Diagnostics of Reinforced Concrete Bridge
Rozbroj, Lukáš ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This thesis contains diagnostics of a reinforced concrete girder bridge in the municipality of Újezd u Brna. The aim is to conduct an inspection of the bridge, gather quality photo-documentation of defects and failures and design and conduct a diagnostic examination of such extent that would be necessary for judging the load bearing capacity of the bridge. The result of this thesis is the determined load bearing capacity and a proposal of measures required to keep the bridge functional.

Reconstruction of a beam bridge
Otevřel, Rostislav ; Klusáček,, Ladislav (referee) ; Nečas, Radim (advisor)
The work deals with the calculation of current carrying capacity of the bridge girder structure according to ČSN 73 6222 and the proposal for a new bridge. The bridge is used to transfer local roads across the river Svratka. The bridge is designed as a plate full cross-section, simply placed with a length of 13,174 m. The communication category is S 7.5. Loads and assessment are done according to Eurocode.

Reconstruction of the road bridge near the village Holýšov
Svoboda, Adam ; Pinkas, Karel (referee) ; Klusáček, Ladislav (advisor)
The thesis deals with design of strengthening of existing bridge structure near the village Holýšov using modern method of additional presstresing. The bridge over the river of Radbuza is h-shaped beam bridge, which was built in 1924. In the present state its load capacity is under the limits for bridges situated on first-class roads. Original documentation of the bridge does not exist, the main source of information about construction details is the diagnostics research. The method of reinforcement by post-tensioning by cables in substituted cable ducts is highly efective in terms of the incerease the load capacity of existing bridge structure. The design of strengthening and the final load capacity was verified by static calculation.

Probabilistic analysis of reinforced concrete bridge made of I-73 girders
Nezval, Michal ; Šomodíková, Martina (referee) ; Lehký, David (advisor)
Many older bridges on the highways and roads in the Czech republic and all arend the world have been designed by codes, which are distinct of currently valid codes. Considering current codes, it is possible to set load bearing capacity in few different ways. In presented diploma thesis nonlinear finite element analysis using deterministic methods is compared with fully probabilistic nonlinear finite element analysis. Girder I-73 is analysed. Also the influence of degradation processes and following corrosion of reinforcement is taken into account, when load capacity is predicted for residual service life.

Diagnostics of reinforced concrete structures
Nápravník, Petr ; Komárková, Tereza (referee) ; Láník, Jaromír (advisor)
This thesis deals with the structural-technical survey of beam bridge no. 204c - M1, located in Bystřice pod Hostýnem. The theoretical part of the thesis is devoted to general characteristics of bridges, load capacity of bridges, beam bridges, concrete reinforcement, concrete, diagnosis of reinforced concrete structures, and laboratory evaluation. The practical part deals with carrying out a structural-technical survey on the bridge mentioned above, its evaluation and assessment, recalculation of the load capacity, and design of the necessary rehabilitation to maintain the functionality of the bridge.
