Design and optimization of the arch structure
Herka, Martin ; Vácha, Jaroslav (referee) ; Štěpánek, Petr (advisor)
Diploma thesis deals with a design of concrete arch structure. There was made a preliminary design of concrete structure of a buried arch bridge. Subsequently was the shape of arch structure optimized to oblige the requirements of real buried arch bridge structure. There is included static calculation of the ecoduct construction. It is developed detailed drawings

The roofing of amphitheatre in Vizovice
Kuchtová, Ludmila ; Štrba, Michal (referee) ; Šmak, Milan (advisor)
The scope of this bachelor’s thesis is to design roofing over a natural amphitheater stage in Vizovice. The structure is designed as a variable structure in verison of both steel and timber. Each solution has a different structural composition. The layout is triangular with width of 18 meters and length of 15 meters. The height of the roofing is considered to be 9 meters.

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.

Pedestrian bridge across the lagoon
Bezručová, Kristína ; Kaláb,, Pavel (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the lagoon. Three variants were designed. The variant of structure, which combines stress ribbon with steel arches, was chosen for analysis. There is a chapter in this thesis which deals with an ideal shape of arches for different types of loads. The calculation of load effects was made in software Ansys 17.0, considering scnstruction stages. Ultimate limit state and state limit state are evaluated. For evaluation of concrete cross sections was used MS Excel. Steel cross sections were evaluated in software Ansys 17.0. d Dynamic behaviour of construction was assessed. The mode shapes and natural frequencies were calculated. The harmonic excitation response was studied. The loss of stability was checked. The design and assessment are according to the european standards.

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.

Design of footbridge over I / 11 road in Ostrava
Mikhno, Yevgeniy ; Nečesal, Petr (referee) ; Marván, David (advisor)
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.

Theatre House in Kuřim
Petr, Radovan ; Bajer, Miroslav (referee) ; Barnat, Jan (advisor)
The theme of the master´s theses is to design a wooden structure of city theater with internal steel construction. The concept of wooden structure is developed in two versions according to standard ČSN EN. The theses solve the static effect of the construction and design of individual parts and materials. Theater has dimensions 49.0 x 25.6 m, max. height of 12.5 meters. The construstion is devise to withstand a weight and applicability. The supporting structure of the roof is solved using by 13 arched plate girders. The second variant is designed as arched truss girders. The gable wall is glassed-in, glass envelopes support by wooden structure with columns and side runners. The work also includes solutions for joins and construction details. The structure was solved in the program RSTAB Dlubal 8. The assessment of the components was done using additional module TIMBER Pro. First Variant of plate girder was checking by manual report. The work includes drawings.

Pedestrian bridge in Hradec nad Moravicí
Janeček, Tomáš ; Horáček, Martin (referee) ; Pešek, Ondřej (advisor)
The aim of this thesis was to design and assess a footbridge over the Moravice River for pedestrians and cyclists, as the existing footbridge is in poor condition and it is narrow, so it doesn't allow convenient movement of pedestrians and cyclists. The footbridge is located in Hradec nad Moravicí and connects Žimrovická Street with the sports complex on Na Potůčku Street. First, four different variants were considered, from which the most advantageous design was selected, and it was then solved in more detail. The winning variant is a steel arch footbridge with a lower bridge deck, while the bridge deck is suspended on two rigid arches by means of tie bars. The span of the footbridge is 28 m, the span of the arch is 5.5 m, and the entire structure is made of S 235 steel except for the screws and system tie bars.

Pedestrian bridge over the Svratka river in Brno
Škrabal, Jan ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The subject of this bachelor thesis is the structural design of a one span pedestrian bridge over the Svratka River in Brno. The arch bridge with axially suspended deck on a steel arch was chosen for the assessment out of three options. It is a self-anchored structure, so that the tensile force in the deck must be eliminated by prestressing. For the calculation of internal forces the Scia Engineer 18.1 program was used. Two models were created – one for the longitudinal direction, the second one for transverse direction. Structural design was handled according to the valid standards and regulations.

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.
