Abstract

Glavna tema ovog diplomskog rada je analiza izgrađene čelične hale za proizvodnju peleta na različite požarne situacije i proračun konstrukcije na požar prema HRN EN 1991-1-2 i HRN EN 1993-1-2. Proveden je i proračun elemenata u 'hladnom stanju' gdje su razmatrana djelovanja vlastite težine, vjetra, snijega i potresa. Uz navedeno, izrađeno je dispozicijsko rješenje konstrukcije, te su riješeni glavni priključci okvirnog sustava. Konstrukcija čelične hale za proizvodnju peleta, u mjestu Žakanje, tlocrtno je pravokutna; dužine 78,0 m, širine 19,4 m i visine 6,4 m u strehi. Krov je dvostrešan pod nagibom 10°. Požar je razmatran kao izvanredno djelovanje, a zahtijevana požarna otpornost konstrukcije je R30. Za dobivanje odnosa temperatura - vrijeme korišten je programski paket Ozone v2.2. Razmatranjem nekoliko različitih požarnih scenarija napravljena je kompletna analiza u programskom paketu SCIA Engineer 19.0. Nakon toga provedena je ručna provjera požarne otpornosti. Uz suvremene metode simulacije razvoja realnog požara i proračuna čeličnih konstrukcijskih elemenata na povišene temperature, dokazano je da razmatrana čelična konstrukcija bez protupožarne zaštite zadovoljava zahtjev za požarnu otpornost od R30.

Abstract (english)

The main topic of this diploma thesis is the analysis of already built pellet production steel hall for different fire situations and the structural fire design according to HRN EN 1991-1-2 and HRN EN 1993-1-2. The calculation of the elements in the 'cold state' was also performed, where the effects of self-weight, wind, snow and earthquake were considered. Furthermore, structural steel layout drawing was made and main structural frame joints were resolved. The structure of the steel pellet production hall, located in Žakanje, is rectangular in plan: 78,0 m long, 19,4 m wide and 6.4 m high in the eaves. The roof is double-sided with a slope of 10°. The fire was considered as an accidental action and required fire resistance is R30. Ozone v2.2 software was used to get the temperature-time relationship. Considering several different fire scenarios, a complete analysis was made in SCIA Engineer 19.0 software package. After that, a manual fire resistance check was performed. With modern methods of simulating the development of real fire and design of steel structural members at elevated temperatures, it has been proven that a considered steel structure without fire protection satisfies the requirement for fire resistance of R30.
