Abstract

V diplomski nalogi obravnavamo zasnovo in dimenzioniranje štiri-etažne industrijske stavbe v obsegu projekta za pridobitev gradbenega dovoljenja. Nosilno konstrukcijo predstavlja 6 upogibnih okvirjev z razponom 9 metrov na medosni razdalji 10 metrov, ki potekajo v prečni smeri objekta. Horizontalna nosilnost v vzdolžni smeri je zagotovljena s centričnimi povezji. Stropna konstrukcija je zasnovana kot sovprežna plošča, ki se podpira na sekundarne sovprežne nosilce, ki so členkasto priključeni na primarne jeklene nosilce konstrukcije. Vplive na konstrukcijo smo določili iz slovenskih standardov SIST EN 1991 in SIST EN 1998. Globalno analizo smo naredili z dvema ravninskima modeloma v računalniškem programu SCIA Engineer 2013.1, izračunana pa je z elastično analizo po teoriji drugega reda z upoštevanjem začetnih globalnih geometrijskih nepopolnosti. Posebna pozornost je posvečena potresni analizi in dimenzioniranju na potresno projektno stanje. Disipacijo energije predvidimo v prečkah ter v centričnih povezjih, medtem ko stebre varujemo. Ob stikih prečk s stebri pride do velikih negativnih momentov, zato na teh mestih nosilec ojačamo z vutami, na pasnicah prečk pa predvidimo oslabitev. Tako dosežemo optimalno izkoriščenost le teh, kar v nadaljevanju vpliva na optimalno izbiro dimenzij stebrov. V mejnem stanju nosilnosti (MSU) preverimo pomike, ki se izkažejo za skladne s standardom.

Secondary title: Seismic design of four-storey industrial building
Secondary abstract: This graduation thesis examines the concept and design of a four-storey industrial building within the scope of the project to obtain a building permit. The supporting structure is constituted by 6 steel moment resisting frames with a 9-metre span, running transversely every 10 meters along the length of the building. Longitudinal horizontal load capacity is provided through concentric bracing. Floors are designed as a composite slab supported by secondary composite beams, which are simply supported by the primary steel beams. Influences on the structure are predicted in accordance with Slovenia's SIST EN 1991-1998 standard. Global analysis was made using two planar models in a SCIA Engineer 2013.1 program environment, while calculations were undertaken through an elastic analysis with consideration of the initial geometric imperfections and second order theory. Special attention was dedicated to seismic design. Dissipation of energy is provided in the beams and concentric bracing in order to protect the columns. Due to the numerous negative moments calculated, the junctures of beams with columns were reinforced with haunches. In achieving optimum utilization, the choice of column dimension is affected by the projected weakening at the flanges of beams. In the assessment of the serviceability limit state, displacements appear to be consistent with the given recommendations.
