The reconstruction of the prestressed railway bridge
Macková, Lucie ; Šedivý, Jan (referee) ; Klusáček, Ladislav (advisor)
Diploma thesis describes the design of main structure reinforcement of the railway bridge ,,Gagarin’’ in the 5,872 km of route Český Těšín – Ostrava Kunčice. Reinforcement is achieved by combination of composite slab-shaped channel with the continuous gravel ballast and free additional prestressing cables. There are 3 variants for which the design and assessment of main structure is performed. Evaluation of the options is performed on basis of calculations. There are made additional calculations and drawings for best variant.

Road bridge in the village Ždár nad Sázavou
Pylypenko, Jevhenij ; Šiška, Radek (referee) ; Strnad, Jiří (advisor)
The final thesis is focused on design of the superstructure of a new concrete bridge in city Žďár nad Sázavou, Kraj Vysočina. The bridge should serve for passing roadway, cycle path and pavement across the river Sázava. The base for bridge design include the measured terrain. The static system is self-anchored system of arch, braces and prestressed semi-through deck. The bridge span is 74,02. Arch span is 57,00 m with high 12,00 m. Construction was assessed by the ultimate limit state and service limit state according to recent standards (Eurocode).

Analysis of a joint of steel tubes members and its practical use in load-bearing structure of a pedestrian bridge
Kuttelwascherová, Olga ; Balázs, Ivan (referee) ; Pešek, Ondřej (advisor)
This master‘s thesis deals with the analysis of the behaviour of the joint and its subsequent use in the supporting steel structure of the pedestrian bridge. The detail in question may find application as a structural solution for the crossing of closed cross-sections. The analysis of the joint consists of experimental analysis, numerical analysis and parametric study. Furthermore, the structural design of the pedestrian bridge was carried out. The pedestrian bridge is located in the grounds of a primary school in Litomyšl. It enables the connection of two existing buildings. In the design of the pedestrian bridge, the detail in question is used at the crossing point of the bracings. All steel elements are designed in S355 structural steel. In addition, wooden elements for the walking surface are designed in C30 coniferous wood and glass panes acting as a curtain made of insulating glass. Dlubal RFEM was chosen for the numerical analysis, parametric study and the structural model of the pedestrian bridge.
