Stress and deformation analysis of railway bridge over the Svratka River
Kovář, Jaroslav ; Žák, Stanislav (referee) ; Fuis, Vladimír (advisor)
This thesis deals with stress and strain analysis of real truss bridge structure. This structure is modelled as plane bar system. The opening part dedicates to theory, which is further used for calculations. The calculation part dedicates to compare statically determinate and indeterminate variation of structure for load by own weight and passage of the train. Analytic calculations are numerically verified with program ANSYS. In thesis is assessed concentration of stress, when the rivet drops out of the structure. The next part of thesis dedicates the spatial model of bridge, which is compared witch plane model.

Track Bridge Interaction
Kapounek, Jan ; Kubelka, Jan (referee) ; Plášek, Otto (advisor)
This thesis focuses on the analysis of different approaches to the evaluation of the combined response of bridge structure and continuous welded rail on 5 planned bridges on high-speed railway in the Czech Republic in the stage of Land Use Permission. The output of the analysis of these bridges is the indication and description of problematic points occurring in the methodology as well as the development of recommended steps for the calculation of the combined response of structure and track to variable actions by the method of Complex Analysis for bridges on high-speed lines in the Czech Republic. Based on this recommended procedure, a simple bridge model is created.

Railway Bridge on the Track...
Kováčová, Zuzana ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of the diploma thesis is the design and check of the supporting structure of the railway bridge on the line Brno - Česká Třebová. The bridge carries a double-track railway line across Šámalova Street in Brno. The span of the bridge is 16.58 m, the length of the supporting structure is 17.1 m and the width in cross section is 17.81 m. Two variants of the supporting structure have been developed. The first variant is a bridge with a composite supporting structure, the second variant is a bridge with concreted steel girders. A technical report and drawing documentation are prepared for the selected variant.

Railway bridge across the river Svitava
Findura, David ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
This thesis deals with a design of an one-track railway bridge over the river Svitava. Out of three proposed variants was chosen as the most economical and feasible the variant number 2 - two-beam prestressed bridge with one span. According to actual EN standards the construction was designed and assessed to the serviceability limit state and the ultimate limit state.

Napjatostně deformační analýza mostu ve Starém Městě u Frýdku-Místku
Janík, Rostislav ; Profant, Tomáš (referee) ; Fuis, Vladimír (advisor)
The bachelor thesis analyses stress and strain of real railway bridge. Construction of bridge is modelled as plane bar system. The fisrt part of the thesis deals with a research, which includes obtaining information from theory, which is necessary for the right solution of the task. Next part dedicates to analytic solution of statically determinate and indeterminate variation of structure for load by own weight and also for load during passage of the train. In the next part are the results of analytic solution verified by numerical solution in program ANSYS. In the last part is evaluated the risk of buckling for all variations of the load.

Steel railway bridge across a watercourse
Slezák, Jaroslav ; Pilgr, Milan (referee) ; Karmazínová, Marcela (advisor)
The aim of the thesis was to design and assess a steel railway monorail bridge over a watercourse. The bridge consists of three spans of 33 + 75 + 33 m. In the middle span, the main beam is reinforced with a 10 m arch and tie rods. The width of the bridge is 7.8 m. The axial distance of the main beams is 7.1. It is a bridge with a lower orthotropic steel deck.

Rail bridge over Morava river between Staré Město and Uherské Hradiště
Křivánek, David ; Štrba, Michal (referee) ; Pešek, Ondřej (advisor)
This diploma thesis deals with the design and assessment of a railway bridge over the Morava River between Staré Město and Uherské Hradiště on line No. 341. The existing railway bridge has a span of 20,5 + 60 + 20,5 m. Five different variants with different static systems were developed. All variants of the bridge steel structure were designed and solved with a lower orthotropic bridge deck. To select the final variant, all variants were statically assessed and compared using multicriteria analysis based on the selected criteria. The final variant was subsequently assessed in more detail according to the applicable standards.

Design of a railway frame bridge
Findura, David ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
This thesis deals with a design of a two-track railway frame bridge over a valley. Out of three proposed variants was chosen the variant number 1 - prestressed frame construction with variable beam section. According to actual EN standards the construction was designed and assessed to the serviceability limit state and the ultimate limit state.
