20.500.12556/DiRROS-17382 In situ consideration of resistance of bridge girder according to EC2 with AEM The paper presents a case study of a considerably cracked and degraded bridge in Slovenia: with the implementation of in-situ measurements under bending and shear and the use of a non-destructive acoustic emission technique. Despite the existing crack system, the latter was able to detect microstructural changes. These were characterised by low values of average frequency (AF), as well as lower values of the rise time-amplitude ratio (RA), and energy. A correlation between shear capacity and acoustic activity was observed. This promises to expand the use of AE in the process of assessing of the load-bearing capacity of existing concrete structures. shear resistance shear crack crack width acoustic emission (AE) parameters bridge girder stiffness elasticity damage evaluation strižna odpornost strižna razpoka širina razpoke parametri akustične emisije (AE) nosilec mosta togost elastičnost ocena poškodovanosti true false true N D T Internet Publishing Angleški jezik Slovenski jezik © 2023 The Authors Neznano 2023-11-28 15:19:49 2023-11-28 15:19:50 2023-11-29 03:38:02 0000-00-00 00:00:00 2023 0 0 Nasl. z nasl. zaslona; Opis vira z dne 6. 2. 2023; str. 1-10 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2023-01-01 620.1/.2 1435-4934 10.58286/27603 140787203 https://www.ndt.net/search/docs.php3?MainSource=299 1 ceec5aea-8df0-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23607 RAZ_Bruncic_Ana_2023.pdf RAZ_Bruncic_Ana_2023.pdf 1 17F913D59BEBBA05CA933C6F6378A199 712bb8762b36f6949825871a798240d69ec0d0c50718d6f61ed8880a84638725 91fabcd3-8df1-11ee-9ccb-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=23608 Zavod za gradbeništvo Slovenije 0 0 0
