20.500.12556/DiRROS-18570 Modelling of traffic load effects in the assessment of existing road bridges Modeliranje utjecaja prometnoga opterećenja u postupku ocjenjivanja postojećih cestovnih mostova Traffic load models used for the design of new bridges are based on conservative assumptions and have not been proven efficient for assessing safety of existing bridges. In the case of existing bridges, it is reasonable to use load models that are based on bridge weigh-in-motion data which, in addition to axle loads and spacing of bridge-crossing vehicles, provide information on bridge behaviour under traffic load. This paper provides an overview of traffic load models, as well as guidelines on the use of weigh-in-motion data when assessing condition of existing road bridges. Modeli prometnoga opterećenja koji se primjenjuju pri proračunu novih mostova temelje se na konzervativnim pretpostavkama te se njihova upotreba u analizi postojećih mostova nije pokazala učinkovitom. Kod postojećih mostova preporučena je primjena modela prometnoga opterećenja temeljenog na mjerenju prometa u pokretu, koji osim osovinskoga opterećenja i razmaka, daje i podatke o ponašanju mosta pod prometnim opterećenjem. U ovome su radu dani pregled modela prometnoga opterećenja te smjernice o upotrebi podataka dobivenih mjerenjem prometa u pokretu prilikom ocjene stanja postojećih cestovnih mostova. prometna obtežba tehtanje vozil med vožnjo mostni WIM ocenjevanje stanja obstoječi mostovi traffic load weigh-in-motion bridge WIM condition assessment existing bridges true false true Hrvatski savez građevinskih inženjera Angleški jezik Hrvaški jezik © authors, 2019 Neznano 2024-03-27 08:05:57 2024-03-27 08:18:59 2024-03-28 03:33:43 0000-00-00 00:00:00 2019 0 0 str. 1153-1165 br. 12 Vol. 71 2019 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2019-12-10 624 0350-2465 10.14256/JCE.2609.2019 2515303 RAZ_Skokandic_Dominik_2019.pdf RAZ_Skokandic_Dominik_2019.pdf 1 F8F5C2DA2FB1E8B4A5608EF61DDEB249 50c2d3c6f6e5f39166d43b556af3ca01a906071cce73b2e4415807a6a84ae4af c3b8e28e-ec01-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25317 RAZ_Skokandic_Dominik_2019.pdf RAZ_Skokandic_Dominik_2019.pdf 1 86181CD943893D22CED8ACF75CA76E2B cf94a77e85f6689b092ebd65b6d6790a24645a9df7e562cec8ab54b24299be1c ce8dafbf-ec01-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25318 http://dx.doi.org/10.14256/JCE.2609.2019 0 a2ab7b19-ec01-11ee-9dd4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=25316 Zavod za gradbeništvo Slovenije 0 0 0
