Předpjatý most číslo 207 přes rychlostní komunikaci R2 na Slovensku / Prestressed bridge No. 207 over the expressway R2 in Slovakia

Ježek, Rostislav January 2015 (has links)
In the diploma thesis “ Prestressed bridge No. 207 over the expressway R2 in Slovakia” three variants of solution of bridging are developed. The aim of diploma thesis is evaluation of the proposed options and implementation of detailed design of the supporting structure selected variant. The thesis includes consideration of state of construction. Option chamber bridge with inclined walls on three fields were chosen for detailed static analysis. This post-tensioned structure is assessed in accordance with applicable European standards. The analysis of the construction is performed by Scia Engineer 2013 software system. In addition, the ceiling structure is assessed for pushing through. Drawing and visualization is a part of diploma thesis.

Optimalizace konstrukčních detailů jednoplášťových plochých střech / The Optimization of Structural Details for Flat Single-leaf Roofs

Matějka, Libor Unknown Date (has links)
This thesis deals with the optimization of structural details for flat single-leaf roofs. In the first part of the thesis, 3 groups of structural details for flat roof (flat roof parapet, gutter at flat roof without overhang of the roof cladding, intersection of the flat roof and vertical supporting structure) are characterized, classified and examined. In every group one of these structural details is designed with use of modern composite material based on secondary raw materials (still in development process). The theory describes the current issue of thermal bridges at constructions and applicable legislative documents. The next part introduces thermal engineering analysis (based on finite element method) of structures with annotated data outputs. The another main part of thesis provides with designed innovative optimization algorithm using multi-criteria decision analysis methods, which is then practically tested on the surveyed construction details. The conclusion summarizes the results and provides with improvements based on completed research.

Most přes místní potok / Bridge over a local brook

Růžička, Antonín January 2016 (has links)
Diploma thesis deals with design pre-stressed road bridge over the local brook and field road. There are designed 3 studies, from which variation trapezial point-supported pre-stressed concrete slabroad bridge with 3 spans is chosen. In the structural analysis of the bridge structure is assessed at the ultimate limit state and serviceability by European standards – Eurocodes. It is developed drawings and visualization of the bridge.

Most na dálnici D1 přes silnici a potok / Bridge on the D1 highway over a road and brook

Surovcová, Monika January 2016 (has links)
The aim of the diploma thesis is the proposal of a bridge structure in the direction of Přerov – Lipník in the cadastral territory of the Osek nad Bečvou. A bridge is used to overcome the road III/43612 in km 93,550, the stream Lubeň and a field trip. From tree alternatives is selected a post-tensioned two-beam concrete struction and assessed according to the limit states including an impact of phased construction according to the European standards. Also it is prepared a drawing documentation, an accompanying report and a visualization of the beam.

Předávací most kolesového rypadla / Forwarding bridge of bucket-wheel excavator

Zeizinger, Lukáš January 2016 (has links)
The document deals inspecting forces of the structure. The task of diploma thesis is analyze the crane load and chech up the stress of steel construction. Perform stress analysis forwarding bridge of bucket-wheel excavator by using finite element method. Further assess the consequences resulting from the design modifications. The project was carried out with cooperation with NOEN, a.s.

Estakáda přes silnici a inundační území / Flyover bridge over a road and inundation territory

Šťavík, Jakub January 2017 (has links)
Master’s thesis describes the design of a highway bridge over the road II/434 and inundation territory. There are some studies designed, from which the main structure was designed as a prestressed concrete double-girder bridge with 5 spans. Loading, design and assessment of structure is solved according to applicable standards CSN and EN. Calculate the effects of the load are carried in calculation program Scia Engineer 2015. Design and asses are carried only by the manual calculation. The thesis includes used materials, construction process, statically analysis and drawing documentation.

Lávka pro pěší v Kyjově / Footbridge in Kyjov

Maleňák, Jan January 2017 (has links)
The content of diploma thesis is design of the construction of steel footbridge for pedestrians and cyclists. The footbridge is across the railway in Kyjov. The design will be processed in two options of structure. The selected option will be developed in greater detail. The span of footbridge is 35 m and the width is 3 m. The contruction is made by two arched beams which are connected to the bridge deck by suspenders. The stability of the construction is provided by longitudinal bracing under the bridge deck and the bracing between the arched beams. The assessment of the structure was made according to valid standards.

Most u obce Staré Hobzí / Bridge at Staré Hobzí village

Škůrek, Ladislav January 2017 (has links)
Diploma thesis is focused on design of the road bridge across the river Moravská Dyje, close the village Stare Hobzí. The are designed 3 studies of the bridge, of wich the trapezoidal slabroad with pitches is chosen for further development. Slabroad is assessed at ultimate limit state and serviceability by the valid standarts. Calculation of internal forces is made by computer program Scia Engineer 16.0.

Spojitá betonová mostní konstrukce na rychlostní komunikaci R2 / Continues concrete bridge structure on the expressway R2

Horut, Jakub January 2017 (has links)
The subject of master thesis is expressway R2 in Slovakia through a valley. Height of the construction is limited by a railway line and a local road. From two designed variants was chosen one and futher examined. The span lenght of bridge fields is 24,5 +5 x 30+24,5m. The structure was designed according to ultimate and serviceability limite states and construction stages were considered in model. In master thesis was processed structural design report, drawnings, visualization and engineering report.
