Lávka pro pěší / Pedestrian Bridge

Hibš, Daniel January 2019 (has links)
This diploma thesis deals with the design of a new bridge construction over a multi-lane communication. The converted road is a pedestrian and biking trail connecting significant agglomerations. Three studies were worked out in this thesis and the C variant was selected for further detailed processing. It is an unsymmetrical suspended bridge with a cast-in-place deck. In the section above the communication, the bridge is made up of prefabricated segments. Suspension of the structure is made of two sloping pylons forming a V-shape. The analysis of the construction was carried out in the MIDAS Civil program, where a complete model of construction was entered, including a subsequent estacade. The model describes the construction process and includes creep and shrinkage of the concrete. The traffic, temperature and wind loads were used. The design was assessed for the ultimate limit states and serviceability limit states. The assessment was carried out in the IDEA StatiCa program, supplemented by manual calculations. The static calculations also include assessment of the harmonic response. Subsequently, overview drawings, detailed drawings and visualizations were developed.

Lávka pro pěší přes řeku Dyji v Břeclavi / Pedestrian Footbridge across the Dyje River in Břeclav

Pham, Hoang Anh January 2019 (has links)
This thesis deals with structural design of a steel frame footbridge with wheelchair access, which will lead pedestrian and cyclists‘ traffic over the river Thaya in Břeclav. The footbridge is a structure of one field, lightness of a bridge opening is 58,92 m and a span length is 60,25 m. A light width of an area between rails is 2,5 m. The footbridge is constructed of a truss beam cable – stayed bridge on an oblique pylon of 20,0 m length and a preloaded steel suspender. The thesis was processed according to valid standards ČSN EN.

Návrh lávky přes silnici I/11 v Ostravě / Design of footbridge over I / 11 road in Ostrava

Mikhno, Yevgeniy January 2020 (has links)
The aim of this bachelor thesis is variant design and assessment of loadbearing structure of steel footbridge over I/11 route. Main superstructure will have two steel arched beams joined with lower orthotropic deck using suspenders in the „V“ shape. For assessment of superstructure a three-dimensional structural computational model was created in software Dlubal RFEM 5.20. The span of the footbridge is 48,71 m, free width is 4 m, height is 7,5 m. The structure was designed according to currently valid standarts to the ultimate limit state and serviceability limit state. Supporting elements are designed from steel of class S355.

Zatížení větrem lehké mostní konstrukce / Wind loading of lightweight bridge-like structure

Hrubý, Pavel January 2013 (has links)
The present thesis is concerned with air flow over lightweight footbridge. Special attention is paid to flow-induced instabilities. The thesis opens with a theoretical elaboration on the phenomena related to the research matter. The next part investigates air flow over footbridge in a specific situation using numerical simulation in the Ansys CFX software. Finally, results are discussed in the light of chosen theoretical framework and relevant conclusions are presented.

Lávka pro pěší / Footbridge

Drexler, Martin January 2014 (has links)
This thesis deals with the design and assessment of the wooden footbridge. The structure is designed for the locality of the village Loučná nad Desnou acrros the river Desná. Span of the footbridge is 30m, and the width is 4m. The footbridge is covered with a saddle roof. The main supporting elements are two triple joint arcs with intermediate bridge deck. The bridge deck is made of two main beams and nine cross members, with always two longitudinal members in between them. Roofing is of nine cross-bindings, which are connected by purlins and top purlin. The stability of the whole structure is stiffened by the horizontal longitudinal stiffeners in the top and bottom surface and vertical longitudinal stiffener in the roof. The main load-bearing elements are made of glued laminated timber, the other elements are made of solid timber. Stiffeners are made of steel rods.

Analýza působení větru na stavební konstrukci / Analysis of the wind effect on the construction

Tačner, Jan January 2015 (has links)
Diploma thesis deals with static and dynamic analyses of a slender bridge structure behavior. The footbridge structure model was created in ANSYS 14.5 programing system. Static and a modal analyses were made afterwards and according to these analyses dynamic wind load and dynamic pedestrian load were applied. Wind load was applied as option of deck without a handrail and as option of deck with fully airtight handrail. Pedestrians were perceived as group of pedestrians and as a sparse crowd. Both applied loads were solved by harmonic analyses. Results of these analyses are resonance curves and tables of accleration.

Ocelová lávka pro pěší / Steel Footbridge

Bartoň, Radek January 2015 (has links)
This diploma thesis contains a study of current composite structure of footbridge and in part II design and assessment of steel structure of footbridge for pedestrians and cyclists placed on current footbridge location. Current footbridge is located on "nábřeží Dukelských hrdinů" in Rožnov pod Radhoštěm. In part I, assessment of the current composite structure of footbridge is done, using ČSN and ČSN EN standards for adjusted static behavior of the structure. Comparison of both assessments is made and also with an original assessment from 1988. In part II, design and assessment of steel structure of footbridge placed on currents footbridge location described in part I is done.The structure was designed as two vierendeels trusses connected with cross beams, supporting concrete bridge deck. 9 variants were examined, differing with truss height and the number of verticals. Detailed design and assessment for parts of the structure is done for the chosen variant.

Ocelová konstrukce multifunkční budovy / Steel structure of a multi-functional building

Havíř, František January 2015 (has links)
The aim of this master's thesis is to design the steel construction of a multifunctional building in the cadastral area of Brno-Bohunice. Multifunctional building consists of two identical buildings - A and B. Floor plan dimensions are 40.0 x 40.0 meters and height of 33,8 meters. Both objects have the 1st floor of the overall height of 5,0 m, each additional floors 3,5 m. The plan shape of the building is a square 40 x 40 m with bevel in the corners with a length of 8 m. In the middle of the building is roofed atrium 8 x 8 m. The buildings are in the 5th floor connected with the enclosed footbridge with a length of 10.0 meters. The main structure consists of two buildings columns and girders. Columns are alternatively solved as the composite steel and concrete structures with closed section filled with concrete or concreted steel profile. The girders are made of castellated beams. Among the girders are embedded solid panel joists and girders, coupled with the composite steel and concrete slab. Spatial rigidity besides the composite slabs provide rods placed around the atrium and in the corners of the building. The main structure of the footbridge consists of two inclined arched beams on which is placed stringer of the footbridge.

Skorunka, Ondřej January 2016 (has links)
Diploma thesis deals with static and dynamic analysis of a wooden arch footbridge. The computational model of the structure was created in ANSYS 15. Dynamic forces from wind and horses were applied to the model based on the modal analysis. The effects of these forces at resonance were evaluated by harmonic analysis.
