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.

Bridge crossing over Svitava river and railway track in Blansko
Smělíková, Petra ; Konečný, Vojtěch (referee) ; Křižan, Lukáš (advisor)
The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.
