Secondary title:	Fire protection of timber structures
Secondary abstract:	In civil engineering wooden structures are in use from the very beginning of the science. Timber is one of the most suitable materials for building fire safe constructions. The problem is that, even though timber has a good behavior when exposed to fire, is still a combustable material. That is also the crucial property of timber. On one hand a timber component provides fuel stock for a fire, on the other hand, because of the type of burning, the outside layer of a timber member becomes char, which provides protection for the core of the exposed element. This char layer prevents oxigen to come in contact with combustable gases that are a product of timber exposed to high temperatures. To extend the time of resistance of a timber structure, different kinds of protection are used. These materials differ in efficiency and layout. I analyzed four basic kinds of fire protective materials, comparing them in regard of the resistance results. For the analysis I made a tool in Microsoft Excel to help me calculating resistance for a timber column with the use of different fire protective materials.

Abstract (ePrints):	Lesene konstrukcije so že od nekdaj prisotne v gradbeništvu. Les velja za enega izmed bolj primernih materialov za gradnjo požarno varnih objektov. Težava je, da kljub ugodnemu obnašanju v primeru izpostavljenosti ognju, les spada med gorljive materiale. Ravno ta lastnost je bistvena pri lesenih elementih. Na eni strani lesena konstrukcija predstavlja dodatno kurilno zalogo v primeru požara, na drugi strani zaradi načina gorenja lesa, zunanja plast elementa zogleni in tako zagotovi požarno zaščito jedru. Zoglenela plast onemogoča dotok kisika, ki je potreben za gorenje plinov, ki se proizvajajo ob segrevanju lesa. Za podaljšanje časa odpornosti lesene konstrukcije se v praksi uporabljajo različna požarna izolacijska sredstva. Izolacijski materiali se zelo razlikujejo glede na učinkovitost in izgled. Pregledali bomo štiri osnovne vrste požarne zaščite in primerjali njihov učinek na požarno odpornost za leseni steber. Z uporabo programa Microsoft Excel sem izdelala programsko orodje za izračun požarne odpornosti lesenih stebrov z možnostjo upoštevanja različnih požarnih zaščitnih sredstev. Ugotovimo, da različna požarna zaščitna sredstva pomembno prispevajo k požarni odpornosti lesenega stebra, vendar ne v enaki meri. Na osnovi rezultatov lahko zaključimo, da so v obravnavanem primeru mavčno kartonske plošče tipa DF najbolj protipožarno učinkovite.
