in Ústí nad Labem. Length of the structure is 200.00 meters, the height of the structure is 32.61 m and width of the structure is 12.10 m. Main structural system is composed of a spatial strut-frame structures. The bridge carries an important railway stations between Usti nad Labem Západ, Usti nad Labem Střekov. Part of the proposal is a footbridge for pedestrians.

The footbridge across the track
Mojžíš, Jan ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
This thesis describes the design of steel structures footbridge over the track in Havířov. The total length of the bridge is 101.6 m footbridge consists of four parts. The basic structural system of the first part of the beam is solidified arc. Other parts are made girders. Free bridge width is 3.2 m Footbridge will be used to connect local area Havířov - Šumbark to the train station.

Footbridge in Nova Karolina in Ostrava
Havelka, Jiří ; Nečesal, Petr (referee) ; Marván, David (advisor)
The topic of the master’s thesis is a design of steel structure of footbridge. Footbridge goes across the roadways and railway. It is a design of a new structure in Nová Karolina in Ostrava. Span of footbridge is 200m. The footbridge’s superstructure is two steel arches angled toward each other and fixed to the foundation blocks. The supporting beam of the bridge deck is connected to the arch by tie-rods. The deck beam is a welded box section. The tie-rods are arranged to the V-shaped system. Deck of footpath is semi through type and orthotropic. The arches are connected at the top by lateral bracing. Lateral bracing is Saint Andrew's Cross type system.

Design of the footbridge over the railway
Mertová, Eliška ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
The aim of this bachelor´s thesis is a design of a new footbridge over the railway instead of an existing reinforced concrete pedestrian bridge in a compound of the cement factory in Mokrá at Brno. The footbridge is used to the transfer pedestrians over the mentioned train. The work is composed of the design of the pedestrian bridge as a continuous frame structure, including making a model of the bridge for an analysis of internal forces, design and checking the structure for the ultimate and serviceability limit state. A calculation of load effects is processed by the computer software Scia Engineer 2013. The construction stage analysis wasn´t applied in the structural calculations.

Analysis of the steel structure of the bridge by FEM to the action of static load
Skorunka, Ondřej ; Hradil, Petr (referee) ; Salajka, Vlastislav (advisor)
The structures of bridges are one of the most demanding engineering structures. They fulfill an important social and economic role in the development of the given territory. From this perspective, it is necessary to pay close attention to the process of design, analysis, realization and service. This thesis deals with the static analysis of spatially curved and asymmetrical suspended foot bridge for pedestrians and cyclists. The first part is devoted to the analysis of structural deformation, while the second part is focused on the analysis of selected parts of the structure in terms of its stress.

Sport Centre Královo Pole
Kostíková, Lenka ; Teplý, Vladimír (referee) ; Odvárka, Antonín (advisor) ; Štěpánek, Ladislav (advisor)
The theme of my project was design of facilities for Sport centre in Brno, Královo Pole. The plot is situated near the existing sport complex on the Vodova street. Part of the designed centre are 4 objects. The main building is the object with facilities for existing outdoor ice rink. There are changing rooms for visitors and offices for management of the centre. In another building there are cafe, shops and the facilities for the football stadium. Each object is accessible for wheelchair users. All objects are two-storey. Objects are connected by footbridge at the level of the 2nd floor. The footbridge is not only for wheelchair access to all buildings, but also like view point of the ice rink. The objects are designed as a frame construction made from steel profiles HEB. The shape of the building creates several equal blocks, which are differently assembled at each object. The footbridge is made from steel columns. The facades of all buildings are covered with larch wood.

Cable-supported pedestrian bridge
Tichavská, Andrea ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The scope of the thesis is the design of a cable-supported pedestrian bridge. The structure of the pedestrian bridge is formed by concrete bridge deck supported by external cables. The transmission of the prestress is provided by steel elements. The main goal of this project is the design of prestressed concrete bearing structure. Construction phases will not be taken into consideration.

Pedestrian bridge formed of a stress ribbon structure
Sedlářová, Lucie ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The theme of this bachelor thesis is a design of a footbridge across the river. The thesis deals mainly with static solution of footbridge formed by a concrete stress ribbon. The calculation of internal forces was done by using calculating program Scia Engineer. The other calculations for assessment and design of reinforcement were done by hand according to valid standards. The thesis disregards stages of construction and rheological effects which would affect the construction.

Experimental and numerical verification of vortex-induced vibration of hangers on the footbridge
Urushadze, Shota ; Pirner, Miroš ; Pospíšil, Stanislav ; Král, Radomil
The paper deals with vortex-induced oscillations of footbridge hangers at a very low wind speed. The two-spans (2x50m) reinforced concrete structure with the central pylon (25m height) is designed as the harp system of hangers with circular cross-section. The oscillations were observed at the low wind speed and the high double amplitudes has been measured. The wind-excited deformation shape corresponded to the 6th, 7th and 8th natural modes of a hanger. The individual hanger as well as thein group were analysed to estimate the dynamic response, possible aeroelastic vibration and special interference or coupling effects. It also includes proposal for the elimination of the extensive vibration. The analysis is complemented by numerical investigation using Computational Fluid Dynamics methods.
