Inspection and preliminary survey of the road bridge
Kocuba, Robert ; Heřmánková, Věra (referee) ; Cikrle, Petr (advisor)
This bachelor's thesis is dealing with inspection and preliminary survey of the bridge by performing the tests of concrete compressive strength on bores. In the theoretical part is performed the review of literature, documents and applicable standarts, focusing on bridge terminology, records of bridges, types of inspections, tests of bridge constructions and material, which was used on bridge constructions in the first half of twentieth century. In the practical part are evaluated the tests of concrete compressive strength on bores and tests of hardness. The result of this part is the condition assessment of the bridge, based on the inspection. For every part of the construction is assigned the strength class of the concrete, based on the tests. Also, the conceptual design, which relates to remediation of the chosen bridge construction, is processed.

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.

Survey and assessment of reinforced concrete bridge construction
Šnédar, Jaroslav ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
The aim of this thesis is to evaluate the real condition of reinforced concrete beam bridge located in Brno Jundrov. In order to evaluate this condition, there was made the main bridge inspection. Subsequently, a number of diagnostic methods were used, such as hardness tests, concrete stress strenght, ultrasonic pulse method, including their evaluation. In terms of the main inspection, the condition of construction of the bridge was evaluated as V - bad. We found out that the concrete from which the bridge is built of is in very good condition. The problem, however, is the condition of the reinforcement located on the bridge. Based on its condition there must be expected lifespan within the next 5-10 years.
