Structure diagnostics in relation to the current condition assessment
Pospíšil, Ondřej ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
Bachelor’s thesis is concerned with the construction diagnosis methods used for assessing existing reinforced concrete constructions. In the practical part of the thesis, the methods mentioned are apllied for a technical reconnaisance of the facility in the sports and recreational compound Kraví Hora in Brno, which is supposed to be reconstructed early. The diagnosis process results are interpreted in the summary of the thesis.

Influence of dispersed reinforcement on the physico-mechanical properties of the resulting composite
Láník, Jaromír ; Adámek, Jiří (referee) ; Kolář,, Karel (referee) ; Doc.Ing. Karel Kubečka, Ph.D (referee) ; Schmid, Pavel (advisor)
The dissertation is focused on the issue of implementation and evaluation of the laboratory tests fiber reinforced concrete. The issue of steel fiber is solved in terms of their physico-mechanical parameters, which are an important part of their design and reliable operation in the product design. The experimental part of the thesis is focused on laboratory tests of steel fiber of different strength classes and different weight benefits of steel fibers, the default reference mixture of plain concrete are certified mixtures commonly used as structural concrete in construction. The evaluation of the testing of samples produced steel fiber is made by three selected recommending regulations for the design and testing of structural steel fiber. In conclusion, the individual obtained experimental results are compared.

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.

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

Evaluation of a historically valuable reinforced concrete structure
Uchytilová, Jitka ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
In the theoretical chapters of the bachelor thesis is summary of the historical development of reinforced concrete construction, including individual components of concrete. Furthermore, the issue of the evaluation of historically valuable structures and used diagnostic methods is processed. In the practical chapter there is a diagnostic survey of the selected historical structure including the conceptual design of rescue.

Bearing capacity of the ceiling structure made by diagnostics and load test
Candra, Lukáš ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This bachelor thesis deals with diagnostics and static loading test of floor structures. The thesis shortly described construction systems floor structures, the theory of preparation and method of their diagnosis. The selected diagnostic methods are more fully analyzed and described. Furthermore, the work deals with specific floor structure, which is implemented diagnostics, the load test, static calculation and final design evalution.

Technical conditions of the existing object
Voltr, Vojtěch ; Láník, Jaromír (referee) ; Schmid, Pavel (advisor)
This bachelor thesis deals with construction and technical research and design of diagnostic methods. In the practical part are this diagnostic methods applicated to preliminary and detail research of existing object of old restaurant in village Velichovky. Output of this paper is a list of the necessarily works to get this building in use.

Experimental and numerical analysis of reinforced concrete elements
Niedoba, Jakub ; Láník, Jaromír (referee) ; Žítt, Petr (advisor)
This master‘s thesis deals with the behaviour of strengthened reinforced concrete beams. The aim was to evaluate different types of strengthening in comparison not only with each other, but also with the reference beam. Three reinforced concrete beams were fabricated for the purpose of the thesis. The first served as a reference beam, the second was strengthened with carbon lamella glued to the lower edge of the reinforced concrete beam, and the last one was strengthened with unbonded post-tensioning system. Subsequently, they were all loaded by a four-point bending. An evaluation was then carried out which shows that the two strengthened reinforced concreate beams resist the load much better than the reference beam. In the conclusion, different utilization possibilities of both methods are listed, as well as the disadvantages that must be taken into account when designing.
