The footbridge for pedestrians and cyclists
Pupík, Antonín ; Sýkora, Karel (referee) ; Puchner, Josef (advisor)
This thesis deals with the design and assessment of footbridge for pedestrians and cyclists in the city of Hranice, Rybare district. The footbridge will serve as a crossing point over the river Bečva and will conect cycling trail with the street Rybarska. The content of this paper is to propose two different variants of structures. One of these options is selected based on their economic evaluation and further processed. Length of the bridge is 50m.

Ice Hockey Stadium
Čech, Martin ; Barnat, Jan (referee) ; Pilgr, Milan (advisor)
Work deals with variant design of steel structure of ice hockey stadium located in Opava. It is a three-aisled hall with shape consists of intersection of ellipse and rectangle with dimensions 70 x 82m. The roof has cylindrical shape with approx. 50 m radius. The building is about 14 m high. Object is divided to three parts – main aisle and two side aisles. The main aisle contains of a rectangle of dimensions 40 x 42 m and two semicircles of radius approx. 20 m. Frames of main aisle are made of arc roof truss connected to steel plate columns. The side aisles with rectangular shape with dimensions 15 x 42 m are connected to main aisle. The structure of side aisle is made of a sloped roof truss. Longitudinal bracing and cross bracing are used to obtain spatial rigidity of the structure. Roof and wall cladding is made of Kingspan sandwich panels.

Roofing of the platforms in Vyškov bus station
Kalivoda, Tomáš ; Horáček, Martin (referee) ; Pešek, Ondřej (advisor)
The object of bachelor´s thesis is the design and static assessment of the new roofing of the platforms in Vyškov bus station. The design is divided into two separate structures. The ground plan proportions of first structure are 54 x 7,1 m with 8 m height and the second 20 x 5,8 m with 7 m height. All dimensions are based on the nominal dimensions of the buses and their clearance heights. Steel S355, coniferous wood C14 and stainless steel 42crmo4 are used as construction materials.

Structure Design of Exhibition Pavilion
Ruček, Martin ; Šmak, Milan (referee) ; Hron, Lukáš (advisor)
Concern of my thesis is to design the main load carrying structure of an exhibiton pavilion. The pavilion itself has circle shaped footprint, 55 m in diameter. Height of the building is then 15 m. The main structure consists of planar truss elements with generally curved upper and lower chords. The web of main truss element is designed as a perforated steel wall. Structural analysis and dimension design of main truss element is realised via axis model with rigid nodes, and verified on an accurate numerical model of a truss with web modelled as a perforated steel wall. Building is designed to be situated at exhibition area of Olomouc city. Design involves all the critical cross sections, and also selected mounting joints.

Steel load-bearing structure of a sport hall
Hrtoň, Vít ; Horáček, Martin (referee) ; Balázs, Ivan (advisor)
The project's purpose is to create a design of a steel load-bearing structure of a sports hall with a floor plan measuring 30 x 63 m in dimension. The structure will be used for common indoor sports and consists of main trusses with parabolic chords and piston rods. The trusses are pinned on columns. The centre to centre spacing between the trusses is 9 m. The Columns are fixed to their bases.The Rigidity of the main frame is ensured by a sway and longitudinal bracing system. All bars are rolled steel profiles and are designed according to current ČSN EN standards. All elements are made from class S 235, S 355 or S 460 steel.

Temporary bridge for pedestrian and cycling transport from high strength material
Bártů, Adam ; Pešek, Ondřej (referee) ; Simon, Pavel (advisor)
The purpose of the thesis is to suggest a span enlargement of steel Modular footbridge ML36 for pedestrian and cycling transport. The aim is to preserve as many elements of the original construction as possible. In the thesis, three variants are discussed with the detailed focus on one of them. The chosen variant is made up by elongated original footbridge ML36, which is supported by prestressed structure. From the static point of view, it is a simply supported truss. The span of the footbridge is 39-45. The main material of the structural elements is steel S355, S460 and S520.

Steel structure of tribune
Hellebrand, David ; Hron, Lukáš (referee) ; Štrba, Michal (advisor)
This master’s thesis deals with a project of steel structure of roofed stand of a sports stadium situated nearby the city of Opava. Dimensions of roofed stand are 54 m x 10,5 m and height is 15 m. Structure is devidet into 9 parts, which are 6 m long. Design of elements and inner forces are solved with program SCIA Engineer. Computational model is designed as a three-dimensional bar structure. Two variants was solved in general and more convenient with a truss girder roof is work up in details.

Steel lookout tower
Kábrt, Michal ; Melcher, Jindřich (referee) ; Karmazínová, Marcela (advisor)
The aim of the diploma thesis was to make a structural design of steel-load-carrying structure of steel lookout tower, in the grounds of domestic brewery in Humpolec. Lookout tower will be part of newly built centre for customers of the brewery. The layout and shape of the load-carrying structure of steel lookout tower follow the brewery chimney with height of 32.7 m with circular ground plan and outside diameter of 3.5 m in the heel and 2.3 m at the top. The chimney is independent of the construction of the lookout tower. The ground plan and dimensions of the lookout tower were considered taking into account the required spacing of the structure from adjacent buildings and ensuring sufficient dimensions for the required passage between the future lookout tower and the existing building of the boiler room. RFEM was used for calculation internal forces and assessment on individual structural elements, according to the valid Eurocodes.

Static provision of castle
Kulla, Lukáš ; Bažant, Zdeněk (referee) ; Strnad, Jiří (advisor)
The aim of this final thesis was static protection for castle in Miroslavské Knínice. It was necessary to explore several respects and find signs of violation. Next analyze and propose suitable assurance of individual parts. Separe into the stages of construction and to consider the proposal in terms of ensuring the resistance of materials. Finally create a detailed documentation in the range suitable for performance. Based on engineering geology and visual survey was designed horizontal bracing prestressing cables at three levels. The first level "A" consists of a closed circuit of prestressed reinforced concrete passports, supplemented by the cross and construction of prestressed reinforced concrete passports. Next level "B,C" is used to secure the top of the building. Levels “B,C” are proposed using prestressed cable in spare cable channels.

Analysis of friction welding in the automotive industry
Čurda, Jakub ; Slováček, Marek (referee) ; Kubíček, Jaroslav (advisor)
This thesis focuses on aplication of friction welding in automotive industry, namely in the production of radius rods used in axels of heavy duty commercial vehicles by the THK RYTHM AUTOMOTIVE CZECH, a.s. company, and the verifycation of preperties of the weld. The breakdown for the rod consist of all the information on the manufacturing of the components the rod consist of, as well as information on the welding process. The theoretical part of this thesis focuses on analysis of friction weding and its mechanisms, with emphasis on the evolution and application of this style of welding. Main focus of the experimental section is verification of mechanical properties of the weld, this is done using a tensile strenght test, microscopic observation and hardness mesuring. The data collected using these tests is then utilized to form a conclusion on the practical application of this method and the friction welding process.
