Bridge across the I/11 road
Macák, Jan ; Šrubař, Jiří (referee) ; Panáček, Josef (advisor)
This diploma thesis deals with a project of a road bridge. The bridge is located on a second class road S 7.5/50 and goes over a I/11 road and a local road crossing in Bystřice. Three options of the road bridge are conceived out of which the connected beam girder is chosen for further development. A calculation of the structural stability of the load-bearing construction, that includes time analysis of the construction work (i.e. particular phases of the construction), is added to the project. The structural stability calculation is assessed in accordance with valid European standards. Drawing documentation, a time schedule and 3D visualization of the road bridge is also attached to the diploma thesis.

Prestressed bridge No. 209 over the expressway R2 in Slovakia
Mareček, Tomáš ; Formánek, Ing Martin (referee) ; Koláček, Jan (advisor)
This thesis deals with a design of the bridge for second class highway S7,5 through speedway R2 in Slovakia. From the three proposed versions the version with unicameral structure was chosen for further detailed analysis. The longitudinal direction of the structure is designed as continuous three fields. The lenght of the spans is 23,1 + 33,0 + 23,1 m. Detailed design of the selected version of the structure of prestressed concrete bridge is processed according to limiting conditions, including consideration of the impact of the progressive construction of the bridge. It is elaborated a detailed structural analysis including drawings and visualization.

Bridge over a highway
Vaculíková, Klára ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The diploma thesis describes the design of curved, pre-stressed concrete bridge over the highway D1. A variant, that is chosen for detail analysis, is a spine girder construction as a continuous beam with 3 spans. The thesis solves the construction to limit states according to applicable European standards (Eurocodes). There are developed clear and detailed drawings and visualization of the bridge.

Bridge over the Kyselá voda brook valley
Svoboda, Tomáš ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
The subject of the diploma thesis is the design of the ghrinder bridge over the Kyselá voda brook valley. The main topic is static calculation of supporting construction of six span structure. Two studies were executed and the second option, pre-stressed girder bridge was chosen. The lenght of the spans is 27 + 6 x 35 + 27 m. Static model and effect of loading are solved in software Scia Engineer. Reviews are calculated by hand according to current standards.

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 across Bystrica creek
Nani, Pavel ; Glovina, Filip (referee) ; Zich, Miloš (advisor)
The subject of my diploma thesis is a detailed static calculation of the post-tensioned concrete road bridge across Bystrica creek near Banska Bystrica in Slovakia. The bridge is element of turning ramp a motorway R1. The spatial curvature continuous bridge has 9 fields. It was made a spatial curvature computational model of the bridge for a structural analysis. The model was comparison with a straight computational model of the bridge. It is made comparison effect of the construction bridge in stages on the size of the internal forces too. The load-bearing structure was checked according to CSN EN 1992-1-1, CSN EN 1992-2 and CSN 73 6214.

Bridge on a ramp in Brno
Vančura, Lukáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The topic of the thesis is the design and assessment of roadway bridge structure, which is curved in the horizontal plan with a very small radius. Bridges is part of the flyover crossing in Brno. There are designed two variations of which are further developed the variant of the two-chamber cross-section. Calculations and assessments are conducted in according to the valid European standards (Eurocodes). The static calculation is supplemented with a clear technical drawings and visualizations.

Simulation and statically analysis of cieling structure by Ansys FEM program.
Obršlík, Petr ; Keršner, Zbyněk (referee) ; Křiváková, Jarmila (advisor)
This thesis mainly deals with modeling and static analysis of the ceiling structure in the basic environment of ANSYS. The first part is focused on verifying correctness of the model most stressed parts of the structure with a simple hand-static calculation by the process of stress on a continuous beam. The main part is devoted to modeling composite structure, element types, specifying loads and boundary conditions by ANSYS FEM program. In the end, there are the results of stress and deflection presented, and the structure is evaluated at the ultimate limit state and serviceability limit state.

Highway bridge ower the II/464 road
Zalubel, Tomáš ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
The master´s thesis is about detailed design of highway bridge from prestressed concrete between the cities Brno and Ostrava. The construction is continuous and consists from three fields. Internal forces was taken from software SCIA Engineer. The static assessment was realized according to limit states. Counstruction is evaluated according to the current standards.

Bridge across the Lochkov Valley
Zvolánek, Lukáš ; Juchelková, Pavlína (referee) ; Stráský, Jiří (advisor)
The theme of the Master’s thesis is detailed design of superstructure for selected option of the bridge. The bridge carries highway across Lochkov valley. The superstructure, 6 spans, is made of one cell continuous box beam with large overhangs supported by prefabricated struts. The continuous beam is in plan curvature. As the first, side spans 1, 5, 6 will be casting on fixed scaffolding. Spans 2 and 4 will be casting using cantilever method, gradually hanging superstructure up. For the casting the main span will also be using cantilever method, gradually removing temporary hangers of adjacent spans. The structure was analysed according to limit states. The thesis also includes a time dependent analysis of the structure and solution of influence construction on its design.
