Design of highway bridge
Luberová, Lucie ; Formánek, Ing Martin (referee) ; Zich, Miloš (advisor)
The subject of this bachelo r’s thesis is the design a new supporting bridge construction in Prešovský kraj, district Levoča the territory of Slovak Republic. This object is located on the highway D 26,5/120, at kilometer 13,499 795 and communication of third class – 131-00 bridges. The objective is the design of a perpendicular four-span construction, which is proposed in three variants. The first variant is a chamber girder with inclined walls from post-tensioned concrete height 2,480 m. The second variant is composed of two beamed cross-section and the third variant is composed of one beamed cross-section. For detailed assessment the first variant was chosen with a length of bridging of 166,000 m. The calculation of load effects is done by software Scia Engineer and compared with a manual calculation according to current standards. This bridge is designed according to limit states, construction´s influence on design is taking into consideration. Structural analysis, well arranged drawings and visualization are elaborated in this thesis too.

Track Bridge Interaction
Kapounek, Jan ; Kubelka, Jan (referee) ; Plášek, Otto (advisor)
This thesis focuses on the analysis of different approaches to the evaluation of the combined response of bridge structure and continuous welded rail on 5 planned bridges on high-speed railway in the Czech Republic in the stage of Land Use Permission. The output of the analysis of these bridges is the indication and description of problematic points occurring in the methodology as well as the development of recommended steps for the calculation of the combined response of structure and track to variable actions by the method of Complex Analysis for bridges on high-speed lines in the Czech Republic. Based on this recommended procedure, a simple bridge model is created.

Design of the footbridge over the railway
Mertová, Eliška ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
The aim of this bachelor´s thesis is a design of a new footbridge over the railway instead of an existing reinforced concrete pedestrian bridge in a compound of the cement factory in Mokrá at Brno. The footbridge is used to the transfer pedestrians over the mentioned train. The work is composed of the design of the pedestrian bridge as a continuous frame structure, including making a model of the bridge for an analysis of internal forces, design and checking the structure for the ultimate and serviceability limit state. A calculation of load effects is processed by the computer software Scia Engineer 2013. The construction stage analysis wasn´t applied in the structural calculations.

Prestressed bridge on the expressway
Juřenčáková, Jana ; Zlatuška, Karel (referee) ; Koláček, Jan (advisor)
The purpose of the diploma thesis is to design a expressway bridge over the river Vsetínská Bečva. The bridge is located between Valašské Meziříčí and Vsetín. Separate superstructures are designed for each directions of the expressway. The right superstructure, which is wider, is considered for detailed design. Two variants were proposed, A double T beam superstructure and a box girder superstructure. The three span box girder superstructure was chosen for the design. Spans are 48+65+48 m long. Two options of construction process of the superstructure were proposed. This bridge is designed according to the limit states, the influence of construction process is considered. Structural models of construction were made as a finite element model and a plate model. Structural analysis, drawings and visualization were developed.

Bridge across the Lochkov Valley
Zvolánek, Lukáš ; Juchelková, Pavlína (referee) ; Stráský, Jiří (advisor)
The theme of the Master’s thesis is detailed design of superstructure for selected option of the bridge. The bridge carries highway across Lochkov valley. The superstructure, 6 spans, is made of one cell continuous box beam with large overhangs supported by prefabricated struts. The continuous beam is in plan curvature. As the first, side spans 1, 5, 6 will be casting on fixed scaffolding. Spans 2 and 4 will be casting using cantilever method, gradually hanging superstructure up. For the casting the main span will also be using cantilever method, gradually removing temporary hangers of adjacent spans. The structure was analysed according to limit states. The thesis also includes a time dependent analysis of the structure and solution of influence construction on its design.

Steel railway bridge across a watercourse
Slezák, Jaroslav ; Pilgr, Milan (referee) ; Karmazínová, Marcela (advisor)
The aim of the thesis was to design and assess a steel railway monorail bridge over a watercourse. The bridge consists of three spans of 33 + 75 + 33 m. In the middle span, the main beam is reinforced with a 10 m arch and tie rods. The width of the bridge is 7.8 m. The axial distance of the main beams is 7.1. It is a bridge with a lower orthotropic steel deck.

Bridge over a brook and local road
Kučerová, Miroslava ; Řehulka, Martin (referee) ; Panáček, Josef (advisor)
The aim of the diploma thesis is the proposal of a bridge structure in the direction of Frýdek-Místek - Mosty u Jablunkova. A bridge is used to overcome the local road and Malý javorový stream. From three alternatives is selected a post-tensioned two-beam concrete struction and assessed according to the limit states. It is developed clear and detail drawings and visualization of the bridge.

Multi-span double teebridge
Alušic, Michal ; Řeřucha, Kamil (referee) ; Koláček, Jan (advisor)
Main purpose of the diploma thesis is to design a multi-span double-girder bridge which spans the valley of a river. The bridge spans main road of 1st class. Main superstructure of a bridge is made of prestressed concrete which is built span by span. Structure was designed according to limit states in construction stages as well as during the service. Everything was designed according to the latest European normatives. It contains static calculation and drawing documentation.

Continues concrete bridge structure on the expressway R2
Horut, Jakub ; Sliwka, Pavel (referee) ; Koláček, Jan (advisor)
The subject of master thesis is expressway R2 in Slovakia through a valley. Height of the construction is limited by a railway line and a local road. From two designed variants was chosen one and futher examined. The span lenght of bridge fields is 24,5 +5 x 30+24,5m. The structure was designed according to ultimate and serviceability limite states and construction stages were considered in model. In master thesis was processed structural design report, drawnings, visualization and engineering report.

Bridge on I/38 road.
Novotný, Tomáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The final thesis is focused on design of valley bridging on I/38 road at the Havlickuv Brod bypass. The thesis contains study of the bridging area. For detailed assessment was chosen, from three variants, a two-beam cross-section girder of 4 spans. Load-bearing structure is designed as cast-in-place, post-tensioned, concreted at fixed falsework without phased construction. The serviceability limit state and the ultimate limit state were assessed. The thesis contains, apart from structural design, drawings and visualizations of the bridge.
