Abstract

U sklopu rada prikazana je procjena stanja konstrukcije stambene zgrade u Zagrebu koja je oštećena u potresu 22.3.2020. godina. Magnituda potresa iznosila je 5.5 stupnjeva po Richteru. Obavljen je detaljni pregled zgrade u svrhu procjene stanja konstrukcijskih elemenata kako bi se provela analiza mehaniče otpornosti i stabilnosti zgrade na temelju koje su preporučeni daljnji postupci. Nosivi sustav zgrade čini neomeđeno ziđe međusobno povezano fleksibilnom međukatnom konstrukcijom, a krovište... More drvenom konstrukcijom. Razina oštećenja konstrukcijskih i nekonstrukcijskih elemenata zgrade su klasificirana te su njihovi opisi nadopunjeni odgovarajućim fotografijama zabilježenim na lokaciji. U svrhu procjene potresne otpornosti napravljen je proračun otkazivanja nekoliko karakterističnih zidova izvan ravnine. Nadalje, izrađen je numerički model u programu CSI ETABS 17.0.1 gdje je proveden linearni proračun metodom spektra odziva. Zaključno su predložena tehnička rješenja popravka i pojačanja nosive konstrukcije. Less

Abstract (english)

Within this graduate thesis, analysis of the construction of a residential building in Zagreb that was damaged in earthquake of March 22, 2020 is shown. The magnitude of the earthquake was 5.5 according to the Richter scale. A building survey was performed in order to assess the structural elements condition in order to analyse mechanical resistance and stability of the building. Based on the performed analysis, certain suggestions were given to take further actions. The load bearing system of... More the building consists of unreinforced masonry with a flexible floor structures and the roof structure made of wood. Damage states of various structural, as well as non-structural elements are classified and appropriate photographs of damage caused by the earthquake complement their descriptions. In order to asses building seismic resistance, a computation of the out-of-plane failure for several characteristic walls is made. Furthermore, a numerical model was developed in CSI ETABS 17.0.1 where a linear computation was performed by the response spectrum method. To conclude it all technical solutions for repair and reinforcement of the load bearing structure are being suggested. Less
