| Popis: | Magistrsko delo obravnava izračun požarne odpornosti jeklene okvirne konstrukcije in je vsebinsko razdeljeno na dva dela. V prvem delu določimo požarno odpornost konstrukcije po poenostavljenem postopku skladno s standardom SIST EN 1993-1-2 in z uporabo programa SCIA Engineer 16.0. V drugem delu pa je požarna odpornost konstrukcije preverjena z napredno metodo, pri čemer je uporabljen program POŽAR. Požarna odpornost je v obeh analizah izračunana za standarden ISO 834 in parametričen požar. Parametrične požarne krivulje so določene s programom Ozone V2.2 za dva požarna sektorja, in sicer za skladiščne prostore in pisarne. Obravnavamo šest različnih primerov, ki zajemajo izračune z ISO 834 požarno krivuljo in parametričnimi požarnimi krivuljami. Cilj dela je preveriti morebitne razlike med poenostavljeno in napredno računsko metodo ter prikazati vpliv vhodnih parametrov pri izračunu parametričnih požarnih krivulj na požarno odpornost obravnavane jeklene konstrukcije. The thesis discusses the calculation of fire resistance of a steel portal frame in terms of the content, it is divided in two sections. In the first section fire resistance of a structure is determined in line with the simplified calculation method in accordance with the SIST EN 1993-1-2 standard and by applying the software SCIA Engineer 16.0. In the second section, fire resistance of a structure is verified against the advanced method, by the use of software POŽAR. In both analyses, fire resistance has been calculated for a standard-temperature fire scenario ISO 834 and a "natural" (parametric) fire scenario. Parametric fire curves have been determined by applying software Ozone V2.2 for two fire sections, specifically, for warehouse premises and for offices. Several situations are examined which include analyses based on ISO 834 fire curve and parametric fire curves. The aim of the thesis is to present any potential differences between the simplified and the advanced calculation method and to present the impact of input parameters for the calculation of parametric fire curves in regard to fire resistance of the steel construction in question. |
