Račun požarne odpornosti aluminijastih konstrukcij : diplomska naloga

Kovačič, Andraž (author), Hozjan, Tomaž (mentor)

V diplomski nalogi je predstavljena primerjava požarne odpornosti jeklenega in aluminijastega linijskega nosilca. Predvideni nosilec je del fasadne konstrukcije, ki prenaša obremenitev lastne teže konstrukcije in vpliva vetra. V prvem delu naloge so predstavljena splošna pravila varnosti konstrukcij pred požari in zakonodaja, ki narekuje varnostne zahteve. Nato so predstavljene splošne mehanske in toplotne lastnosti jekla ter aluminija pri povišani temperaturi. V osrednjem delu so opisane glavne kontrole nosilnosti, ki so povzete po standardu Evrokod 3 in Evrokod 9. Pri tem so izpostavljene glavne razlike dimenzioniranja med obema materialoma. Sledita računska primera požarne odpornosti jeklenega in aluminijastega nosilca izpostavljenega standardni požarni krivulji ISO 834. V zaključku naloge so predstavljene ugotovitve rezultatov, ki so bili dobljeni v računskem delu naloge.

• Title: Fire resistance of aluminium structures : Graduation thesis

Abstract

This thesis studies and compares the fire resistance of steel and aluminium planar beams. Analyzed beam is part of a facade construction that transmits the load of its own weight and the influence of the wind. The introduction describes the general rules for structural fire safety and safety regulation. Furthermore, the general mechanical and thermal properties of steel and aluminium at an elevated temperature are presented. The main focus of the thesis is on the design rules which are summarized after the Eurocode 3 and Eurocode 9 standards. The main differences in designing between the two materials are also highlighted. Moreover, fire resistance calculations of the steel and aluminium beam according exposed to the standard fire curve ISO 834 are shown. The conclusion presents the results obtained in the computational part of the thesis.
