Diagnostics and assessment of prefabricated reinforced concrete structures
Kocuba, Robert ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This thesis deals with inspection and constructionally technical research of reinforced concrete prefabricated construction from the second half of 20th century. In theoretical part, the research of literature, documents and valid standards is performed, with a focus on production and construction of prefabricated elements and also on the metodology of research. In practical part, the detection of reinforcement of individual elements of the construction and concrete properties is performed. The result of this work is the assessment of the state of the construction, static calculation of the ceiling panel and idea proposal for eventual reconstruction.

Survey and Diagnostics of Reinforced Concrete Structure
Bernard, Lukáš ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
This diploma thesis deals with construction and technological survey of the reinforced concrete structure. The first part of the diploma thesis deals with the properties of the reinforced concrete and with the building survey methods applied in the second part of the thesis. The second part of the diploma thesis focuses on diagnostics of existing structure. More specifically, the hardness of the concrete is tested using a Schmidt hammer and then it is further specified by testing the cores. The reinforcement in the reinforced concrete is also tested using electromagnetic indicator, ground-penetrating radar, and chopped probes. Lastly, a static assessment of the selected girder and column is conducted.

Survey and Diagnostics of Building Construction
Pernová, Jana ; Komárková, Tereza (referee) ; Anton, Ondřej (advisor)
The object of the theoretical part of this diploma thesis is overview of the historical development of reinforced concrete and concrete reinforcements, including the elaboration of a detailed methodology for the assessment of the state of bridge structures. It is applied in practical parts of two bridges independent on each other. There are used the most modern technologies like device Hilti PS1000, profometer PM-630 to diagnose objects and they are completed by chopped probe. It also includes a structural analysis of the load capacity, that concurrently evaluates the quality of the construction.

Application of GPR method for detection of structural failures
Křepelka, Jan ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This Bachelor thesis deals with the non-destructive testing, which enable researches of failures in concrete inner structure. In the theoretical part of the thesis, selected methods are described based on their principles. Specific possibilities of use, abilities and limits are based on the method’s principle. In the practical part, the thesis focuses on Ground Penetrating Radar with the usage of a new multi-frequency scanning technology. The measurements took place with commonly used Ground Penetrating Radar Hilti PS 1000 X Scan and also with newly available Ground Penetrating Radar Proceq GPR Live. Not only the measurement results of model solids were compared, but also of real bridge construction.

Survey and Diagnostics of Building Construction
Šebela, Václav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The diploma thesis deals with the implementation and preparation of a structural and technical survey of the former football stadium Za Lužánkami in Brno. The theoretical part discusses the specific diagnostic methods used. The practical part describes in detail the individual parts of the survey and its evaluation. The aim of the survey was to determine the current state of the structure. Finally, the results of the survey are evaluated.

Diagnostic methods for reinforced concrete bridges
Vaňková, Michaela ; Vítek, Lubomír (referee) ; Anton, Ondřej (advisor)
This bachelor thesis deals with the diagnostic survey of reinforced concrete bridges. In the introductory part is the bridge terminology, another part deals with methods of diagnosis,which can be applied to concrete bridges. Last chapter refers to the typical defects and disorders of reinforced concrete bridges. The practical part describes the technical survey of existing bridge and comparison methods determining the position of reinforcement - a radiometric method and using the GPR.

Survey and Diagnostics of Building Construction
Resl, Jaroslav ; Cikrle, Petr (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the overview of the diagnostic methods for engineering surveys reinforced concrete constructions. The practical part explains engineering surveys of industrial building, evaluation of concrete strength on existing building and results from search reinforcements on individual elements. Next part is focused on load testing precast floor slab removed from construction and evaluation load capacity. The last part include structural design of elected parts (precast floor slab and beam).

Survey and Diagnostics of Building Construction
Řezáč, David ; Komárková, Tereza (referee) ; Anton, Ondřej (advisor)
The subject of this bachelor thesis is the construction research and diagnostics of the construction with the focus on the verification of the prestressing reinforcement of the prefabricated prestressed bridge. The theoretical part of the thesis focuses on reinforced concrete, prestressed concrete, their properties and determination of these properties by means of instruments of selected non-destructive, semi-destructive and destructive methods. In connection with the theoretical part, the most suitable methods were used to verify the position of prestressing reinforcement, which means using the Hilti PS1000 georadar and the electromagnetic indicator Profometr PM-630.

Methods for the survey reinforced concrete bridges
Ehrenberger, Ondřej ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
Policies and types of diagnostic examination of a bridge. The theoretical section contains review diagnostic methods for a steel concrete frameworks. In a practical section there is made a examination of a bridge object over a river Moravia and a suggestion of the examination according to the detected defects. In the experimental section we are discovering, with a help of georadar, a location of reinforcement of a monolithic wall and board.
