Highway box girder bridge
Ondrůšková, Kamila ; Nováček, Jan (referee) ; Zich, Miloš (advisor)
The subject of the diploma thesis is the bridging design of the valley and Doľanský potok on the D1 motorway in the section Jánovce - Jablonov in Slovakia. Three variants of bridging have been designed and then compared. A post-tensioned construction of the box girder cross section was chosen as the most suitable variant, which was further checked. The static calculation was drawn up according to European standards.

Design of prestressed box gireder bridge
Hofírek, Radovan ; Jurík, Michal (referee) ; Zich, Miloš (advisor)
This thesis deals with bridging of a lowland valley and the creek Dolanský in the section Jánovce – Jablonov on the Slovak motorway D1. Four variants of the bridge have been developed. Subsequently prestressed single box gilder with large overhangs that are supported by precast struts was selected as the most suitable variant. The construction of the bridge will take place in a formwork suspended on overhead launching scaffolding. The static assessment according to the Europan standard has been drawn up for this variant. The load of the bridge is projected according to the ČSN EN 1991-2 - Traffic loads on bridges and the dimensoin of concrete structures according to the ČSN EN 1992-2 - Concrete bridges - Design and detailing rules. The calculation of load is done using computer software SCIA Engineer 10.1 and Midas Civil.

D3 motorway bridge at km 33,588 in Slovakia
Lipovský, Václav ; Řeřucha, Kamil (referee) ; Koláček, Jan (advisor)
The diploma thesis deals with the design of a motorway bridge carrying the D3 motorway over a deep valley between Svrčinovec and Skalité. Three variants were developed for this work, from which the variant of a prestressed box girder bridge with sloping walls was selected for a detailed solution. The main superstructure was designed as a continuous structure with five spans of post-tensioned concrete. The superstructure is concreted in phases by means of an movable scaffolding system. The total length of the supporting structure is 255.50 m. The bridge is straight in plan. The analysis of the structure was carried out by means of several models that were created in Scia Engineer 21.1. The assessments of ultimate limit state and serviceability limit state were made according to valid standarts. The analysis of the structure was carried out in longitudinal and transverse directions. This thesis also includes a time dependent analysis (TDA) that takes the construciton phases into account. Finally, drawings and visualizations were produced.

Bridge ower the Opavice river
Tang, Minh Phú ; Russnák, Adam (referee) ; Panáček, Josef (advisor)
The diploma thesis deals with the design of a road bridge on the I/57 expressway over the relocation of the cycle path, the Opavice river and the local road, which involves the relocation of the access to the waterworks. The bridge structure is located in the territory of the town of Krnov. A study of the area's bridges is part of the project and three studies have been prepared. Study A was chosen for detailed processing. It is a continuous box girder bridge with three spans. The superstructure is designed as a monolithic, post-tensioned structure. A sliding girder is being investigated for the structure's construction. Scia Engineer 18.1 is used to do the load effects computation. Only the consequences of vertical load effects have been addressed, with no consideration of horizontal load effects. The structure was evaluated using limit states, taking into account the impact of construction on its design.

Bridge formed by cell box girder
Zifčák, Karel ; Brtáň, Stanislav (referee) ; Nečas, Radim (advisor)
The subject of this thesis is the design and assessment of the bridge construction across the deep valley on highway traffic. From three variants, which were compared to each other, was the most suitable further examined. The solved structure is made of post-tensioned concrete, and is formed with cell box girder with transverse overhangs, which are supported by prefabricated struts over the length of the bridge. The load was considered by the European Standard EN 1991-2 - Traffic loads on bridges and dimensioning according to EN 1992-2-Design of concrete structures - Concrete bridges - Design and detailing rules.

Highway viaduct
Zatloukal, Bohuslav ; Šopík,, Leonard (referee) ; Stráský, Jiří (advisor)
The subject of this thesis is the design and assessment of the bridge across the expressway and the deep valley in section Hričovské Podhradie - Lietavská Lúčka of highway D1 in Slovakia. The box girder structure with eleven spans was chosen of three variants. For each course there is a separate structure. The design of the bridge is carried out according to limit states including consideration of the impact of construction. The assessment of the construction is carried out using the beam model. The appendix contains structural analysis, drawings and visualization of the bridge.

Bridge formed by cell box girder across the expressway
Klein, Vojtěch ; Volák, Ondřej (referee) ; Nečas, Radim (advisor)
The aim of this thesis is to design a bridge over an expressway and a railway. There have been designed three alternatives. For detailed solving was chosen variant transferring directionally divided communication by two identical bridges, formed by a cell box girder. The thesis includes drawings, representation of the construction process, visualisations and a structural analysis. Designing and checks were carried out according to European standarts.

Multi-span highway bridge
Doležal, Lukáš ; Novák, Richard (referee) ; Koláček, Jan (advisor)
The subject of diploma thesis is designing multi-span highway bridge over Řepovský potok valley, dirt roads and biocorridor. Three variants of bridge were designed and one of them – box girder 10 span bridge, has been chosen. Bridge deck is made from cast in place post tension prestressed beam. Load-bearing structure is concreting step by step on fixed and moving support. Total length of bridge is 560 m. The analysis of structure was projected on several computational models. They have been made in software Midas Civil and SCIA Engineer 18.1. The assessments of ultimate limit state and serviceability limit state were made in all steps of building in longitudinal and cross direction. In the analysis in longitudinal direction is included the time dependent analysis. Structural design was made in software MS Excel according to valid standards. Finally, drawing documentation and visualization were made.

Flyover bridge over the Bečva river
Pidima, Jan ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The thesis deals with a design of a highway bridge with multiple spans. The bridge is constructed for highway D1 and goes across the river Bečva close to the city Přerov. Two different solutions were carried out from which a solution with subsequently prestressed box girder was chosen. Static model and load actions were modelled in program Scia Engineer 2016.0. Design checks were done manually according to corresponding Eurocodes. Load actions from wind, uneven support settling and horizontal actions from transit were neglecte.

Bridge ower railway line
Prekop, Michal ; Russnák, Adam (referee) ; Panáček, Josef (advisor)
Diploma thesis is focused on a design of the road bridge of the category S7,5 in cadastral territory of a municipality Polanka nad Odrou. Three preliminary studies have been proposed. Box girder beam with a slant walls were selected for more detailed processing. Construction of the bridge is going to be build by time-dependent analysis on a solid formwork. The calculation of load is done by using computer software Midas Civil 19 v 2.1. and Scia Engineer 19.1. Selected preliminary was assessed according to the recent Europan standards.
