20.500.12556/DKUM-44561 PRIMERJAVA RAZLIČNIH METOD OJAČITVE TANKIH BETONSKIH ELEMENTOV S KONTINUIRANIMI OGLJIKOVIMI VLAKNI COMPARISON OF VARIOUS STRENGTHENING METHODS FOR THIN CONCRETE MEMBERS USING CONTINUOUS CARBON FIBRES V diplomskem delu smo obravnavali in primerjali različne metode ojačitve tankih betonskih elementov z ogljikovimi vlakni. V teoretičnem delu smo predstavili lastnosti uporabljenih materialov in opisali različne načine ojačitve betonskih elementov. V eksperimentalnem delu smo opisali postopek priprave vzorcev in izvedbo štiri točkovnega upogibnega preizkusa. Primerjavo rezultatov smo nato izdelali med tremi različnimi načini ojačitve na vzorcih enakih dimenzij in ojačanih z enako količino ogljikovih vlaken. Rezultati preizkusov so pokazali, da zunanje ojačani vzorci dosegajo višje upogibne trdnosti kot vzorci ojačani v sredini prereza. In the diploma thesis, we discuss and compare different methods of thin concrete members reinforcement with carbon fiber. In the theoretical part we present the properties of the materials used and describe the different ways of reinforcing concrete members. In the experimental part we describe the process of preparing samples and implementation of four-point bending test. Comparison of the results was then made between three different models of reinforcement on the samples of the same dimensions and reinforced with the same amount of carbon fiber. The test results showed that the external bonded reinforced members have higher flexural strength than the samples reinforced in the middle of the cross-section. tanki betonski elementi ojačitve ogljikova vlakna štiri točkovni upogibni preizkus thin concrete members reinforcement carbon fiber four- point bending test true true false [R.
