Footbridge in Nova Karolina in Ostrava
Havelka, Jiří ; Nečesal, Petr (referee) ; Marván, David (advisor)
The topic of the master’s thesis is a design of steel structure of footbridge. Footbridge goes across the roadways and railway. It is a design of a new structure in Nová Karolina in Ostrava. Span of footbridge is 200m. The footbridge’s superstructure is two steel arches angled toward each other and fixed to the foundation blocks. The supporting beam of the bridge deck is connected to the arch by tie-rods. The deck beam is a welded box section. The tie-rods are arranged to the V-shaped system. Deck of footpath is semi through type and orthotropic. The arches are connected at the top by lateral bracing. Lateral bracing is Saint Andrew's Cross type system.

Design of footbridge over the river Svratka in Brno
Konečný, Štěpán ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of this diploma thesis is to project and analyze a footbridge for pedestrians and cyclists over the Svratka river in Brno. The footbridge is single- spanned with a span of 64,7 m. Load-bearing structure is made of truss structure with upper deck. The bridge deck consists of floor beams and composite panels. Elements of the structure are made out of steel S355. The structure was designed in Scia Engineer 19.

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.

Design of railway arched bridge across the I/33 roadway
Uher, Michal ; Nečesal, Petr (referee) ; Marván, David (advisor)
This master thesis content is alternative design of one span single-railed steel bridge. The bridge is located in km 44,179 on the track Jaroměř - Dvůr Králové. Crossing barrier is roadway I/33. The teoretical distance between supports is 42 m. Main bearing structure is designed as Langer beam. Structure consist of beams, arcs, suspenders, bridge deck with longitudinal and transversal bracings. Elements of the structure are made out of steel S355J2+N, S235J2+N, S355NL. The bridge is designed according to current standards ČSN EN.

Design of steel-concrete arch structure of footbridge over the river Svratka
Vraňanová, Veronika ; Marván, David (referee) ; Nečesal, Petr (advisor)
The main goal of this diploma thesis was to project a design of arch bridge‘s framework over the Svratka river. This single-span bridge has the span of 52,5m. The framework is constructed from a pair of beams, suspended from the pair of beams bent towards each other. The bridge deck is coupled with steel crosspieces. The construction design was executed in computing programme Dlubal RFEM 5.07. The individual components of the framework were assessed in Microsoft Excel. The calculation considered the load of wind and pedestrians’ movement and their effect on the dynamics of the construction. The phases of development were also considered. Assessments of coupled cross-section, main beams of steel construction, tension systems and selected construction joints were executed in a static calculation. Moreover, a design of a bearing and a bridge plug joint. Finally, a drawing documentation and a final report were prepared in regards with the requirements. The construction design and its assessment were executed according to valid standards.

Design of steel-concrete composite structure of road box girder bridge on by-road of Bludov
Kuba, Michal ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of this work is design and assessment of the box-girder road bridge on by-road of Bludov. Bridge is designed as composite steel concrete bridge with 5 spans with distances between supports of 31,25 m; 40,0 m; 60,0 m; 60,0 m and 40,35 m. Main bearing structure is designed as open steel box-girder with reinforced concrete deck. Box girder is braced with longitudinal and transversal bracings. Main structure is separated for each traffic direction. The bridge crosses river Morava and railway in 2nd and 3rd span, respectively. The category of road I/44 is S 21,5/100. The height of steel box girder is designed as 2,5 m. Bridge will be built by incremental launching method, with in-situ casted concrete deck afterwards. The bridge is designed according to current standards. Supporting elements are designed from steel of class S 355 and concrete of class C35/45.

Design of steel-concrete composite structure of road bridge in Trenčín
Doležal, Tomáš ; Marván, David (referee) ; Nečesal, Petr (advisor)
The aim of diploma thesis was to design alternative of composite road bridge in Trenčín. The bridge beam is designed as continuous with theoretical span of 65 m + 106 m + 65 m. Permanent load, climatic load (uniform and nonuniform temperature variation, windload), shrinkage, differential settlement and traffic load were taken into consideration according to Eurocodes. Technical report, static report, drawings, bill of quantities are included. Computational model for evaluation of internal forces was carried out in SCIA Engineer software.

Bridge over the Olše river in Návsí
Mendroková, Magda ; Nečesal, Petr (referee) ; Marván, David (advisor)
The diploma thesis deals with design and assessment of steel arched bridge with the semi through bridge deck placed on the third-class road. This steel structure is drawn up to bridge water barrier – the river Olše in Návsí. The distance between axes lay on abutments is 48,5 meters. The bridge´s supporting structure consists of two steel arches angled towards each other and fastened to the foundation blocks. The supporting beam of the bridge deck is tied to the arch by tie-rods. The tie-rods are designed to the V-shaped system.
