Preparation and implementation of construction and technical survey of prestressed bridge structure
Kubová, Klaudie ; Sedláček, Ondřej (referee) ; Anton, Ondřej (advisor)
The bachelor's thesis deals with the technical survey of the load-bearing structure of the left part of prestressed motorway bridge D2-058..2. The bridge is located on the border between the Czechia and Slovakia, and it was built in 1980. The work is focused on locating the prestressing reinforcement of prefabricated beams and determining its condition. The theoretical part describes the principle of static action of reinforced and prestressed concrete, categorization of technical surveys of structures and diagnostic methods. The work also presents specific diagnostic methods for determining the position and condition of prestressing reinforcement. In the practical part, the work deals with the analysis of beams by means of ground penetrating radar and probes for analysis of the condition of reinforcement. The outcome of the work is a study of the deviations of the position of prestressing cables from the original project documentation and determination of their condition in terms of corrosion degree and grouting.

Bridge over the Jihlava river
Hibš, Daniel ; Klusáček, Ladislav (referee) ; Panáček, Josef (advisor)
This bachelor thesis deals with the design of a new bridge construction over the Jihlava river in Luka nad Jihlavou. The bridge is located on the road III/4044 at stationing 0,033 km. The bridge evidence number is 4044-1. Three studies were worked out in this thesis. First variant of load-bearing structure projects prestressed beams with composite slab, the next variant suggests dual girder construction and the third variant is prestressed concrete slab. The first study was selected – the bridge made of post-tensioned prefabricated beams with composited reinforced concrete slab. The calculation was carried out in the SCIA Engineer program, and selected outputs were checked by manual calculation. In addition, the time dependent analysis with construction phases was performed.

Bridge over a roundel
Gross, Tomáš ; Klusáček, Ladislav (referee) ; Panáček, Josef (advisor)
The bachelor thesis deals with design construction of two new bridges over the roundabout. Roundabout is part of exit 354 of the D1 motorway. Bridges is located at kilometer 278.786 on road I /11. Three studies were developed. Design of the first study is post-tensioned prefabricated I beams, which are composite reinforced concrete slab. Design of a second study is post-tensioned slab-beam. Design of a third study is post-tensioned doublebeam. For a more detailed assessment of the study was chosen No. 1 - post-tensioned prefabricated I beams, which are composite reinforced concrete slab. Calculating the effects of the load is solved in Scia Engineer. Construction phase was carried out using TDA - temporal analysis. Testimonials are partially controlled by manual calculation.

Bridge over the Rajčanka river
Kavecký, Jakub ; Svoboda, Adam (referee) ; Panáček, Josef (advisor)
The aim of the bachelor thesis was to design a bridge over the Rajčanka river. The bridge is single field with perpendicular crossing of the watercourse. Three variants were created, one of which was the subject of thesis. For a detailed dimensioning, a variant with prefabricated additional-prestressed beams coupled with a concrete slab was selected. The static´s models were created in software SCIA Engineer 19.1 and IDEA StatiCa. Internal forces and load combinations were compiled including time-dependent construction and rheological phenomena. The reports were processed by manual calculation, according with the Eurocode. Climatic influences, such as wind and snow, as well as braking force have been neglected.

Bridge over the Moštěnka river
Kaut, Tomáš ; Čtvrtlík, Libor (referee) ; Panáček, Josef (advisor)
The content of the thesis is to solve the bridge over the Moštěnka river. It is a bridge with one field. 3 studies are designed, one of that was elaborated within the Framework of this thesis. Was selected option no. 2 concrete prefabricated T- beams with coupled concrete slab. The static´s models were created in SCIA Engineer 19.1 and IDEA StatiCa 10.1 and the reports were processed manuály, according to EC. The effects of wind, snow, acceleration and braking forces and slope of grade line have been neglected.
