20.500.12556/DiRROS-25534 Laboratory testing of old bridge girders preliminary results This paper presents key results on the laboratory testing of old girders removed from a flood-damaged bridge located near Ljubljana, Slovenia. The structure was widened in 1989 to accommodate pedestrians and cyclists by integrating prefabricated prestressed reinforced concrete T-girders. To assess the structural behaviour of the bridge, six girders were subjected to a rigorous testing program involving bending and shear tests in a laboratory setting. The tests were performed on girders with static lengths of 12.20 meters and 9.90 meters. The program aimed to evaluate the structural performance of the girders. Preliminary results indicate satisfactory structural behaviour of the prestressed T-girders under the applied loads, with insights into their performance under both bending and shear stresses. This study contributes valuable data for assessing the long-term behaviour of bridges. The outcomes are particularly relevant for optimising resource allocation in bridge rehabilitation projects and ensuring safety and functionality in transportation networks. laboratory testing prestressed girders assessment load test operational modal analysis damage acoustic emission laboratorijsko testiranje prednapeti nosilci ocena stanja obremenilna preizkušnja obratovalna modalna analiza poškodba akustična emisija true false true Verlag der Technischen Universität Graz Angleški jezik Slovenski jezik Neznano 2026-01-22 11:18:15 2026-01-22 11:21:57 2026-01-24 03:41:01 0000-00-00 00:00:00 2025 0 0 Str. 1073-1076 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-09-06 624 10.3217/978-3-99161-057-1 259884035 256692995 http://dx.doi.org/10.3217/978-3-99161-057-1-161 0 af1ac6f4-f77b-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38709 RAZ_Kreslin_Maja_2025.pdf RAZ_Kreslin_Maja_2025.pdf 1 BD94B6280B3605E0A28DFCD710A3C9E9 64ffded3d5a9133cf1cbc5b14e76760bd5151a28bc2342ddb356d7467291c6c6 0afd18ef-f77c-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38710 Zavod za gradbeništvo Slovenije 0 0 0
