The aim of this work is design and assessment of the box-girder road bridge on by-road of Bludov. Bridge is designed as composite steel concrete bridge with 5 spans with distances between supports of 31,25 m; 40,0 m; 60,0 m; 60,0 m and 40,35 m. Main bearing structure is designed as open steel box-girder with reinforced concrete deck. Box girder is braced with longitudinal and transversal bracings. Main structure is separated for each traffic direction. The bridge crosses river Morava and railway in 2nd and 3rd span, respectively. The category of road I/44 is S 21,5/100. The height of steel box girder is designed as 2,5 m. Bridge will be built by incremental launching method, with in-situ casted concrete deck afterwards. The bridge is designed according to current standards. Supporting elements are designed from steel of class S 355 and concrete of class C35/45.

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 subject of this diploma thesis is the design of post-tensioned road bridge over the valley. Two preliminary studies have been proposed and one of them was selected for more detailed processing. The selected variant is a box girder with a constant height 2,5 m. The construction id divided into five span and its total lenght is 240 m Span length of construction is 18,0 m. The construction was assessed for ultimate and serviceability limit state acording to standarts and regulation. Drawings and vizualizations ard parts of the diploma thesis.

This diploma thesis deals with the proposal of a single box girder bridge of three spans in the town Blansko. It bridges the river Svitava and the main railway Praha - Brno. The calculations were carried out by hand, the model was created in the Scia Engineer programme. The thesis also describes the solving of a complicated phased construction with the necessity of turning the bridge into the final position. The construction is considered by Eurocodes.

The subject of this bachelo r’s thesis is the design a new supporting bridge construction in Prešovský kraj, district Levoča the territory of Slovak Republic. This object is located on the highway D 26,5/120, at kilometer 13,499 795 and communication of third class – 131-00 bridges. The objective is the design of a perpendicular four-span construction, which is proposed in three variants. The first variant is a chamber girder with inclined walls from post-tensioned concrete height 2,480 m. The second variant is composed of two beamed cross-section and the third variant is composed of one beamed cross-section. For detailed assessment the first variant was chosen with a length of bridging of 166,000 m. The calculation of load effects is done by software Scia Engineer and compared with a manual calculation according to current standards. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

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 diploma thesis is the design and the assessment of post-tensioned bridge structure over deep wally, which transfer road D26,5/100 on D1 in Slovakia between Hubová – Ivachnová. Three variants were designed and compared. The most suitable variant of two identical bridges with box cross-section and constant height was further assess in detail.

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.
