Steel Footbridge
Janíková, Dita ; Barnat, Jan (referee) ; Bajer, Miroslav (advisor)
The diploma thesis is focused on a design and appraisal of a steel load bearing construction of footbridge. The footbridge builds a new bridge across the river Ostravice in Sviadnov at Frýdek-Místek. The main subject of the diploma thesis was preparation of three variants for the footbridge. All variants were evaluated and the best one was elaborated in depth. It is a footbridge with a total span of 57 metres with a load bearing construction created two arches bent down to each orther. There is an orthotropic bridge deck with main outer lenghthways girders on the arches.

One span cable-supported bridge
Kučerka, Ján ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The theme of this bachelor thesis is the design of a footbridge across the river. The design is processed by two options. The chosen option is designed as a cable-stayed construction supported by cables. Bridge is designed as perpendicular with total length 66,225m. Superstructure is made by prestressed monolithic deck suspended by cables from sloping pylon. Considerable part of the thesis is devoted to creating a so-called initial state. The calculation of internal forces was done by calculation software Scia Engineer 2018. The design of prestressing force, assessment of ultimate limit state and serviceability limit state were done by hand according to the valid standards and regulations. Bearing capacity assessment of pylon was solved by IDEA StatiCa 9 software and some results were verified by hand. The thesis disregards rheological effects and stages of construction.

Pedestrian Bridge
Hibš, Daniel ; Kocourek,, Petr (referee) ; Stráský, Jiří (advisor)
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.

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.

Arch bridge across the valley
Velešík, Marek ; Zlatuška, Karel (referee) ; Nečas, Radim (advisor)
The main focus of this master thesis is the design and assessments of the bridge structure consist of a stress ribbon supported by a steel arch. Three preliminary studies of pedestrian bridges above the valley were created and the one with semi-through deck supported by arch through cables was chosen to detail processing. This thesis includes a chapter, which deals with finding the ideal shape of arch. The computational beam model for the analysis of the structure was created in software Ansys Mechanical including the construction stages. The correctness of the computational model was verified by the secondary model created in the software Midas Civil. For evaluation of the structure in crosswise direction was created slab model in software Midas Civil. The structure was evaluated considering the ultimate serviceability state and ultimate limit state according to currently valid standards. The thesis also includes dynamic analysis.

The Footbridge for Pedestrians across the Berounka River
Kováčová, Kristýna ; Buchta, Stanislav (referee) ; Šmak, Milan (advisor)
The aim of the Bachelor´s thesis is a static design of the footbridge for pedestrians across the Berounka river. The structure is created as three-dimensional model. The internal forces are calculated by FEM programme Scia Engineer 15.1. The load-bearing elements are designed with these forces. The length of the footbridge is 12,12 m, width 2,9 m and height 1,5 m. The footbridge is mostly made of glued laminated timber. Others materials are steel and timber. The steel is used fort connectors, wind bracing elements and bracing semi-frames. The construction is solved as timber beam with through-spain. The footbridge consists of two timber beams, floor beams, stringers and wind bracing elements.

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.

Multi-Storey Administrative Building
Tomeš, Martin ; Bajer, Miroslav (referee) ; Barnat, Jan (advisor)
The diploma thesis deals with the design of the administrative building from steel S420, S355 and concrete C25 / 30 with reinforcement made of steel B500B. The office building is a column-type with reinforced concrete ceiling. The building is equipped with a footbridge on the 10th floor. Two variants have been elaborated. Both of them were calculated in the program Scia Engineer. The winning variant is processed in detail.

An assessment of a bridge construction on a dynamic load
Součková, Markéta ; Kala, Jiří (referee) ; Salajka, Vlastislav (advisor)
Diploma thesis deas with static and dynamic analysis of a steel arch footbridge. The footbridge structure 3D model was created in program ANSYS 12.1 and afterwards were made static and modal analysis on this computational model. Based on the results of~modal analysis was applied to design of dynamic wind loading on the model according to norms ČSN EN. The effects of this burden has been calculated steady response at resonance from harmonic analysis according to ČSN P EN 1991-2-4. To report according to ČSN EN 1991-1-4 was designed substitute quasistatic forces corresponding loads of wind on the construction and for evaluation was used static analysis.
