Bridge across river and railway line on town bypass
Němec, Martin ; Kusák, Ivan (referee) ; Navrátil, Jaroslav (advisor)
This thesis deals with a bridging design of a river and ČD railway at the town bypass . The construction of the bridge is made as a running girder used for the road S 11,5/70 crossing the river Šlapanka and the railway line Šatov – Kolín, TÚ 1201. The work comprises some alternative solutions to this bridging design as well, especially alternatives of cross-section, static system and bridge building process. The static design solution made on a computer includes TDA (Time Dependant Analysis). All suggested alternatives consist of a design of prestressing and rough assessment of chosen sections. The next goal of this thesis is working-out of a project based on chosen alternative of the main bearing construction and a rough calculation of the foundation.

Calculation of Prestressed Concrete Beam
Vítek, Filip ; Pokorný, Přemysl (referee) ; Malášek, Jiří (advisor)
This thesis is focused on the description of the calculation of prestressed concrete beams. The introductory chapter discusses the bias and distribution of prestressed concrete. The second chapter describes materials used for the production of prestressed concrete and its characteristics. The following chapters describe the calculation of changes of prestressing and their effects on the structure, prestressing methods and a limit state where the prestressed concrete is controlled. A model example of calculation is shown in the last chapter.

Prestressed road bridge in Staré Město
Juříček, Lukáš ; Nečas, Radim (referee) ; Koláček, Jan (advisor)
The thesis proposes the design of main structure concrete bridge,which is transferring highway road across the river Krupá in Staré Město.It is simple span bridge with length of 14,995 m.For the next calculation were chosen post tensioned concrete trapeizodal slab.The slab is assessment on serviceability limit state and ultimate limit state according to valid European standarts.

Slab bridge in Staré Město
Pejčoch, Karel ; Panáček, Josef (referee) ; Koláček, Jan (advisor)
The aim of this bachelor thesis is to design of bridge construction over the river of Krupá located near the city of Staré Město. The load bearing system is composed from one prestressed concrete span. The structural design was made in two variants, which were compared between them. For calculations of first way was used the software of Scia Engineering and second way was calculated by simplified manual method of effective width. All calculations were performed according to actual standard EN.

Slab bridge in Český Krumlov
Luberová, Lucie ; Koláček, Jan (referee) ; Panáček, Josef (advisor)
The subject of this bachelor’s thesis is the design a new supporting bridge construction across creek Polečnice in Český Krumlov. This object is located on the 1st class road I/39, at kilometer 13,027. The objective is the design of a perpendicular one-span construction, which is proposed in three variants. The first variant is a slab from post-tensioned concrete with a variable height of max. 0,950 m. The second variant is composed of prefabricated concrete beams VSTI 2000-21/0,9 coupled with a reinforced concrete slab with a thickness of 0,200 m. The third variant is similarly of prefabricated concrete beams T93-21/0,85 coupled with a reinforced concrete slab with a thickness 0,200 m. For detailed assessment the first variant was chosen with a length of bridging of 18,080m. The calculation of load effects is done by computer softwares Scia Engineer 14 and IDEA StatiCa and compared with a manual calculation according to current standards.

Pedestrian bridge across the river Dyje
Uher, Lukáš ; Koláček, Jan (referee) ; Nečas, Radim (advisor)
This bachelor thesis aims to design a structure of pedestrian bridge over the river Dyje. Therefore, three outlines of bridging were drafted. The main propose of this thesis is to make a static analysis of a respective outline, which is the structure of a steel arch supporting a prestressed concrete deck. The calculations were made using the Scia Engineer software and the evaluation is done in MS Excel. The design is drafted in accordance with ČSN EN 1992. This thesis, however, does not deal with the time dependent analysis.

Slab bridge over a local brook
Olšák, Martin ; Hochman, Dominik (referee) ; Nečas, Radim (advisor)
The subject of this bachelor’s thesis is to design a one field slab bridge over a local brook. The supporting structure is from prestressed concrete with the lenght of 18,00 m. The load effects is calculated by Scia Engineer 2013.1 and compared with manual calculation. The supporting structure is assessed for the ultimate limit state and serviceability limit state. Static assessment is done by hand calculation acording to CSN EN 1992-2.

Design of the prestressed ceeling structure
Pírková, Barbora ; Chalabala, Jiří (referee) ; Klusáček, Ladislav (advisor)
This bachelor’s thesis deals with the design and the solution of a prestressed ceiling structure of a building. The preliminary design is established using the method of balancing the equivalent load which is limited by choice of the average normal stress and the method of a surface of feasible prestress. The aim of this thesis is to assess whether such proposed prestressed slab meets the limit states of usability and load capacity and ultimate assessment of the feasibility of the design of this type of construction.

Design of the slab bridge
Strouhalová, Petra ; Krejčík, Vladimír (referee) ; Klusáček, Ladislav (advisor)
This thesis deals with design and solution of road slab bridge structure. Draft prestressing force is processed using the load balancing, the thickness of the slab is consedered in five variants. The aim of this thesis is to determine which option is appropriate for prestressing and which not and subsequently one selected variant design.

Design of a slab bridge
Strachoň, Martin ; Nováček, Jan (referee) ; Nečas, Radim (advisor)
This thesis deals with the design and solution of a slab bridge structure. In first chapter are presented two options of bridge and one them is selected to next counting. The aim of this work was to design and evaluate the structure on the basis of ultimate limit states and serviceability limit states according to applicable EN standards.
