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).

Design of steel-concrete composite structure of road box girder bridge on by-road of Bludov
Kuba, Michal ; Marván, David (referee) ; Nečesal, Petr (advisor)
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.

Bridge over highway on a ramp
Tlamka, Tomáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The proposal is for new construction of a road bridge over the highway.Three options of solutions were proposed but only the option of connected girder slab beam of six fields was selected. This variant was assessed by static calculation. Static calculation is processed in accordance with European standards. Another important part of this thesis is also drawings, visualization, technical report and construction procedure.

BRIDGE ON D1 (LIETAVSKÁ LÚČKA - VIŠŇOVÉ) OVER VALLEY AT km 4.313
Hudyma, Nazar ; Dvořák, Tomáš (referee) ; Zich, Miloš (advisor)
The subject of this Master's thesis is the design of a road bridge on the D1 in the section Lietavská Lúčka - Višňové in the Žilina Region, Žilina District, Slovak Republic. The bridge is used to cross the valley in KM 4,313 and the road in KM 4,410. Three variants of bridging were proposed, but further in the work an assessment is made on one of the variants. The total length of the superstructure is 354.00 m, the theoretical total span of the structure is 352.00 m. The bridge has 4 spans and is constructed by free cantilever method .The locations of the supports were limited by unsuitable geological conditions at the construction site (active shear area in Quaternary sediments), especially in span No. 3 (span lenght 104.00 m) and span No. 4 (span lenght 75.00 m). The monolithic part of the bridge structure will be concreted by free cantilever method with the largest length of the cantilever 52.00 m. The outermost parts of fields No. 1 and No. 4 will be cast-in-place using fixed scaffolding.

Steel construction of the road bridge
Kloda, Petr ; Barnat, Jan (referee) ; Štrba, Michal (advisor)
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.

Rigid frame road bridge
Pohlídal, Jan ; Zich, Miloš (referee) ; Nečas, Radim (advisor)
The theme of this bachelor thesis is to design a road bridge across a river. The bridge is designed as a single-span frame structure. The soffit is unique by its parabolic course. The load effects were calculated using software Scia Engineer. Calculations by hand were carried out using MS Excel. Drawing documentation and visualization of the structure are also included.

Bridge structure over the valley
Hroudná, Denisa ; Kostka, Vojtěch (referee) ; Koláček, Jan (advisor)
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.

Bridge over the Olše river in Návsí
Mendroková, Magda ; Nečesal, Petr (referee) ; Marván, David (advisor)
The diploma thesis deals with design and assessment of steel arched bridge with the semi through bridge deck placed on the third-class road. This steel structure is drawn up to bridge water barrier – the river Olše in Návsí. The distance between axes lay on abutments is 48,5 meters. The bridge´s supporting structure consists of two steel arches angled towards each other and fastened to the foundation blocks. The supporting beam of the bridge deck is tied to the arch by tie-rods. The tie-rods are designed to the V-shaped system.
