Use of ultrasound testing of concrete in bridge structures
Olejková, Sabina ; Komárková, Tereza (referee) ; Cikrle, Petr (advisor)
There are analyze kinds of diagnostic methods in terms of bachelor’s thesis. It is written about principles of ultrasonic pulse method and its options of usage on the current concrete structure. There are processed results of measurement on the testing samples which will be compared with results of stress strength. There is also spoken about calibration relationships in the bachelor’s thesis. Calibration relationships are described in Czech technical norms.

Diagnosis of the fire damaged bridge
Olejková, Sabina ; Láník, Jaromír (referee) ; Cikrle, Petr (advisor)
This thesis is about assessment of a bridge construction influenced by fire accident. The bridge is situated at the highway D46 beyond the town Držovice. Within this construction research, there will be mentioned diagnostic methods – A non- destructive method (Ultrasonic pulse method and hardness tests) and destructive methods (borehole and tear off tests). For find out in which way was the concrete of the bridge damaged and hurt while facing a high temperature of fire, there were taken samples, which were analyzed by physical and chemical test. We can analyze composition and microstructure of the concrete. The result of this tests will be evaluated, and the actions of a remediation will be suggested.

Use of Non-Destructive Methods and Regression Equation in Diagnostics of Building
Olejková, Sabina ; Hrabová, Kristýna ; Masařík, Dominik
Due to the increasing number of reconstructions of historic buildings in recent years, the importance of more enviromentally friendly non-destructive methods is also growing. In the future, it would be appropriate to establish relationship or compare the results of non-destructive tests and destructive tests. This relationship would determine the degree of risk (constant or deviation) if only destructive methods were chosen in the diagnosis of building structures. This could mean a major shift in non-destructive testing. If would be both a more enviromentally friendly variant of testing building structures with regard to the enviroment.
