Diagnosis selected bridge structure
Novák, Jakub ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
The Diploma thesis deals with the Diagnostics of Reinforced Concrete Bridge in the village of Luhačovice. This thesis also describes the individual Diagnostic methods and instruments used in purpose to make Diagnosis of bridge constructions. The main aim of the Diagnostics is to determine the current state of the Bridge which consists in verification of the actual road structure, determination of the physical and mechanical parameters of the Concrete (strength, depth of carbonation) and in some parts of the bridge structure to determine the type, number and position of the bending or shear reinforcement. Based on the evaluation of the laboratory tests a static calculation of the selected part of the Bridge structure is performed. The final evaluation is the determination of the load and the subsequent design of the necessary and recommended measures for maintaining or improving the functionality of the bridge structure.

Overpass bridge across the highway
Černý, Pavel ; Šopík,, Leonard (referee) ; Nečas, Radim (advisor)
The topic of this thesis is detailed design of the supporting structure of a bridge. Three variants are designed. The structure is designed as a single beam bridge of 6 spans. The calculation of load efects make in software MidasCivil 2019 and Scia Engineer 18.1. The subject of the expertise of the structure is service limit state and ultimate limit state. For evaluation of cross sections is used MS Excel. Both design and relevant drawing documentation of the bridge deck and substructure. The design and assessment are according to the europien standards.

Design of the single span bridge in the town Uherský Brod
Kutálek, Jiří ; Svoboda, Adam (referee) ; Klusáček, Ladislav (advisor)
The bachelor thesis aims to design a new version of the loadbearing structure for the existing bridge structure. The design was processed in two options, from which the beam solution superstructure with short cantilevers for catching at-rest earth pressure was chosen. The design and the assessment of the structure were made according to valid EN standards. Structural design was made by hand(-done) calculation with the assistance of SCIA Engineer 18.1 software. The thesis includes drawings and visualizations of the new loadbearing structure.

Design of a one-span beam bridge
Podškubka, Patrik ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The aim of the work is to design a new safe and economical bridge construction, over the existing communication, category S7,5, according to currently valid standards and regulations. Out of the three proposed variants was chosen the variant of a prestressed one-span bridge with two beams and a length of 26,750m. The category of the transferred communication is S7,5.

Railway bridge across the river Svitava
Findura, David ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
This thesis deals with a design of an one-track railway bridge over the river Svitava. Out of three proposed variants was chosen as the most economical and feasible the variant number 2 - two-beam prestressed bridge with one span. According to actual EN standards the construction was designed and assessed to the serviceability limit state and the ultimate limit state.

Design of a one-span beam bridge
Fojtů, Jan ; Panáček, Josef (referee) ; Nečas, Radim (advisor)
The aim of the thesis is a safe and economical design of a bridge over a watercourse according to all valid regulations and standards. There were designed three possible options in accordance with the recommended dimensions. The variation with the cross-section that consists of two beams and effective width of flanges is preferred. The thesis is mainly focused on the design of bearing concrete structure.

Road beam bridge
Prekop, Michal ; Pěkník, Robin (referee) ; Koláček, Jan (advisor)
The subject of this bachelor´s thesis is the desing of prestressed beam bridge. Three preliminary studies have been proposed and one of them was selected for more detailed processing. Span length of construction is 30,0 m. Selected variant was assessed for serviceability limit state and ultimate limit state according to the recent European standards. The thesis is mainly focused on the desing of bearing concrete structure.

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.

The assessment of the existing beam bridge in town Valtice
Zatloukal, Lukáš ; Nečas, Radim (referee) ; Klusáček, Ladislav (advisor)
This bachelor thesis deals with assessment of beam bridge´s construction. The content of work is to create bar, frame model of construction in computational program. Calculate load on individual bars of model and set it on critical places of construction in order to maximum bending moments. By the analysis of internal forces from outputs of computational program and bending load capacities of cross section, determine maximum possible random of load which is construction able to transmit in the present state.

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.
