Design of doublebeam of bridge crane 8 tonne
Bobčík, Martin ; Pokorný, Přemysl (referee) ; Kubín, Martin (advisor)
This bachelor thesis deals with design of doublebeam of bridge crane (8 tonne). The purpose of this thesis is to design the main parameters of the crane bridge. First of all, I chose from the catalog wire rope hoist. I proposed preliminary dimensions of mainbeam and crossbeam. I made strength check of mainbeam and crossbeam. For attachment mainbeam and crossbeam I chose fitted bolts. I calculated required number of fitted bolts M12. From the standards I chose wheels. I checked the wheels to maximum contact pressure and service life. I chose bearings from catalog SKF. I checked the bearings to service life. I proposed dimension of shafts. From the rolling resistance and friction, I calculated the power output of the engine. At the last I proposed cable trolleys and control of the crane.

Timber foot bridge over a wolf run
Mynaříková, Alice ; Šmak, Milan (referee) ; Straka, Bohumil (advisor)
The subject of this diploma thesis is the construction of a timber foot bridge over the wolf run in the Šumava National Park. The total length of the bridge is 240 m with two ground plan bends. The foot bridge includes three viewing decks, two of which are covered with shed roofs. The foot bridge is divided into 16 segments. Each segment is 15 m long with a width of 2.2 meters. The ground plan dimensions of the viewing decks are approximately 15x7 and 15x11 m. As the main structural material has been chosen glued laminated timber of the strength class GL28h, other elements are made of solid timber of the strength class C24. The thesis includes an introductory document, options analysis, technical report, static analysis, bill of material and drawings.

Bridge crane
Plášil, František ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with the design of an overhead crane. In the first part, the research of the current situation and description of individual parts has been made. It is followed by the choice of a suitable concept design with respect to the specified parameters. The following part describes important technical calculations for the structure of the crane. Calculations are made according to valid Czech state standards. In the final part, the calculation of the structure using the finite element method analysis is performed and the financial balance of the project is proposed. Last but not least, an assembly drawing of the crane and selected detailed drawings are attached.

Static verification of steel temporary bridge ŽM 30
Tomčíková, Lucie ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The content of the bachelor thesis is static verification of a steel temporary bridge ŽM 30, the span of the first version is 18 m, the span of the second version is 30 m. The first version also contains a comparison with the results of load test performed on the temporary bridge. Steel construction is made of steel strength class S490. The calculations are made according to valid norms ČSN EN.

Bridge crane one-girder
Stanec, Stanislav ; Malach, František (referee) ; Malášek, Jiří (advisor)
This diploma thesis deals with constructional design and a calculation of one-girder bridge crane with the requested primary parametres: lifting capacity 10 000 kg, span 12 000 mm, wheel base 2 500 mm, travel height 7 000 mm. In diploma thesis, there is executed analysis of constructional designs of box girders, drawn up technical report with the analysis of the choice of the construction with important technical and physical calculations. Calculations were executed according to valid Czech state norms and literature. Drawing documentation is enclosed to this thesis.

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.

Bridge across the Morávka river at km 6.205
Hollý, Tomáš ; Marván, David (referee) ; Nečesal, Petr (advisor)
The subject of the thesis is to design and consider steel superstructure of a composite steel-concrete road bridge. It is a continuous beam with seven spans of 36,0 + 57,0 + 75,0 + 90,0 + 75,0 + 57,0 + 36,0 = 426 meters. The superstructure consists of welded I-beams, which pass into closed box girder. The calculations take into account the construction phase.

Footbridge for pedestrian and cycling traffic in Kunovice
Boček, Michal ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
Subject of this bachelor`s thesis is drafting and assessment supporting structure of footbridge for pedestrian and cycling traffic over a water flow. Footbridge is designed because of transfer of cycling path in Kunovice community, Uherské Hradiště district. Structure have two main girgers joined with lower deck. Structure is computed as space steel truss from tubes, including railing beams, with load in all direction. Margin of supporting structure is 26,550m, free width is 3,200m.
