Motorway Viaduct
Polách, Marek ; Šopík,, Leonard (referee) ; Stráský, Jiří (advisor)
The thesis is a design of a bridge crossing the valley of the Hrabyňka creek as a part of road I/II. Firstly, three possible structures are designed and according to their advantages and disadvantages, the best of them is selected. In this case a cable stay bridge was selected. Following is a design of span lenghths, collumn heights and the cross-section. Then the loads are detremined and applied on a numeric model cretaed in software working on the basis of FEM. In continuation internal forces are calculated and their propriate combinations for service limit stay and ultimate limit state with time dependent analysis taken into account. In the end the reinforcement steel is designed for one part of the structure. Detailed drawings are also part of the thesis.

Design of cable-stayed pedestrian bridge
Uher, Lukáš ; Kulhavý,, Tomáš (referee) ; Nečas, Radim (advisor)
This diploma thesis aims to design a structure of pedestrian bridge over the Svratka river. To make a preliminary study of possible bridging, three different outlines were drafted. The cable-stayed variant was selected for further analysis. Two towers, inclined in both their longitudinal and transverse direction, support a cast-in-place post-tensioned concrete deck through stay cables anchored in the tower and the deck. After determining the desired initial state, a finite element analysis was carried out using the Ansys software. The capacity of all main load-bearing elements was checked so it meets the ULS and SLS design criteria in accordance with EN 1992 codes.

Road bridge over the Kráľová waterworks
Pastucha, Marek ; Novák, Richard (referee) ; Nečas, Radim (advisor)
The subject of the thesis is the design of a road bridge over a river. A suspended bridge was chosen from three variants. The calculation of internal forces was done in the SCIA Engineer program and the assessment was done by manual calculation, in the MS Excel program and in the IDEA Statica program. The construction was assessed for the limit state of bearing capacity and usability. The calculation was made according to valid standards.standards.

Pedestrian bridge across the highway D1 in Bohumín
Muroň, Vlastimil ; Puda, Vladimír (referee) ; Nečas, Radim (advisor)
The aim of final thesis is design and assessment of footbridge over highway D1 in Bohumín. The design is processed in two options. From these two options there is cable-stayed construction solved in greater detail. Because counstruction is in circular arch with small radius, it is necessary to contain real geometry to computational model. Model is created by beams and construction stages are included too. The construction is assessed for the ultimate and serviceability limit state according to valid standards. In the thesis is performed eigenvalue analysis and harmonic response of the construction. Detailed drawings are included too.

Footbridge across the Labe
Krč, Rostislav ; Romportl, Tomáš (referee) ; Stráský, Jiří (advisor)
The thesis focuses on design of prestressed concrete footbridge which passes pedestrian and bicycle path over the Elbe river near city of Celakovice in the Czech Republic. Three different bridge options were analyzed and for further development a cable-stayed footbridge was chosen. Its bridge deck is formed of a box girder supported by cables in its vertical axis and all cable stays are anchored into two concrete A-shaped pylons. This structure was analyzed in SCIA Engineer and assessment of serviceability limit states and ultimate limit states according to recent European standards (Eurocodes) was made. Both the global structural behavior and the local structural integrity of box cross-section were assessed as well as construction stages and cross-sections of pylons and cable stays. Assessments were performed in IDEA StatiCa combined with hand calculations. Eventually a dynamic response of structure was analyzed. Natural modes and frequencies were found and forced oscillation response was evaluated. The thesis includes technical drawings, construction process and visualization.

Motorway Viaduct
Čtvrtlík, Libor ; Kocourek,, Petr (referee) ; Stráský, Jiří (advisor)
The aim of diploma thesis was designing motorway viaduct over rowing track. From three possible options was selected one, which represents cable stayed bridge with three spans. Design procedures and assessments were pefrormed to comply with the ultimate an serviceability limit state according to valid European standards. The calculation was performed in software Midas Civil 2020. Structural assessment was done by IDEA Statica 10.1 in combination with hand-done calculation. The part of this thesis is also enclosed drawings and visualizations.

Design of the bridge in the town Blansko
Poukar, Kryštof ; Rybák, Vít (referee) ; Klusáček, Ladislav (advisor)
This diploma thesis deals with the proposal of a single box girder bridge of three spans in the town Blansko. It bridges the river Svitava and the main railway Praha - Brno. The calculations were carried out by hand, the model was created in the Scia Engineer programme. The thesis also describes the solving of a complicated phased construction with the necessity of turning the bridge into the final position. The construction is considered by Eurocodes.
