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.

Pedestrian bridge in Hradec nad Moravicí
Janeček, Tomáš ; Horáček, Martin (referee) ; Pešek, Ondřej (advisor)
The aim of this thesis was to design and assess a footbridge over the Moravice River for pedestrians and cyclists, as the existing footbridge is in poor condition and it is narrow, so it doesn't allow convenient movement of pedestrians and cyclists. The footbridge is located in Hradec nad Moravicí and connects Žimrovická Street with the sports complex on Na Potůčku Street. First, four different variants were considered, from which the most advantageous design was selected, and it was then solved in more detail. The winning variant is a steel arch footbridge with a lower bridge deck, while the bridge deck is suspended on two rigid arches by means of tie bars. The span of the footbridge is 28 m, the span of the arch is 5.5 m, and the entire structure is made of S 235 steel except for the screws and system tie bars.

Steel Footbridge
Bartoň, Radek ; Šmak, Milan (referee) ; Bajer, Miroslav (advisor)
This diploma thesis contains a study of current composite structure of footbridge and in part II design and assessment of steel structure of footbridge for pedestrians and cyclists placed on current footbridge location. Current footbridge is located on "nábřeží Dukelských hrdinů" in Rožnov pod Radhoštěm. In part I, assessment of the current composite structure of footbridge is done, using ČSN and ČSN EN standards for adjusted static behavior of the structure. Comparison of both assessments is made and also with an original assessment from 1988. In part II, design and assessment of steel structure of footbridge placed on currents footbridge location described in part I is done.The structure was designed as two vierendeels trusses connected with cross beams, supporting concrete bridge deck. 9 variants were examined, differing with truss height and the number of verticals. Detailed design and assessment for parts of the structure is done for the chosen variant.

Mid-Span Bridge Steel Structure
Dovičic, Boris ; Štrba, Michal (referee) ; Brosch, Petr (advisor)
The diploma thesis deals with the design of the load-bearing composite steel and concrete structure of the road bridge. The structure span a railway line and a watercourse in the urban area of the district town of Blansko. The centre to centre spacing of the bridge supports is 99.8 m. The construction of the bridge is solved in three variants with the selection of the most suitable variant. Valid Czech technical standards and technical regulations for designing bridges were observed during the design and calculations.

The road bridge
Doležal, Martin ; Barnat, Jan (referee) ; Puchner, Josef (advisor)
This master' thesis deal with the desiggning of steel bearing structure of road bridge with span of 48,5m with lower bridge deck, which cross local road over the river Thaya in the town Znojmo. Three variants have been designed of arched bridge. The most economical variant was prepared in detail and wascarried out static assessment of individual elements and selected details. In detail solved variant is the bridge with free staing arches and lower bredge deck with composite crosspiece. The span of bridge is 48,5m, width of bridge is 11,5meters, free width of main trafic area 6,5m. Camber of bridge 8,0m

Design of a steel railway bridge with lower deck over the D35 motorway
Žáček, Libor ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of the thesis is the design and assessment of a steel bridge over the D35 motorway in the section Opatovec – Staré Město, on the existing railway line section 017 Česká Třebová – Dzbel. It is a single-track bridge with one span (simple beam). The bridge is designed as a main beam of welded I profile, reinforced with a truss structure (Prostas beam). The bridge deck is designed orthotropic, consisting of bridge deck plate, longitudinal and transverse reinforcements. The structure is designed with S355 steel. The theoretical span of the bridge is 37.1 m. The total length of the steel structure is 38.02 m. The transverse distance between the main girders is 5.8 m. The clear width on the bridge is 5.3 m. The height of the main girder in the middle of the span is 5.0 m. The structure is supported on four pot bearings placed on the abutments To assess the structure and determine the internal forces, a model of the structure was created in Dlubal RFEM 5.31. The bridge plate, transverse bracing and longitudinal bracing are modelled as plate elements.

Footbridge in Blansko
Urbánek, Jan ; Štrba, Michal (referee) ; Barnat, Jan (advisor)
The subject of the thesis is design and check of steel load-bearing structure of a footbridge. The footbridge spans the river Svitava in the town Blansko. The span length is 24 metres. The structural design is spatial bar structure with two main trusses. The upper and lower chords are curved in the shape of circular arch and they are connected by diagonal bars. In the level of the upper and lower chords the beams are connected by floor beam. Horizontal rigidity of the upper and lower construction area is secured by bracings. The bridge deck is laid on the lower floor beam. The solution is the result of the comparison and evaluation of two variants.

Footbridge for pedestrian and cycling traffic in Kunovice
Boček, Michal ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
Subject of this bachelor`s thesis is drafting and assessment supporting structure of footbridge for pedestrian and cycling traffic over a water flow. Footbridge is designed because of transfer of cycling path in Kunovice community, Uherské Hradiště district. Structure have two main girgers joined with lower deck. Structure is computed as space steel truss from tubes, including railing beams, with load in all direction. Margin of supporting structure is 26,550m, free width is 3,200m.
