Prestressed bridge No. 209 over the expressway R2 in Slovakia
Mareček, Tomáš ; Formánek, Ing Martin (referee) ; Koláček, Jan (advisor)
This thesis deals with a design of the bridge for second class highway S7,5 through speedway R2 in Slovakia. From the three proposed versions the version with unicameral structure was chosen for further detailed analysis. The longitudinal direction of the structure is designed as continuous three fields. The lenght of the spans is 23,1 + 33,0 + 23,1 m. Detailed design of the selected version of the structure of prestressed concrete bridge is processed according to limiting conditions, including consideration of the impact of the progressive construction of the bridge. It is elaborated a detailed structural analysis including drawings and visualization.

Highway bridge over wide wally
Mertová, Eliška ; Smejkal, Ing David (referee) ; Klusáček, Ladislav (advisor)
The aim of this diploma thesis was the design of three possible variants, how to span the wide and deep valley with a bridge. After an evaluation, situation of the highway on the only wide load-bearing structure which is constituted by a box girder with transverse cantilevers supported by prefabricated bar braces, was chosen as an optimal solving. The load- bearing structure made of post- tensioned concrete is going to be incrementally launched and be supported by one-column pillars along an axis of the motorway. The work is composed of a detailed design of this preferred variant, which is processed according to the ultimate and serviceability limit state including the construction stage analysis of the bridge by the construction technology by an incremental launching method.

Prestressed bridge on the expressway
Juřenčáková, Jana ; Zlatuška, Karel (referee) ; Koláček, Jan (advisor)
The purpose of the diploma thesis is to design a expressway bridge over the river Vsetínská Bečva. The bridge is located between Valašské Meziříčí and Vsetín. Separate superstructures are designed for each directions of the expressway. The right superstructure, which is wider, is considered for detailed design. Two variants were proposed, A double T beam superstructure and a box girder superstructure. The three span box girder superstructure was chosen for the design. Spans are 48+65+48 m long. Two options of construction process of the superstructure were proposed. This bridge is designed according to the limit states, the influence of construction process is considered. Structural models of construction were made as a finite element model and a plate model. Structural analysis, drawings and visualization were developed.

Design of a steel railway bridge with lower deck over the D35 motorway
Žáček, Libor ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of the thesis is the design and assessment of a steel bridge over the D35 motorway in the section Opatovec – Staré Město, on the existing railway line section 017 Česká Třebová – Dzbel. It is a single-track bridge with one span (simple beam). The bridge is designed as a main beam of welded I profile, reinforced with a truss structure (Prostas beam). The bridge deck is designed orthotropic, consisting of bridge deck plate, longitudinal and transverse reinforcements. The structure is designed with S355 steel. The theoretical span of the bridge is 37.1 m. The total length of the steel structure is 38.02 m. The transverse distance between the main girders is 5.8 m. The clear width on the bridge is 5.3 m. The height of the main girder in the middle of the span is 5.0 m. The structure is supported on four pot bearings placed on the abutments To assess the structure and determine the internal forces, a model of the structure was created in Dlubal RFEM 5.31. The bridge plate, transverse bracing and longitudinal bracing are modelled as plate elements.

Static and modal analysis of bridge structure
Turková, Martina ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis is based on structural analysis calculated by Dopravoprojekt Ostrava company that was used for dimensioning of the oblique bridge structure No. 433 27-3, in Popůvky, Přerov district. The beam model which is part of static calculation and is designed by Nexis 32 software, served as ground. The aim of the thesis was to construct an identical beam model, specifying boardwall model and perform static and modal analysis. All calculation were done in Dlubal RFEM 5.01 software.

Static analysis of railway bridge
Bureš, Vojtěch ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis deals with the static analysis of a railway bridge. Using AxisVM X6 software, I created 4 different models and compared them not only with each other, but also with simple manual calculations. Two models are beam models, the third is shell model, the fourth is also shell but with an end ledge that reinforces the entire structure. The structures are loaded by a manually calculated load according to the standard.
