Girder bridge over the Lužnice River
Vaculíková, Klára ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor thesis is the design of the bridge across the river Lužnice. The main topic is the design and calculation of the supporting single-span bridge construction. Three options were developed, the beam constructions and the variant of prestressed prefabricate beams. There was chosen the first option. The structure is post-tensioned. The static model and analysis of the structure has been performed using Scia Engineer 2012.0. Simplified calculations has been done by hand according to Eurocode. The calculation is made without the influence of creep, shrink and time analysis.

Slab bridge over the Lužnice River
Bárta, Vojtěch ; Zich, Miloš (referee) ; Panáček, Josef (advisor)
The goal of this bachelor´s thesis is to design a slab bridge over the Lužnice river. The bridge consists of a one span. Implementation was designed in three studies, of which is developed in detail the study of prestressed monolithic slab. To create a static model and to calculate the internal forces is used Scia Engineer 2012. The assessment is processed manually according to European standards. Losses of preload are estimated, the effect of shrinkage and creep is neglected.

Girder bridge over the Lomnice River
Svoboda, Tomáš ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
The subject of the Bachelor´s thesis is the design of the ghrinder bridge over the Lomnice river. The main topic is static calculation of supporting construction of one span bridge. Two studies were executed and the second option, pre-stressed girder bridge was chosen. The supporting construction is 22 meters long. Static model and effects of loadings are solved the in software Scia Engineer. Reviews are calculated by hand according to current standards.

Slab concrete bridge
Macák, Jan ; Suza, Dominik (referee) ; Panáček, Josef (advisor)
This bachelor thesis is dealing with a design of a road bridge. This object is located on the 1st class road I/39 and is leading over the watercourse Polecnice. Crossbreeding of the road and watercourse is located on the 22,783 km above mentioned road. I have developed 3 variants. First variant is a slab from post-tensioned concrete with a height 0,85 m. Second variant consists of precast concrete beams DS - PP1 40/85 coupled with reinforced concrete slab with a minimum thickness 0,2 m. Third variant is again slab from post-tensioned concrete but with a sloping headboard.

Prestressed bridge in Velké Pavlovice
Stloukal, Radim ; Růžička, Stanislav (referee) ; Koláček, Jan (advisor)
The subject of this thesis is to design a bridge construction over the river Trkmanka in the municipality Velké Pavlovice. The superstructure is designed as a prestressed one field slab bridge with the length of 16,85m. As a part of this thesis there is enclosed structural analysis calculated accordingly to ČSN EN 1992-1-1. The load effects were calculated by Scia Engineer and compared with manual calculation. The rest of the calculations are done manually and ocassionally compared to engineering software. The construction has been analysed for the ultimate limit state, serviceability limit state and the stress anchors have been designed.

Railway bridge over a local brook
Libiger, Martin ; Trenz, Jan (referee) ; Nečas, Radim (advisor)
The purpose of this work was to design a bridge local stream to convert single-track railway line. The possible variation deals with the construction of prestressed girder bridge on one field with the lower deck. The aim of this work was to design and evaluate the structure on the basis of ultimate limit states and serviceability limit states according to applicable EN standards.

Design of a one-span beam bridge
Fojtů, Jan ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The aim of the thesis is a safe and economical design of a bridge over a watercourse according to all valid regulations and standards. There were designed three possible options in accordance with the recommended dimensions. The variation with the cross-section that consists of two beams and effective width of flanges is preferred. The thesis is mainly focused on the design of bearing concrete structure.

Pedestrian bridge across the river Svratka
Hlava, Martin ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The subject of the bachelor thesis is about a concept of pedestrian bridge across the river Svratka. The work includes a statical calculation of the pedestrian bridge construction of one ground, which has been chosen from three other options. This chosen alternative is formed by a prestressed concrete´s plank with parapet´s supports of a variable cut earned by outer switchable cables. The calculation of the stress influence has been made by Scia Engineer Software. The construction recognition has been accomplished manually. A process of construction´s works are not going to be treated in this work.

Reconstruction of a beam bridge
Otevřel, Rostislav ; Klusáček,, Ladislav (referee) ; Nečas, Radim (advisor)
The work deals with the calculation of current carrying capacity of the bridge girder structure according to ČSN 73 6222 and the proposal for a new bridge. The bridge is used to transfer local roads across the river Svratka. The bridge is designed as a plate full cross-section, simply placed with a length of 13,174 m. The communication category is S 7.5. Loads and assessment are done according to Eurocode.
