Abstract
V članku najprej predstavljamo najpomembnejše izsledke eksperimentalnih raziskav s področja kompozitnih konstrukcij iz lesa in betona v požaru in pregled poenostavljenih metod za določanje njihove požarne odpornosti. V drugem delu prispevka pa s prikazom dejanskega izračuna izvedemo primerjavo postopka določitve požarne odpornosti kompozitnega nosilca iz lesa in betona po dveh izmed obstoječih poenostavljenih metod. Pri tem se osredotočimo na pomembnejše razlike v postopku, na oceno zahtevnosti postopka in seveda na primerjavo dobljenih rezultatov. Namen celotnega prispevka je bralcu približati odziv vedno bolj priljubljenih kompozitnih konstrukcij iz lesa in betona v požarnem projektnem stanju, ki sicer v trenutno veljavnih Evrokodih še niso zajete, pripravlja pa se njihova vključitev v prihodnje izdaje standardov.

Title:Timber-concrete composite structures in fire : a literature review with comparison of simplified methods
Abstract:
The article begins with the presentation of the most important findings of experimental investigations on timber-concrete composite structures in fire, together with an overview of simplified methods for the determination of fire resistance of timber-concrete composite elements. In the second part of the article, a worked example of calculation of the fire resistance of a timber-concrete composite beam is given. Here, two of the existing simplified methods are used and thus compared. The focus is on the most notable differences between both procedures, on the assessment of their complexity and on the comparison of the obtained results. The aim of the entire article is to provide the reader with information on the response of increasingly popular timber-concrete composite structures in fire, which are somewhat overlooked in the currently active Eurocodes, although their inclusion in future editions of European standards is already in preparation.

Keywords:composite structures, timber, concrete, fire, literature review, comparison of simplified methods, worked example
