Design of railway arched bridge across the I/33 roadway
Uher, Michal ; Nečesal, Petr (referee) ; Marván, David (advisor)
This master thesis content is alternative design of one span single-railed steel bridge. The bridge is located in km 44,179 on the track Jaroměř - Dvůr Králové. Crossing barrier is roadway I/33. The teoretical distance between supports is 42 m. Main bearing structure is designed as Langer beam. Structure consist of beams, arcs, suspenders, bridge deck with longitudinal and transversal bracings. Elements of the structure are made out of steel S355J2+N, S235J2+N, S355NL. The bridge is designed according to current standards ČSN EN.

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.

Rail bridge over river Váh between Nemšová and Trenčianska Teplá
Lezová, Lívia ; Horáček, Martin (referee) ; Pešek, Ondřej (advisor)
The diploma thesis is focused on the design of a new steel structure of a single-track railway bridge with bottom bridge deck. The solved bridge construction is located on line No. 123 between Nemšová and Trenčianska Teplá at the point, where the line crosses over the river Váh. The existing bridge on the line has a span of 50 + 50 + 50 + 50 m. The assignment was processed in five variants of a steel bridge structure with a bottom orthotropic deck. Each variant has a different static system, a different number of fields and a different type of superstructure. The comparison of variants was performed using multicriterial evaluation based on selected criteria. The most suitable variant was elaborated in more detail. The calculations were performed according to valid ČSN EN standards.

Static verification and variant design of steel structure of railway bridge
Boček, Michal ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this diploma thesis is static verification steel structure of exist railway bridge in accordance with the valid standards. The bridge have three simple spans with a span of 25; 98 and 25 meters, outer fields are simple beams, the middle field is the beam reinforced with an arch with vertical rods. Steel orthotropic deck with longitudinal stiffeners and crossbeams. Further were designed and analyse other possible options super structure of the middle field, and the resulting variant as a circle span with radial rods was detail solved and made documentation.
