Design and performance diagnostics of building
Dušek, Erik ; Žítt, Petr (referee) ; Daněk, Petr (advisor)
The bachelor’s thesis deals with diagnostics of a reinforced concrete road bridge, evidential number 325-021 in Hostinné, Hradec Králové region. The goals are to design and partially execute a diagnostic examination. As a part of the thesis, there is a visual inspection of the bridge and survey of the existing design documentation. The conclusion is dedicated to evaluating the diagnostic results and outlining reconstruction.

Inspection of the implementation of reinforced concrete structures
Juráň, David ; Vymazal, Tomáš (referee) ; Cikrle, Petr (advisor)
This diploma thesis deals with the control of the implementation of reinforced concrete structures. The theoretical part deals with the issues of this theme. There are presented individual work processes of the implementation of reinforced concrete structures, accesses of valid standards, used diagnostic methods and also inspection and test plans for cast-in-place reinforced concrete structure. The practical part is divided into three chapters. The first chapter applies with the most frequent defects in new reinforced concrete structures and two remaining chapters with the inspection of newly built structures for which arose misgivings about the quality of execution.

Diagnostics in the case of evaluating of current state of a building
Kopec, Jan ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This work deals in the theoretical part in its theoretical part with a summary and detailed description of selected diagnostic methods that were applied to selected structural parts of an existing bridge structure within the practical part. The thesis also deals with the basic terminology and terminology in the field of bridge construction, subsequently, in its practical part deals in terms of diagnostics, the implementation of structural and static survey and subsequent evaluation of the current structural, technical and static state on selected structural units of existing reinforced concrete bridge structures

pH measurement
Žatečka, František ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
This bachelor thesis deals with principles of pH measurement with focus on measurements in concrete. The very beginning of the work describes basic principles of measurement. On those, basis a research of methods for measurements in concrete was done with priority on non-destructive methods. According to the theory a survey of Czech market was conducted. The last part of the work is description of experiments that are based on theory.

The Issue of testing shotcrete
Škapová, Pavla ; Hela,, Vlastimil (referee) ; Hubáček, Adam (advisor)
The master‘s thesis focuses on testing the shotcrete prepared in laboratory conditions. The main observed properties are compresive strenght of shotcrete and modulus of elasticity. The aim is assessment of methods for measuring those parameters. The calibrating correlations for strenght characteristics of shotcrete are given by obtaining the results of used methods. The shotcrete composition, amount and type of accelerating additive as well as economic aspect of using shotcrete is also assessed.

Assessment of the strength of concrete structures by a combination of non-destructive and destructive methods
Masařík, Dominik ; Kocáb, Dalibor (referee) ; Cikrle, Petr (advisor)
This bachelor's thesis is about a combination of destructive and non-destructive methods, including a description of the most modern devices of reflection hardness testers. Further on, an analysis of the new norm ČSN EN 13791 is performed. The practical part of the thesis is about measuring on concrete bodies using the latest rebound hardness tester SilverSchmidt, ultrasonic pulse method and tests of compressive strenght of concrete on individual bodies. The evaluation took place on the base of established linear and quadratic regressions on the test specimens. In situ compressive strength was deternibed according to the procedures specified in the ČSN EN 13791 standard.

Application of non-destructive methods determining the quality of glued wood bondlines
Dvořáková, Martina ; Brožovský, Jiří (referee) ; Vaněrek, Jan (advisor)
The presented bachelor thesis is focused on the evaluation of timber elements by using non-destructive methods which are intended for the evaluation of glue lines. The main part of the work is focused on summarizing and the detailed description of selected non-destructive methods which can be used for glue line evaluation. There is also carried out the researche of selected scientific articles describing the application of non-destructive methods with regard to the evaluation of timber elements.

Building survey and evaluating the state of construction
Broďák, Marek ; Komárková, Tereza (referee) ; Heřmánková, Věra (advisor)
This diploma thesis is focused on building survey and evaluating the state of existing constructions. In theoretical part are described the process of evaluating the state of existing constructions and selected diagnostic methods. The practical part is dealing with performed structural and technical survey of industrial object including evaluation of the strength of concrete and verification of the reinforcement. The last part is focused on a static assessment of selected supporting element of the structure.

Assessment of the state of wood in the construction and evaluation of the usefulness of non-destructive testing methods
Munduchová, Markéta ; Vaněrek, Jan (referee) ; Brožovský, Jiří (advisor)
This bachelor's thesis consists of theoretical and experimental part. In the theoretical part there are given findings regarding on structure of wood, its basic properties and durability. The following describes the wood defects, influence of wood pests and fungi, types of wooden structures, climatic conditions, chemical corrosion and mechanical damage to the wood. Evaluation of the status of wood in the structures is appropriate by using non-destructive methods, therefore was performed research articles on these methods. Non-destructive methods are used: visual, hardness tests, electrical, radiation, optical and moisture determination. Experimental part of the bachelor's thesis is focused on ultrasonic impulse method, that can detect defects or damage in the wood mass that depends on the speed of ultrasonic impulse. For a reliable interpretation of the results it is appropriate to combine non-destructive methods when assessing status of wood structure.
