Slab bridge
Malý, Jan ; Muroň, Vlastimil (referee) ; Panáček, Josef (advisor)
Bachelor's thesis deals with the design of a road bridge over the Volyňka river. Three bridging variants were proposed, of which the bridge variant, whose supporting structure consists of an additional pre-stressed concrete slab, was chosen for subsequent detailed assessment. The variation with prestressed prefabricated girders with composite slab is chosen for more detailed assessment. Detailed structural design is made and selected parts of the construction are checked for ultimate and serviceability limit state by Eurocode. Calculation of load is made by manual way and then by exact way with program Scia Engineer 22. The results from both calculation methods are then compared. Detailed drawings and visualization are made as well.

Pedestrian bridge in Příbor
Škrachová, Ivana ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The subject of the bachelor thesis is about a concept of pedestrian bridge across the river Lubina in city Příbor. For final design of pedestrian bridge was made three preliminary designs of constructions and one of them was choosen for detailed processing, assessment and making drawings. The choosen variant is made as prestressed concrete's beam with parapets. For calculation of internal forces was used Scia Engineer Software. Assessment was made by method of ultimate and serviceability limit state. A process of constructio's works are not going be treated in this work.

A bridge with one field over a watercourse
Pylypenko, Jevhenij ; Požár, Michal (referee) ; Strnad, Jiří (advisor)
The thesis focuses on the design of the superstructure of a new concrete bridge, which replaces an old substandard construction. The bridge should serve for passing roadway across the river Šlapanka, in village Mírovka, Kraj Vysočina. The static system of new construction is a one-span post-tensioned slab which is simple supported on edges. Span length of the superstructure is 17,5 meters. From three variants of concrete slab cross-section, a trapezoidal-shaped one was chosen. Concrete slab was assessed by the ultimate limit state and service limit state according to recent standards (Eurocode). The preliminary design of post-tension was processed according to standards (CSN).

Pedestrian bridge across the river Svitava
Bezručová, Kristína ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
The aim of this thesis is the design and analysis of pedestrian bridge across the river Svitava. Three variants were designed. The variant of one-span frame construction with a parabolic haunch was chosen for analysis. The calculation of load effects was made in software Scie Engineer. For evaluation was used MS Excel. The design and assessment are according to the europien standards. The time dependent analysis is not treated in this work.

Strengthening of roof girders in production hall
Wawreczka, Karel ; Strnad, Jiří (referee) ; Klusáček, Ladislav (advisor)
The aim of my bachelor’s thesis is strengthening of girder roof construction in a production hall. The roof girders were designed 18 years ago in accordance with the Czech standards valid at that time. All the girders are now recalculated according to valid European norms. It is suggested to use prestressed cables guided along the girder construction. Because of the lack of space around the front of girders, it is designed to use prestressing from in the middle. In order to design the cable geometry and the biasing force, it was crucial to take into account shear resistance as well as constraining compressive stress in the concrete. Calculation of the effects of load is carried out by Scia Engineer 2015 computer software whereas Excel has been used for all the other calculations.

Design of the single span bridge in Vražné
Juřenčáková, Jana ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The subject of bachelor thesis is a design of single span bridge in Vražné. Within the scope of thesis there are three studies of bridge. Cast-in-place concrete slab super structure was found appropriate and further calculations were assessed. Length of span is 15,00 m. Internal forces were provided by SCIA Engineer and checked with manual calculation. The supporting structure was assessed for the ultimate limit state and serviceability limit state. Calculations were made according to valid standards and regulations.

Bridge on a ramp
Páteček, Tomáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The object of this diploma thesis is the design and review of a bridge on a ramp. The bridge is part of a junction between the expressway R35 and the highway D1. Three case studies were made. The bridge construction is solved as continuous beam with six spans. The resulting design was made of prestressed concrete according to valid standards. The gradual construction was taken into consideration.

Bridge over highway on a ramp
Tlamka, Tomáš ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The proposal is for new construction of a road bridge over the highway.Three options of solutions were proposed but only the option of connected girder slab beam of six fields was selected. This variant was assessed by static calculation. Static calculation is processed in accordance with European standards. Another important part of this thesis is also drawings, visualization, technical report and construction procedure.
