Potresna analiza jeklene konstrukcije visokoregalnega skladišča (VRS2) = Seismic analysis of a steel frame high-rack warehouse structure (VRS2)Kilar, Vojko ; Koren, David, 1982- ; Petrovčič, SimonV prispevku je prikazana analiza obnašanja obstoječe jeklene konstrukcije visokoregalnega skladišča (VRS2) podjetja Trimo d.d. v Trebnjem pri potresni obtežbi. Konstrukcija je bila projektirana po ... standardih Evrokod 3 in 8. Posebna pozornost je posvečena 3D modeliranju in analizi konstrukcije. Zaradi obsežnosti modela je bila potresna analiza izvedena z nelinearno statično analizo (N2 metodo). Poleg osnovne simetrične variante smo analizirali tudi primere pri katerih je skladiščna masa razporejena nesimetrično po tlorisu. Ob tem so bile upoštevane tudi različne stopnje zasedenosti skladišča. Rezultati kažejo, da je obnašanje simetrične konstrukcije pri projektni potresni obremenitvi (ag = 0,175g) dobro. Preverili smo tudi primere nesimetrične obremenitve skladišča, do katerih lahko pride ob različnih kombinacijah zasedenosti, in ekscentričnost. Ugotovljeno je bilo, da lahko pri nekaterih ekscentričnostih nastopijo tudi plastični členki ob vpetju stebrov v regalih na podajni strani konstrukcije. Pri močnejši potresni obremenitvi (ag = 0,25g)bi pri takem obtežnem primeru lahko prišlo do neduktilnih poškodb in posledično do lokalnih nestabilnosti nekaterih regalov. Zato je bila analizirana in predlagana resitev z uporabo potresne izolacije z elastomernimi ležišči, ki se je izkazala kot učinkovita in primerna.Source: Zbornik 31. zborovanja gradbenih konstruktorjev, Rogaška Slatina, 8.-9. oktober 2009 (Str. 281-290)Type of material - conference contributionPublish date - 2009Language - slovenianCOBISS.SI-ID - 2328964
