Fire design of steel frame building |
Secondary abstract: |
This graduation thesis deals with static analysis and design of three story office building with the focus on fire resistance using simple design methods. Main structure consists of moment resisting frames in transverse direction and frames with bracings and composite beams in longitudinal direction. Second order analysis including global initial imperfections was used to determine internal forces. For this purpose SCIA Engineer software was used. Seismic analysis was made using method with horizontal forces. In longitudinal direction the horizontal forces were transferred using concentric braced system. Construction is deigned in accordance with special rules for medium ductility level. Fire-resistance class for structure is R30. To provide building’s fire resistance beams and columns are protected using gypsum slabs. Composite beams are partially embedded in concrete. |

Abstract (ePrints): |
V diplomski nalogi je obravnavana statična analiza in dimenzioniranje tri-etažne poslovne stavbe s poudarkom na preverjanju požarne odpornosti konstrukcije z uporabo enostavnih metod. Nosilno konstrukcijo v prečni smeri predstavljajo momentni okvirji v vzdolžni smeri pa okvirji s centrčnim povezjem in s sovprežni nosilci. Analiza konstrukcije je bila opravljena po elastični analizi II. reda z upoštevanjem začetnih geometrijskih nepopolnosti. Za izračun notranjih statičnih količin smo uporabili program SCIA Engineer. Potresna analiza je bila opravljena po metodi horizontalnih sil. Za prevzem horizontalne obtežbe v vzdolžni smeri uporabimo diagonalno centrično povezje. Ker je objekt načrtovan za potresno območje, morajo vsi spoji biti polnonosilni. Konstrukcija je načrtovana po pravilih nosilnosti za konstrukcije srednje stopnje duktilnosti (DCM). Zahtevana požarna odpornost stavbe je R30. Za zagotavljanje predvidene požarne odpornosti je potrebno prečke in stebre zaščititi z mavčnimi ploščami, prečke v sovprežnem nosilcu pa delno obetoniramo. |
