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

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.

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 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.

Road and tram bridge
Vošček, Martin ; Štrba, Michal (referee) ; Brosch, Petr (advisor)
The subject of this Diploma Thesis is to develop different alternatives of the road and tram bridge. It is a river bridge with the length of 52,5 m. There are compared two proposals, while in the first proposal it is an arch bridge with the tension bars. The second proposal which is also finalized as the winning proposal is the truss structure. Both proposals have composite deck. The structure is designed from steel S355 and concrete C35/45. The load bearing structure is designed in accordance with applicable technical standards.

Plan curved structures supported by arches
Trenz, Jan ; Zich, Miloš (referee) ; Vítek,, Jan (referee) ; Stráský, Jiří (advisor)
The aim of this doctoral thesis is the research of the plan curved footbridges with the deck supported by arch. The research is preceded by the survey of present findings about arch structures with upper deck. The summary of reasons and difficulties of design of plan curved structures follows. The appropriate approach for design of plan curved structure is searched on the basis of methods for design of straight structure. The design of arch which is subjected to minimal bending moments is emphasised. At first, the structure is designed in the same way as straight structure and the limit plan curvature (for which the method is not suitable anymore) is sought. Then the approach based on method of inversion of suspended cable is examined and adapted for designing of plan curved arch geometry. The approach is thoroughly analysed through calculation model and experimentally verified on physical model in scale 1:10. The process of design, construction and testing of the physical model is described in detail. Measured deformations and stresses are compared with expected behaviour based on numerical analysis. The comparison proves good correlation between calculation and measurement, as well as high load bearing capacity of the structure.

Railway station
Hodonský, Petr ; Bajer, Miroslav (referee) ; Barnat, Jan (advisor)
The content of the diploma thesis is design and assessment of railway station steel structure. It is a two-nave building with a length of 198m. The bigger nave span is 40m and it is 14m high. The smaller nave is 11m high and its span is 25m. The total width of the structure is 65 meters. The main construction material is S355JR steel. The supporting structure of the hall is formed by a curved planar trusses with axial distance of 6 meters. The transverse direction also consists of column that bears two main trusses. The static analysis of the main bearing parts of the structure, including joints and details is processed. The calculation were made in accordance with the Czech technical norms CSN EN.
