The simplified approach is based on the method isotherm 500°C, which is given in SIST EN 1992-1-2:2005. The main part of the paper is focused on the advanced calculation method that consists of two parts. Firstly, the advanced hygro-thermal model is used to determine the temperature field in the characteristic cross-section of the concrete hollow-core slab during fire. Secondly, stress-strain state of prestressed hollow-core slab is determined based on the geometrically and materially non-linear beam model, where also slip between concrete and tendon is considered. Parametric study demonstrated that slip modelling between concrete and tendon is essential to accurately estimate the behaviour and fire resistance of prestressed hollow-core slab"},{"@xml:lang":"sl","#text":"Članek prikazuje uporabo poenostavljenega in naprednega načina določitve požarne odpornosti prednapete votle plošče. Poenostavljen način temelji na uporabi metode izoterme 500 °C, ki jo podaja SIST EN 1992-1-2:2005 in spada med uveljavljene postopke za določitev požarne odpornosti nosilcev, izpostavljenih standardnemu požaru. Drugi, napredni način, ki predstavlja osrednji del prispevka, pa je razdeljen na dva dela. Najprej uporabimo napredni toplotno-vlažnostni model za določitev temperaturnega polja v karakterističnem prečnem prerezu plošče. Nato določimo napetostno-deformacijsko stanje plošče med požarom na osnovi geometrijsko in materialno nelinearnega modela nosilca z upoštevanje zamika med betonom in kabli. Na podlagi parametrične študije je bilo ugotovljeno, da upoštevanje zdrsa med betonom in kabli bistveno vpliva na odziv in požarno odpornost prednapete votle plošče"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-IRRRNZXB","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-IRRRNZXB"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-IRRRNZXB/8140fcb7-69ca-4eeb-aaa3-015476a090d1/PDF"},"edm:rights":{"@rdf:resource":"http://creativecommons.org/licenses/by-nc-sa/4.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Zveza društev gradbenih inženirjev in tehnikov Slovenije"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-IRRRNZXB/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-IRRRNZXB"}}}}
