Survey and Diagnostics of Building Construction
Slavětínský, Šimon ; Cikrle, Petr (referee) ; Anton, Ondřej (advisor)
The subject of this final thesis is the diagnostic survey of the prefabricated hall made of framed concrete in the areal of Fatra Chropyně. The thesis contains description of construction and technological survey and diagnostic methods. The practical part contains material assessing of chosen elements of construction (beam, column,precast floor slab). It is also focused on localization of position and diameter of reinforcement. Last step is focused on quality of the concrete, particularly compressive strength and strenght class of concrete.

The Architectural and Engineering Research of the Building Construction
Blaha, Jaroslav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The subject of this bachelor thesis is the diagnostic survey of the industry prefabricated hall. The thesis contains options of reinforced concrete diagnostic. Consequential conclusion judges material characteristics of the beam and roof girder.This thesis is focused on localizing the position and average of reinforcement in every single element. Next step is focused on quality of the concrete, particularly compressive strength and modulus of elasticity. The modern machines, like Hilti PS 1000 and Profometer PM-630, are used to localize the position and diameter of reinforcement. The quality of concrete is determined by removed bore core. Evaluation of material characteristics of the structure is in the conclusion.

Preparation and implementation of construction and technical survey of a building
Šebela, Václav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
This bachelors thesis covers preparation and implementation of a construction and technical survey of reinforced concrete structure in Rousínov. The theoretical part is describing examined properties of reinforced concrete and methods of diagnostics used in this field of study. The practical part focuses on the construction and technical survey. The main focus of the survey is the quality of concrete and the assessment of reinforcement in representative parts of the structure. The last part concludes results of the survey.

Diagnostics of ceiling structures - possibilities of using GPR
Resl, Jaroslav ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
The thesis is focused on the overview of the diagnostic methods for engineering surveys. The distribution of ceiling structures according to various parameters is described. The theoretical part then provides an analysis of diagnostic methods for the ceiling structures in more detail. It includes a description of the operating principles of GPR. The practical part explains the construction and technical survey of ceiling structures using ground penetrating radar as well as measuring on a physical model. Practical measurement is focused on the use and limitations of the radar.

Pulse Generator for GPR
Martínek, Luděk ; Dušek, Martin (referee) ; Šebesta, Jiří (advisor)
This thesis deals with the question of ground penetrating radar. At first it considers the electromagnetic field and its mathematical description. Then it covers measurement of electromagnetic pulses and their processing of sub-surface ground penetrating radar. . In this thesis is also described the involvement of pulse generator with several transistors operating in avalanche breakdown. Individual transistors are compared in time domain. The received waveform is then selected the best transistor for the final generator. Then is proposed solution for the final pulse generator and its implementation. For impulsive generator is also designed and constructed increasing the DC-DC voltage converter. Finally, it is necessary to measure the time behavior of the output pulse generator.

Survey and Diagnostics of Building Construction
Bernard, Lukáš ; Heřmánková, Věra (referee) ; Anton, Ondřej (advisor)
This thesis deals with a diagnostic survey of a reinforced concrete frame. The first part of the thesis focuses on the properties of the reinforced concrete as well as on the detection of the reinforced concrete’s properties using selected non-destructive methods, semi-destructive methods and destructive methods. The second part of the thesis, which is closely related to the first part, focuses on detection of piles’ and beams’ reinforcement using an electromagnetic indicator Profometer PM-630, Ground-penetrating radar Hilti PS 1000 and chopped probes. It also focuses on determining the compressive strength of the concrete using the ultrasonic impulse method of the Pundit PL-200 machine. The results are further specified by the cores description.

Survey and Diagnostics of Building Construction
Růžička, Petr ; Láník, Jaromír (referee) ; Anton, Ondřej (advisor)
This master's thesis deals with the preparation, execution, and evaluation of a structural and technical survey of the former football stadium za Lužánkami in Brno. The theoretical part focuses on diagnostic methods relevant to the survey of reinforced concrete constructions. The practical part describes suggestions for the survey, and the execution of each of its parts, followed by a structural evaluation of the chosen component. At the end, an evaluation of the state of the building is carried out based on the results of the survey and calculations.

Preliminary survey of the historic reinforced concrete bridge
Ježíková, Pavlína ; Žítt, Petr (referee) ; Cikrle, Petr (advisor)
This bachelor thesis focuses on the preliminary survey of a bridge connecting the west and east wing of the Veveří castle. It is a structure of a very high significance because it is presumably the oldest preserved bridge made from reinforced concrete, it was completed in 1898. A visual inspection of the outside and inside parts of the bridge was performed. To examine the quality of used concrete and type reinforcement and finding out the condition of the structure, destructive and non-destructive diagnostic tests were used. Because of the historical significance of the bridge is part of the thesis devoted to the history of bridge construction and the author of the Veveří Bridge and the pioneer of reinforced concrete constructions in our country professor Josef Melan.

Possibilities of using GPR in diagnostics of bridges
Moravská, Veronika ; Vítek, Lubomír (referee) ; Anton, Ondřej (advisor)
This bachelor thesis deals with the diagnostic survey of reinforced concrete bridges using GPR. In the first part of the GPR specified nomenclature, physical concepts. The next chapter deals with methods of diagnosis, which are used to locate reinforcement. The next section describes the basic types of bridges, bridge terminology and reinforcement of the main body. The practical part describes the diagnostic surveys of existing bridges.

Survey and Evaluation of Reinforced Concrete Structure
Ježíková, Pavlína ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This diploma thesis focuses on the construction survey of the building where the University Cinema Scala and the Bolek Polívka theatre is located. The building will celebrate its 100th birthday in 2028 and its author is the builder Jaroslav Josef Polívka. The survey concerns reinforced frame constructions. The compressive strength of concrete cores and type of reinforcement was determined and non-destructive and destructive diagnostic tests were used. The first aim of the survey was to collect materials for a static report due to the planned superstructure but a visual inspection of the construction was performed and serious failures were found. For these reasons, the closure of the building was necessary. Last part of the thesis is the design of the reinforcement, if the same structure was designed according to the currently valid Eurocodes, but with the use of original materials; as well as a comparison of the designed reinforcement with the actual reinforcement.
