Pedestrian Footbridge across River
Sotáková, Miroslava ; Balázs, Ivan (referee) ; Brosch, Petr (advisor)
The purpose of this thesis is the design of a load-bearing steel structure of a pedestrian footbridge across the river Opava. Two variants were taken into consideration - steel tied-arc footbridge and truss footbridge. Tied-arc variant with orthotropic deck was found the most suitable for detailed proposal. The span of the footbridge is 65,00 m and height of the structure is 7 m.

Pedestrian footbridge
Bílek, Radim ; Štrba, Michal (referee) ; Brosch, Petr (advisor)
The subject of this diploma’s thesis is design of the footbridge over Radlická street in Prague. Total length of the footbridge is about 90 m. Three variant designs were made with different systems of static construction. Based on the multi-criteria analysis, the most suitable variant was chosen. The variant A, a continuous truss beam, was chosen for detailed design. It is a truss footbridge with a lower orthotropic deck without a wind bracing. The stability of the upper chord is secured by frame stiffness of verticals and stiffness of the floor beam. Detailed static calculation includes assessment of load-bearing parts of the structure and assessment of welds. The structure is made of steel class S335. Assessment and dimensioning were designed according to valid standards ČSN EN 1990-1993.

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.

Influence Selecting the Type of the Bridge Structure at km 332,420 of Railway Dětmarovice-Český Těšín by the Effects of Undermining
Chaloupka, Martin ; Puchner,, Josef (referee) ; Kmošek, David (advisor)
The aim of the master’s thesis was t odevelop alternative solutions supporting steel structure of the railway bridge on the undermined area. The range of single fields were chosen based on the location of existing substructures. Reducing the width of bridge openings were not allowed. Based on the geodetic survey plans were drawn up clear of the current state. On the basis of specifications for developing a detailed process was chosen variant Gerber’s beam reinforced with an arch in mean field. For this variant was performed structural analysis of the main parts of the main structure of the bridge, which was calculated with the effects of undermining. For variant Gerber’s beam were made clear drawings and drawing details of the selected steel bridge construction (new state). Further, detailed analysis of selected structural detail was made. Specifically, connecting rod to the main beam, which was designed optimal shape and thickness of the joints plate with a suitable radius of the firing to avoid plastification of the material in this area. Variant of the continuous beam without joints was prepared to. It has been observed, what is the effect of undermining on the stress in the construction of the bridge - was confronted with the effects on Gerber’s beam. To reduce stress in the construction of the bridge and compliance of ultimate state of applicability of the main beam has been designed bearing adjustment and after considering several options its implementation too. The economic comparison between the two variants was conducted. The assembling procedure was designed for both types of bridge structures. In the technical report we can read about due to the intention of building a new bridge and further we can find there other important technical information. In conclusion of the master’s thesis there has been recommended for the construction specific variant – from the perspective of an investor, and from the static aspect-view of the designer.

Steel Footbridge
Janíková, Dita ; Barnat, Jan (referee) ; Bajer, Miroslav (advisor)
The diploma thesis is focused on a design and appraisal of a steel load bearing construction of footbridge. The footbridge builds a new bridge across the river Ostravice in Sviadnov at Frýdek-Místek. The main subject of the diploma thesis was preparation of three variants for the footbridge. All variants were evaluated and the best one was elaborated in depth. It is a footbridge with a total span of 57 metres with a load bearing construction created two arches bent down to each orther. There is an orthotropic bridge deck with main outer lenghthways girders on the arches.

Road bridge on road III/0462 over highway D46
Vystavěl, Vojtěch ; Balázs, Ivan (referee) ; Pešek, Ondřej (advisor)
This thesis deals with design of III/0462 road overpass over D46 highway near Brodek u Prostějova. There are 2 preliminary variants. First variant is a right bridge, whose main beams are tied archs. Second variant is a skew bridge with truss superstructure. In case of second variant there are three subvariants differing with truss design. Design and calculation is done according to valid standarts and other regulations for designing bridges.

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.

The footbridge for pedestrians and cyclists
Pupík, Antonín ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
This thesis deals with the design and assessment of footbridge for pedestrians and cyclists in the city of Hranice, Rybare district. The footbridge will serve as a crossing point over the river Bečva and will conect cycling trail with the street Rybarska. The content of this paper is to propose two different variants of structures. One of these options is selected based on their economic evaluation and further processed. Length of the bridge is 50m.

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.
