Bridge crossing over Svitava river and railway track in Blansko
Smělíková, Petra ; Konečný, Vojtěch (referee) ; Křižan, Lukáš (advisor)
The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.

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.

Bridge over the Olše river in Návsí
Mendroková, Magda ; Nečesal, Petr (referee) ; Marván, David (advisor)
The diploma thesis deals with design and assessment of steel arched bridge with the semi through bridge deck placed on the third-class road. This steel structure is drawn up to bridge water barrier – the river Olše in Návsí. The distance between axes lay on abutments is 48,5 meters. The bridge´s supporting structure consists of two steel arches angled towards each other and fastened to the foundation blocks. The supporting beam of the bridge deck is tied to the arch by tie-rods. The tie-rods are designed to the V-shaped system.

The road bridge
Doležal, Martin ; Barnat, Jan (referee) ; Puchner, Josef (advisor)
This master' thesis deal with the desiggning of steel bearing structure of road bridge with span of 48,5m with lower bridge deck, which cross local road over the river Thaya in the town Znojmo. Three variants have been designed of arched bridge. The most economical variant was prepared in detail and wascarried out static assessment of individual elements and selected details. In detail solved variant is the bridge with free staing arches and lower bredge deck with composite crosspiece. The span of bridge is 48,5m, width of bridge is 11,5meters, free width of main trafic area 6,5m. Camber of bridge 8,0m

Bridge across the Morávka river at km 6.205
Hollý, Tomáš ; Marván, David (referee) ; Nečesal, Petr (advisor)
The subject of the thesis is to design and consider steel superstructure of a composite steel-concrete road bridge. It is a continuous beam with seven spans of 36,0 + 57,0 + 75,0 + 90,0 + 75,0 + 57,0 + 36,0 = 426 meters. The superstructure consists of welded I-beams, which pass into closed box girder. The calculations take into account the construction phase.

Bridge on a ramp in Brno
Diviš, Dalibor ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
Thesis involves designing and analysis of horizontally curved bridge contruction with chamber-shaped profile and oblique side walls. The object is a part of fly-over crossig at VMO Brno. Calculations are according to actually valid standards ( Eurocodes ). Thesis gives a basic look at the problematics of horizontaly curved bridge construction, including solution of prestressing cables´ 3D-tracking with usage of common software.

Prestressed road bridge in Staré Město
Juříček, Lukáš ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The thesis proposes the design of main structure concrete bridge,which is transferring highway road across the river Krupá in Staré Město.It is simple span bridge with length of 14,995 m.For the next calculation were chosen post tensioned concrete trapeizodal slab.The slab is assessment on serviceability limit state and ultimate limit state according to valid European standarts.

Prestressed road bridge in Staré Město
Krč, Rostislav ; Trenz, Jan (referee) ; Koláček, Jan (advisor)
The thesis focuses on design of superstructure of concrete bridge, which passes a roadway across the river Krupa in the town of Stare Mesto. It is a simple span structure with length of 19 meters. For further elaboration, post-tensioned concrete slab with trapezoidal-shaped cross section was chosen. Assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Furthermore, a design of post-tension according to former Czech technical standards (CSN) was studied. The thesis includes technical drawings and visualization.

Road bridge over the Trkmanka river in Velké Pavlovice
Coufal, Jakub ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The subject of this thesis is the design of the bridge constructino across the river Trkmanka in Velké Pavlovice. The supporting structure consists of a reinforced concrete slab on one field. The load was calculated in Scia Engineer software and compared with a simplified method of calculation of effective width. Static calculation was continued counted manually.
