Abstract
V diplomski nalogi je predstavljena statična analiza dvoetažne jeklene pravokotne poslovne stavbe. Konstrukcijo objekta sestavljajo momentni okvirji v obe smeri, ki so sestavljeni iz dvojnih HEB stebrov in IPE nosilcev. Notranje sile so določene z globalno elastično analizo z upoštevanjem teorije II. reda in globalnih začetnih nepopolnosti. Nosilnosti elementov, prerezov in spojev so dimenzionirani na mejno stanje nosilnosti, mejno stanje uporabnosti, potresno in požarno nezgodno stanje. Za določanje notranjih statičnih količin je uporabljen program SCIA Engineer. Največji poudarek diplomske naloge je na določanju požarne odpornosti jeklene stavbe po poenostavljeni metodi iz standarda SIST EN 1993-1-2. Nosilnost elementov je analizirana pri zahtevani odpornosti R30. S pomočjo nomogramov so določene temperature v jeklenem prerezu in nato odčitani redukcijski faktorji nosilnosti. Na koncu diplomske naloge so prikazani še načini požarne zaščite, ter postopki določitve požarne odpornosti pri požarno zaščitenih jeklenih elementih po poenostavljeni metodi.

Title:Fire design of steel office building
Abstract:
In this graduation thesis the static analysis of a duplex rectangle business building made of steel moment resisting frames in both directions is done. The columns are made of double HEB profiles and beams of IPE profiles. The global analysis was performed taking into account II. order analysis and initial geometric imperfections. For this purpose SCIA Engineer was used. The design of elements, cross-sections and joints was done for the ultimate limit state, serviceability limit state and for the earthquake and fire design situation. The main focus in this work was to determine fire resistance of the steel building through simplified method of standard SIST EN 1993-1-2. Capacity of elements was analysed for requested resistance R30. Using nomographic charts the temperatures in steel section and the reduction factor for capacity were determined. Finally, to resist the forces for the fire design situation, the fire protection of the steel elements was determined.
