Survey and Diagnostics of Building Construction
Haloun, Jan ; Cikrle, Petr (referee) ; Anton, Ondřej (advisor)
The topic of the first part of this bachelor thesis covers the methods of diagnostics of reinforced concrete constructions and their practical application. In the theoretical part are described the methods currently used with diagnostics of reinforced concrete constructions with focus on methods used in practical part. The practical part covers the survey of reinforced concrete constructions and its evaluation. The main objects of the practical part were the detection of the strength class of concrete and real reinforcement of certain elements.

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 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

Diagnostics methodology of historical brickwork
Bakešová, Martina ; Cikrle, Petr (referee) ; Anton, Ondřej (advisor)
The aim of my bachelor’s thesis is to carry out historical overview of progress of masonry building elements and structures, including their thorough methodology of diagnostics. The introduction text is considering historical progress of masonry elements in Czech Republic and abroad. As following are described brick manufacturing methods of present and past, which is closely related to the progress of brick dimensions and its visual appearance. On sample specimen can be observed mentioned progress in the visual appearance, mechanical properties and so on. The diagnostics of masonry structures is realised via particular tests described in the thesis. Important tests used for overall evaluation are determining brick dimensions, it is volume density, absorption, compressive strength determined via destructive and non destructive methods. Also flexural tensile strength and compressive strength of the mortar. Output of my thesis is overall evaluation of all parts mentioned above.

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.

Verification of the usability ultrasonic pulse method for the assessing of frost resistance of concrete bricks
Kašparová, Jana ; Hubáček, Adam (referee) ; Brožovský, Jiří (advisor)
Purpose of Bachelor thesis is to verify use of the utrasonic impulsive method to determine frost resistence of the concrete. Theoretical part disscusses about basic characteristic of a vibropressed concrete, description of a causes of frost and defrosting on the concrete. As well further factor simple menting frost resistance are reviewed. Summary is followed with standard requirements forwall concrete elements, trial proceduresfor non destructive and destructive methods for concrete and other construction materials and thein evaluation systems. Second part of Bachelor thesis is dedicated to analyse and evaluate results and relationship of trials used for testing of a concrete brick in frost resistence with use of cyclic freezing and use of a trial non destrucive ultrasonic impulsive method as well destructive mode.

Operative diagnostics of an object affected by fire
Hnátková, Barbora ; Lisztwan, Dominik (referee) ; Schmid, Pavel (advisor)
This bachelor’s thesis deals with technical construction research of the family house which was affected by a fire. The theoretical part of this bachelor’s thesis is describing a fire resistence of the masonry and mainly timber structures. In the practical part is a description of the construction, descriptions of the diagnostic methods, goings of the tests and their evaluation. The main focus of the survey is to find out a state of the construction after the fire and its reliability.

Survey of Reinforced Concrete Structure
Masařík, Dominik ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
The thesis deals with the investigation of reinforced concrete structure. The theoretical part is devoted to the general procedures for the evaluation of the existing structure. Then the methods used in the practical part of the survey are described, including state-of-the-art measuring instruments. The part focuses on the standard EN 13 791, which introduces new procedures for the evaluation of the compressive strength of a structure. The practical part deals with the investigation of a reinforced concrete beam floor supported by vertical brick piers. Due to the overloading of the new technology, the beam ceiling is assessed to see if it can accommodate the specified loads from the new equipment. The sampling of the test bodies, determination of the concrete properties, determination of the reinforcement of the individual elements and subsequent loading to the strength class are described. Also included is an evaluation of the characteristic strength of the masonry elements and the subsequent design of the structure.
