Bridge over a highway
Vaculíková, Klára ; Pachl, Radek (referee) ; Panáček, Josef (advisor)
The diploma thesis describes the design of curved, pre-stressed concrete bridge over the highway D1. A variant, that is chosen for detail analysis, is a spine girder construction as a continuous beam with 3 spans. The thesis solves the construction to limit states according to applicable European standards (Eurocodes). There are developed clear and detailed drawings and visualization of the bridge.

Design of floating concrete structure
Páleník, Branislav ; Kolenčík, Pavel (referee) ; Zich, Miloš (advisor)
The project aimed to familiarize yourself with the issue of floating structures, according to the procurement documents and knowledge acquired during studie, a study of existing floating structures. Review was conducted design adapted from documents. More space was devoted bottom structure in the assessment. Other structures designed only provisionally.

Prestressed bridge No. 209 over the expressway R2 in Slovakia
Mareček, Tomáš ; Formánek, Ing Martin (referee) ; Koláček, Jan (advisor)
This thesis deals with a design of the bridge for second class highway S7,5 through speedway R2 in Slovakia. From the three proposed versions the version with unicameral structure was chosen for further detailed analysis. The longitudinal direction of the structure is designed as continuous three fields. The lenght of the spans is 23,1 + 33,0 + 23,1 m. Detailed design of the selected version of the structure of prestressed concrete bridge is processed according to limiting conditions, including consideration of the impact of the progressive construction of the bridge. It is elaborated a detailed structural analysis including drawings and visualization.

Prestressed bridge in Velké Pavlovice
Stloukal, Radim ; Růžička, Stanislav (referee) ; Koláček, Jan (advisor)
The subject of this thesis is to design a bridge construction over the river Trkmanka in the municipality Velké Pavlovice. The superstructure is designed as a prestressed one field slab bridge with the length of 16,85m. As a part of this thesis there is enclosed structural analysis calculated accordingly to ČSN EN 1992-1-1. The load effects were calculated by Scia Engineer and compared with manual calculation. The rest of the calculations are done manually and ocassionally compared to engineering software. The construction has been analysed for the ultimate limit state, serviceability limit state and the stress anchors have been designed.

Bridge on a highway
Knotek, Jan ; Nečas, Radim (referee) ; Panáček, Josef (advisor)
Subject of this bachelor’s thesis is design of new slab bridge construction over the II/464 road between the villages Příbor and Bílovec. The bridge converts highway D47. Thesis includes three studies. Pre-stressed rectangular cross-section slab with elliptical exterior trim, pre-stressed plate- grinder construction and construction of prefabricated beams and monolithic slab. For next assessment was chosen option no.1. Load effects calculation is solved in SCIA engineer 16.1. Design and assessment of the structure are made according to valid standards and regulations.

One span frame bridge
Buk, Petr ; Zich, Miloš (referee) ; Nečas, Radim (advisor)
The subject of this bachelor thesis is design of road bridge across the river. From the developed variants, one was selected. Selected variant deals with one span frame bridge. Construction is made of panel with run-ups from prestressed reinforced concrete. Bridge is designed perpendicular, with span range of 25,0 m. For the calculation of internal forces two computing models (rod and panel model) were made in SCIA Engineer 2018 program. Thesis deals with comparisons of internal forces in rod and panel model and comparison of short-term losses with SCIA Engineer 2018 program. Design and assesment of ultimate limit state and ultimate serviceability state was conducted in accordance with applicable standarts and regulations.

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 river after its widening
Strouhalová, Petra ; Rušar, Jaromír (referee) ; Klusáček, Ladislav (advisor)
This final thesis deals with new design of post-tensioned concrete bridge across river Vsetínská Bečva in the area Ústí u Vsetína. The existing bridge with three spans found in therms of inundation, that´s why is replaced by new four spans bridge construction. The bridge is situated on highway I/57 and used to transfer across the river. The superstructure is designed in three alternatives. Detailed assessment is only for one chosen variant a post-tensioned two-beam concrete.

Static analysis of residential building
Hanzlík, Petr ; Šopík, Leonard (referee) ; Zich, Miloš (advisor)
The discussion of the master’s thesis is static analysis of residental building. The thesis details the original solution from assesment and a new design variant solution. The work is focused on static solution of monolithic concrete plate with ribs and is devoted to limit states assessment of the plate with ribs. The thesis includes a time analysis structure and prestressed ribs in the new variant.
