Steel structure of a multi-functional building
Havíř, František ; Pilgr, Milan (referee) ; Štrba, Michal (advisor)
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.

Footbridge
Grussmann, Jan ; Straka, Bohumil (referee) ; Sýkora, Karel (advisor)
Master´s thesis deals with design and complex static assessment of timber roofed footbridge structural system. The calculation part is divided into three main chapters, that are dedicated to determine load impacts on structure, to particular structural and roof members assessment and also to design details of connections. The lower part of structure is formed by flat arched main beams of glued laminated timber, floor beams, stringers and under-deck bracing. The upper part of footbridge is formed by structure of gabled roof and additional bracings. Transversal frames of footbridge copy the shape of arch and they are arranged orthogonally to its axis. They form a radial fan with commom centre in the longitudinal direction. The static scheme of structure is thought as a statically undefinite system thanks to the bedrock surrounding the footbridge.

Pedestrian bridge across the river Labe
Libiger, Martin ; Trenz, Jan (referee) ; Nečas, Radim (advisor)
The thesis deals with a design of the river Labe bridging in the city Hradec Kralove. In order to make option for cyclists and pedistrians to cross between shores. There were made three design variants. For detailed solution curved twin-arm arched structure was chosen. The aim of the thesis was design and assessment of Bering strucutre of the footbridge according ultimate limit states and serviceability limit state given by valid Eurocodes.

Analysis of the wind effect on the construction
Tačner, Jan ; Hradil, Petr (referee) ; Kala, Jiří (advisor)
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.

Suspension footbridge across the river
Chumová, Petra ; Bartoň, Jaroslav (referee) ; Nečas, Radim (advisor)
The subject of the thesis is to design a suspension footbridge over a river basin. Three different studies were created for the assigned problem. The suspension footbridge was chosen for the thorough elaboration. The most important part of the thesis is the static solution of the supporting structure. The structure model for calculation of impacts of selected strains including the impact of the footbridge construction was created in computational software Ansys. Assessment and dimensioning was carried out using manual calculation according the principles of limit states and applicable standards.

Pedestrian bridge supported by steel arch
Kadrmanová, Lucie ; Formánek, Ing Martin (referee) ; Nečas, Radim (advisor)
The aim of this master’s thesis is to design a footbridge across a river. The main objective is design and analysis of a footbridge supported by a steel arch. Stress ribbon is suspended on steel arch using hangers. The analysis of the structure has been carried out using ANSYS 12.0 and Nemetschek SCIA 2011.1 software, design checks using EXCEL in accordance with Eurocodes. Time dependent analysis was considered.

Static and dynamic analysis of Prestressed bridge structure
Hokeš, Filip ; Nečas, Radim (referee) ; Kala, Jiří (advisor)
The main objective of the thesis is to perform static and dynamic analysis of prestressed concrete bridge structures in computational system ANSYS. For the analysis was chosen footbridge over the river Svratka in Brno. In relation to this topic are solved various types of modeling prestress at a finite element level. Before analyzing the footbridge is analyzed in detail the static system and the corresponding final geometry of the structure. Knowledge of the functioning of the static system is used to build the computational model of the structure, on which is subsequently performed static and dynamic analysis.

Urban design of waterfront in Třebíč
Vacek, Jiří ; Ležatka,, Lukáš (referee) ; Pavlovský, Tomáš (advisor)
Thesis is concerning urbanistic treatment of Jihlava river embankment in the city of Třebíč. Tries to find cause for urban non-functionality of the area within local and wider context to its surroundings. Offers possible solution for rehabilitation of the urbanistic function of the embankment, including putting the embankment into role of important passageway, improving its bounds to the surroundings and active role in city's everyday life.

Wind loading of lightweight bridge-like structure
Hrubý, Pavel ; Kala, Jiří (referee) ; Nevařil, Aleš (advisor)
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.

Arch structure footbridge
Machala, Zdeněk ; Glovina, Filip (referee) ; Nečas, Radim (advisor)
The subject of this master’s thesis is to design an arch structure of a footbridge. The bridge deck will be formed by a stress ribbon and could be divided into three parts. The middle part will be suspended (on the outer edges) on composite steel and concrete arches. Outer parts of the bridge deck will be formed by stress ribbons. The model of this construction is created in a computational program ANSYS and the solution is non-linear. The design is according to European standards.
