Abstract
V diplomskem delu je prikazan vpliv razvoja požara na požarno odpornost enostavnih lesenih nosilnih elementov skladno s standardoma SIST EN 1991-1-2 in SIST EN 1995-1-2. Požarna analiza lesenih nosilnih elementov je razdeljena v tri faze. V prvi fazi so s parametrično analizo vpliva parametrov na razvoj požara zasnovani požarni scenariji. Na osnovi pridobljenih rezultatov v drugi fazi sledi temperaturna analiza s katero je določena globina oglenenja lesenega stebra in lege za posamezni požarni scenarij. V zadnji fazi analize je določena požarna odpornost lesenega elementa za posamezni požarni scenarij. Parametrične študije pokažejo, da na požarno odpornost enostavnih lesenih elementov najbolj vplivajo izbrani aktivni ukrepi, največja hitrost sproščanja toplote požara na kvadratni meter, število in velikost odprtin v objektu ter toplotna absorptivnost konstrukcijskih sklopov. Medtem ko hitrost razvoja požara nima posebnega vpliva na požarno odpornost lesenih elementov.

Title:Parametric study of the fire resistance of simple timber elements
Abstract:
The graduation thesis presents the influence of fire development on fire resistance of simple timber bearing elements according to SIST EN 1991-1-2 and SIST EN 1995-1-2. The fire analysis of timber bearing elements is divided into three phases. Parametric analysis of influence of certain parameters on fire development is performed in the first phase. On the basis of acquired results second phase follows in which, thermal analysis of timber elements is conducted. Here, charring depths for timber elements for every fire scenario are determined. In the third, last part of analysis, fire resistance of timber elements is determined. Parametric studies show that fire resistance of simple timber elements is mostly affected by chosen active fire protection systems, the maximum rate of heat release per square meter, number and size of openings in the object and lastly thermal absorptivity of sctructural assemblies. However, fire growth rate does not have any special influence on fire resistance of timber elements.

Keywords:civil engineering, graduation thesis, fire resistance, timber elements, charring rate, zero strength layern
