Stress and deformation analysis of railway bridge over the Svratka River
Kovář, Jaroslav ; Žák, Stanislav (referee) ; Fuis, Vladimír (advisor)
This thesis deals with stress and strain analysis of real truss bridge structure. This structure is modelled as plane bar system. The opening part dedicates to theory, which is further used for calculations. The calculation part dedicates to compare statically determinate and indeterminate variation of structure for load by own weight and passage of the train. Analytic calculations are numerically verified with program ANSYS. In thesis is assessed concentration of stress, when the rivet drops out of the structure. The next part of thesis dedicates the spatial model of bridge, which is compared witch plane model.

Aviation maintenace crane
Bureš, Martin ; Šťastný, Antonín (referee) ; Pokorný, Přemysl (advisor)
This master´s thesis solves design of a mobile crane for handling air aggregates and ejection seats. Handling crane provides lifting a maximum weight of 300 kg to a height of 4600 mm. Subject of the work is the choice of appropriate technical solutions, design of lifting mechanisms, supporting structures and accessories. The suitability of the solution is checked by strength analysis of individual units. Another task is to provide mobility equipment and control stability against overturning. The appendix includes protocols static analysis of the program Nexis32, drawing overall crane assembly and manufacturing drawings selected parts.

Design of truss jib offshore crane
Palatinus, Peter ; Horák, Michal (referee) ; Pokorný, Přemysl (advisor)
This master`s thesis deals with the design of an offshore crane jib with maximal safe working load 80 tons and maximal radius 45 meters. The design consists of a design solution of the steel construction and a stress analysis of its FEM model, which was performed using NX I-deas software according to the requirements and specifications of the Huisman company. This thesis includes source materials for drawing documentation.

Bridge crossing over Svitava river and railway track in Blansko
Smělíková, Petra ; Konečný, Vojtěch (referee) ; Křižan, Lukáš (advisor)
The aim of the Diploma Thesis is elaboration of study of bridge crossing over the Svitava river and ČD railway track in Blansko. It concerns a five-pole steel beam road bridge with through-span which carries road of the third category. The static system of the construction is solved as solid-web beam of 1.3 meters height which is in three middle spans reinforced by truss construction with top chord and system of diagonals without verticals. The height of the main beam where reinforced by trusswork is 4.75 meters. The width of spans in the road axis is 18.5 + 30.525 + 44.4 + 30.525 + 18,5 metres. The bridge deck consists of steel cross beams bonded with reinforced concrete slab of 200 millimeters of thickness. The drive-through width of the roadway is 7.0 meters. The bridge is fitted with right-sided walkway placed on steel cantilevers. The walk-through width of the walkway is 3.0 meters. Material used is S355 Steel, C30/37 Concrete and S460 Steel which is used for marginal spans of the bridge. Load-bearing construction is assessed in compliance with current technical requirements laid down by European Directives, so called “Eurocodes”. The calculation of inner powers is performed using the Scia Engineer 2013.1 software.

Timber structure of a view tower in southeast Moravia
Vrbka, Jan ; Straka, Bohumil (referee) ; Šmak, Milan (advisor)
he master’s thesis consists of a case study of an observation tower design made of glue laminated timber and steel. There are two different tower shapes of anchored or free standing tower and these towers are compared. One of the design is chosen and elaborated into final detailing. A short review of main issues bound with the observation towers is given. The review deals mainly with loading (mainly priniples wind loads are analised) and evaluating of towers (ultimate limit states, service limit states and acceleration comfort). The height of final construction is up to 60m. The design is formed by a space lattice structure made of glue laminated timber and steel members of different class. The members are fastened mainly by means of dowel joints with slotted-in-plates . There is a light steel stairway inserted into the main structure.

Behavior studies of the timber footbridges structures
Vitásková, Petra ; Brdečko, Luděk (referee) ; Zídek, Rostislav (advisor)
Master’s thesis „Behavioral studies of the timber footbridges structures“ deals with static models of timber footbridges. This thesis mainly consists of the behavioral study of historical timber footbridge in the village of Černvír in Vysočina. Based on the actual design of the bridge a three-dimensional beam model was created. This thesis also includes two contemporary alternatives of timber covered bridges. The individual structural elements were assessed according to the applicable standards. To analyze the model FEM program SCIA Engineer 2012 was used.

Static and dynamic assessment of an outlook tower construction
Valíček, Jan ; Kala, Jiří (referee) ; Salajka, Vlastislav (advisor)
This thesis deals with static and dynamic analysis of an lookout tower construction. For dynamic analysis a computational model in ANSYS software is created. Static analysis is performed by Scia Engineer software. Both of this software use finite element method. It is also focused on wind load determination by Eurocode 1, structural factor calculation, modal analysis and vortex shedding. Verification of selected parts according to Eurocodes is included.

The two-track railway bridge
Loučka, Miroslav ; Karmazínová, Marcela (referee) ; Puchner, Josef (advisor)
Master´s thesis describes the design of the railway bridge in Ústí nad Labem. Length of the structure is 200.00 meters, the height of the structure is 32.61 m and width of the structure is 12.10 m. Main structural system is composed of a spatial strut-frame structures. The bridge carries an important railway stations between Usti nad Labem Západ, Usti nad Labem Střekov. Part of the proposal is a footbridge for pedestrians.

Roof structure of sport stadium
Pijáčková, Jana ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The subject of this thesis was to develop a conversion and a variant of the existing steel structure roofing ice rink in Třinec. The building has a rectangular plan on pages 90 m x 60 m, minimum headroom inside the building is given with regard to the requirements of operation. The roof structure is stored in steel and concrete columns around the perimeter at a distance of 7.5 m. Variant solution for the design of new steel roof structure was chosen arc grate. The design consists of 13 main arc lattice girders in the transverse direction for a distance of 7.5 m in the longitudinal direction of the structure consisting of planar lattice strips (girders) and purlins. All this is complemented by a reinforced system. Two dimensions are retained.
