Quantification and improvement in bridge precision measurement deflection
Hvozdenský, Petr ; Suza, Patrik (referee) ; Pernikář, Jiří (advisor)
This thesis deal with improvement in bridge precision measurment deflection for Mostní a silniční Ltd. Its goal is through analysis of process of measurment and factor location, which have fundamental influence on measurment precision. First, theoretic part, represents the company, formulates problems and goals of thesis, history of bridges, world disasters, sort of bridges measurments, bridges evaluation and questions of giant transportation. In second, practical part, problems with measurment and its evaluation are described. Results are evaluated and corrective measures and recommendation are proposed in the final part.

Diagnostics and assessment of the structure of bridge
Lehocký, Peter ; Komárková, Tereza (referee) ; Kocáb, Dalibor (advisor)
This diploma thesis focuses on diagnostics of bridge structures. First part of this diploma thesis will focus on theoretical knowledge about bridge structures and common diagnostic techniques suited for examining material priperties of samples taken from structure. Second part of this thesis will focus on practical use of experiments used in diagnostic branch. I will be doing visual observation of concrete structure followed by experiments on core samples. End of thesis will be evaluating structure from global perspective and will deliver specific sugestions for renovation.

Highway bridge over deep wally
Pírková, Barbora ; Rušar, Jaromír (referee) ; Klusáček, Ladislav (advisor)
The subject of this diploma thesis is the design and the assessment of post-tensioned bridge structure over deep wally, which transfer road D26,5/100 on D1 in Slovakia between Hubová – Ivachnová. Three variants were designed and compared. The most suitable variant of two identical bridges with box cross-section and constant height was further assess in detail.

Deformation Surveying of Bridge Construction and Railway Track
Staněk, Boleslav ; Bureš, Jiří (referee) ; Švábenský, Otakar (advisor)
This diploma thesis deals with the phases measuring deformation of the bridge construction and railway superstructure on the bridge over the river Dyje in Breclav and its surroundings. The main goal was to determine the longitudinal displacements of the rail web and the bridge structure. The object of this thesis was also transverse displacements which have been caused mainly due to temperature changes. The introduction describes the location. The following section discusses the methodology terrestrial deformation measurements and calibrations selected surveying devices. Furthermore, there is stated the processing of measurements and the calculations. In conclusion, the thesis evaluates the longitudinal and transverse displacements, which are shown in the annexes.

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.

Evaluation of the current condition of the bridge structure
Urbánek, Filip ; Hrabová, Kristýna (referee) ; Láník, Jaromír (advisor)
The diploma thesis deals with the execution and evaluation of a structural and technical survey of a reinforced concrete bridge structure from 1923. The second objective of the thesis is to calculate the load-bearing capacity of the structure with regard to the results of the tests carried out. The theoretical part briefly describes the history of bridge construction, the methodology of bridge inspections and methods of diagnostic survey. In the practical part, in situ tests are carried out with subsequent laboratory evaluation and calculation of the necessary parameters. The geometric and material parameters of the structure were used as a basis for the creation of a structural model. The normal, exceptional and exclusive load capacities were recalculated and the necessary repairs and rehabilitation were proposed with regard to the observed condition of the bridge structure.

Relocation of roads II / 431 and III / 4317 near the village of Kojátky
Janko, Vojtěch ; Loučka, Miroslav (referee) ; Matuszková, Radka (advisor)
The aim of this thesis is the relocation of roads II/431 and III/4317 near Kojátky village. This is due to the unsuitable layout of current routes which were poorly arranged because of too many horizontal and vertical curves with small radius. Another reason was a bad technical state of bridge structures, one of them was in serious disrepair. The project deals with the relocation of current roads to more suitable routes including the option allowing access to the nearby estates and the connection to the existing cart tracks. The project also addresses two bridge structures across the streams.

HST Station at the Airport Brno Tuřany
Svobodová, Lenka ; Kyselka,, Mojmír (referee) ; Nový, Alois (advisor)
Main topic of this Masters Thesis is design of railway station for high speed line railway. Building site is situated in East Moravian region in the district of Brno-Tuřany. The building is designed as a detached two-storey object standing on the bridge over the railway. Mass of the building consists of two trimmed blocks which are mutually mirrored. The mass of both parts of the building is pervaded by illuminating stripe. Its shape is also based on the shape of trimmed block and rises over the surrounding surfaces. There are placed vertical paths in the stripes. It helps passengers in orientation because these are visible even from the outside of the building. This arrangement of individual masses symbolizes both direction of the arrival of trains to the station. There is placed arrival and departure hall in the middle of the object. Its height is similar to the height of the object itself. The hall is surrounded by the service facilities of the railway station situated on two floors. The supporting structure is made of steel. Both peripheral housing and roof are supported by the frame construction consisting of planar lattice beams. Construction of the façade is composed of frame system Wicona. The peripheral housing is tiled with panels of expanded metal.
