Slab bridge
Malý, Jan ; Muroň, Vlastimil (referee) ; Panáček, Josef (advisor)
Bachelor's thesis deals with the design of a road bridge over the Volyňka river. Three bridging variants were proposed, of which the bridge variant, whose supporting structure consists of an additional pre-stressed concrete slab, was chosen for subsequent detailed assessment. The variation with prestressed prefabricated girders with composite slab is chosen for more detailed assessment. Detailed structural design is made and selected parts of the construction are checked for ultimate and serviceability limit state by Eurocode. Calculation of load is made by manual way and then by exact way with program Scia Engineer 22. The results from both calculation methods are then compared. Detailed drawings and visualization are made as well.

Pedestrian bridge in Příbor
Škrachová, Ivana ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The subject of the bachelor thesis is about a concept of pedestrian bridge across the river Lubina in city Příbor. For final design of pedestrian bridge was made three preliminary designs of constructions and one of them was choosen for detailed processing, assessment and making drawings. The choosen variant is made as prestressed concrete's beam with parapets. For calculation of internal forces was used Scia Engineer Software. Assessment was made by method of ultimate and serviceability limit state. A process of constructio's works are not going be treated in this work.

A bridge with one field over a watercourse
Pylypenko, Jevhenij ; Požár, Michal (referee) ; Strnad, Jiří (advisor)
The thesis focuses on the design of the superstructure of a new concrete bridge, which replaces an old substandard construction. The bridge should serve for passing roadway across the river Šlapanka, in village Mírovka, Kraj Vysočina. The static system of new construction is a one-span post-tensioned slab which is simple supported on edges. Span length of the superstructure is 17,5 meters. From three variants of concrete slab cross-section, a trapezoidal-shaped one was chosen. Concrete slab was assessed by the ultimate limit state and service limit state according to recent standards (Eurocode). The preliminary design of post-tension was processed according to standards (CSN).

Pedestrian bridge across the river Svitava
Bezručová, Kristína ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the river Svitava. Three variants were designed. The variant of one-span frame construction with a parabolic haunch was chosen for analysis. The calculation of load effects was made in software Scie Engineer. For evaluation was used MS Excel. The design and assessment are according to the europien standards. The time dependent analysis is not treated in this work.

Flyover crossing Hlavní street in Frýdek-Místek
Pěkník, Robin ; Klusáček,, Ladislav (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor´s thesis is the design of the flyover crossing Hlavní street in Frýdek-Místek. The main topic is static calculation of supporting construction of one span bridge. Two studies were executed and the second option with pre-stressed prefabricated beams VSTI2000 was chosen. The beams are 18 meters long and coupled with a reinforced concrete slab. Static model and effects of loadings are solved in software Scia Engineer. Reviews are calculated by hand according to Eurocode. Calculation is made without effects of creep, shrink and time analysis.

Strengthening of roof girders in production hall
Wawreczka, Karel ; Strnad, Jiří (referee) ; Klusáček, Ladislav (advisor)
The aim of my bachelor’s thesis is strengthening of girder roof construction in a production hall. The roof girders were designed 18 years ago in accordance with the Czech standards valid at that time. All the girders are now recalculated according to valid European norms. It is suggested to use prestressed cables guided along the girder construction. Because of the lack of space around the front of girders, it is designed to use prestressing from in the middle. In order to design the cable geometry and the biasing force, it was crucial to take into account shear resistance as well as constraining compressive stress in the concrete. Calculation of the effects of load is carried out by Scia Engineer 2015 computer software whereas Excel has been used for all the other calculations.

Beam bridge over a local road
Kunčarová, Edita ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The aim of this thesis is to design a one-span pre-stressed bridge structure over a local road. There are three possible versions of this particular construction designed as a part of this thesis, one of which was chosen for further design. The structure has been designed and calculated for the ultimate limit state as well as the service limit state. The calculations were made both by software and manually. Scia Engineer 19.1 has been used for software calculations and for the display of internal forces.

Design of the single span bridge in Vražné
Juřenčáková, Jana ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The subject of bachelor thesis is a design of single span bridge in Vražné. Within the scope of thesis there are three studies of bridge. Cast-in-place concrete slab super structure was found appropriate and further calculations were assessed. Length of span is 15,00 m. Internal forces were provided by SCIA Engineer and checked with manual calculation. The supporting structure was assessed for the ultimate limit state and serviceability limit state. Calculations were made according to valid standards and regulations.
