Conceptual design of bridge crane 8 tonne
Franc, Šimon ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with conceptual scheme of a bridge crane with carrying capacity of 8 tons. Intention of this thesis is to scheme out the main specifications and size of this bridge crane. First of all we design and calculate the main bridge girder. Afterwards we calculate and design the cross bars and the travelling wheels. At last the desigh of an electromotor for powering the movement of the bridge crane takes its place.

Reconstruction of the road bridge near the village Holýšov
Svoboda, Adam ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The thesis deals with design of strengthening of existing bridge structure near the village Holýšov using modern method of additional presstresing. The bridge over the river of Radbuza is h-shaped beam bridge, which was built in 1924. In the present state its load capacity is under the limits for bridges situated on first-class roads. Original documentation of the bridge does not exist, the main source of information about construction details is the diagnostics research. The method of reinforcement by post-tensioning by cables in substituted cable ducts is highly efective in terms of the incerease the load capacity of existing bridge structure. The design of strengthening and the final load capacity was verified by static calculation.

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.

Design of bridge over Kyjovka river
Zlatuška, Karel ; Nečas, Radim (referee) ; Zich, Miloš (advisor)
The subject of Bachelor’s thesis is the design of the road bridge over the Kyjovka river on the Na Šlajsi street in Lanžhot. The work is focused on the detailed static analysis of the one span load bearing structure made of reinforced concrete. Two alternative versions have been designed and one of these was further assessed in the static calculation. The chosen version is a parapet girder composed of two main longitudinal members of variable section height. These girders are connected together with a deck slab which is supported by tapered cross beams. The theoretical span of the construction is 13 meters. The static model is created and solved in software Scia Engineer 2013.1 and its results are controlled manually according to the principles of basic structural mechanics and linear elasticity. Assessments are calculated by hand according to Eurocode. In the calculation only vertical load effects are considered.

Bridge across railway line
Kubelka, Jan ; Neudert, Zdeněk (referee) ; Panáček, Josef (advisor)
The final thesis is focused on design of road bridge over a railway track. The design is processed in tree options - a cast-in-place concrete structure, brigde as a haunched beam and a prefabricated ginger bridge. The third option was chosen. To model the structure and to obtain the internal forces is used FEM computational software Scia Engineer 15.1. All calculations were performed in accordance with Eurokode.
