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.

The aim of the master thesis was a design of the steel-concrete composite road bridge for a main road in Ostrava. The part of the design was a variant design of the bridge which has theoretical spans equal to 44 m + 55 m + 44 m. Total span of the bridge is then 143 m. Two variants of the bearing steel structure are compared in the preliminary structural design, in the first one a twin-girder is designed and in the second one a box-girder bridge is assessed. The width of the bridge is 14 m and a launching of the bridge without temporary supports is chosen as the assembly method. The design of the bridge structure was carried out according to the valid standard ČSN EN. The final thesis contains variant design, structural design report, where a bill of quantities is stated, engineering report and drawings.

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.

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.

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.

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.

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.

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.

The aim of this diploma thesis is to design and assess highway bridge. The structure is located on the D1 motorway section bridging a wide valley between the Slovak villages Doľany a Klčov. Three variants have been created – box girder bridge with transverse overhangs, a pair of girder bridge and a pair of box girder bridges. The various proposals were compared with each other. For the most valuable option is selected prestressed box girder bridge with transverse overhangs, which are supported by prefabricated concrete struts. The selected proposal was subsequently elaborated in detail, the load-bearing structure is analyzed using Scia Engineer 16. In calculating the internal forces is adjusted for the effects of construction methods, even as time-dependent analysis TDA. When designing the load-bearing structure it is considered the action of permanent load, also loading from transport and temperature. The structure is assessed for serviceability and ultimate limit states according to current standards. The bridge deck is built by incremental launching method. The principle of this method consists of building the segments in a casting yard located behind the bridge abutment. Each segment is matchcast against the previous one and prestressed to the section of structure already built. The whole superstructure is then jacked forward a distance equal to the length of this segment. This process is repeated until the bridge deck is in its final position. Chosen method of construction is very fast and efficient, to the country in the valley isn´t damage during construction.
