Secondary title:	Analysis of reinforced concrete building according to the EC 8
Secondary abstract:	In the Thesis the analysis and the software based design of the six-storey reinforced concrete wall building according to the European Standard Eurocode is presented. The structural system of the building consists of reinforced concrete walls. First the calculation of the self weight, variable actions, snow and the wind loads has been examined. The major part of the thesis deals with seismic analysis, which was performed by the modal analysis and simplified non-linear seismic analysis. The structure was designed for the medium ductility class since the overstrength due to minimum requirements of reinforcements is high for the examined building. The presented analysis results are the periods and mode shapes, storey shears, the quantity of reinforcement in certain section and target displacement in the non-linear seismic analysis. Using the computer program ETABS, two structural models were constructed using only beam/column or shell elements. It is shown that result of analysis for both models are comparable. In addition it was shown that structural elements reinforced with minimum reinforcement defined in Eurocode 8 may resists to the design seismic action, if the structure has a great proportion of walls regarding to ground plan. We verified this claim also with computer program ETABS, which was used for automatic designed the elements of the structure.

Abstract (ePrints):	V diplomskem delu je predstavljena analiza in računalniško projektiranje šest etažne stenaste armiranobetonske konstrukcije po veljavnih evropskih standardih. Nosilno konstrukcijo objekta sestavljajo armiranobetonske stene. Prikazan je izračun lastne teže, koristne obtežbe, obtežbe snega in vetra. Pretežni del diplomske naloge je namenjen potresni analizi, ki smo jo izvedli z modalno analizo in poenostavljeno nelinearno analizo. Stenasta konstrukcija ima veliko dodatno nosilnost, zato smo jo projektirali na srednjo stopnjo duktilnosti. Rezultati analize so prikazani kot nihajni časi, etažne prečne sile in količina armature v izbranih stenah. Rezultat nelinearne analize pa so ciljni pomiki konstrukcije in poškodovanost po konstrukciji pri izbrani potresni obtežbi. Konstrukcijo smo modelirali z linijskimi in ploskovnimi elementi in sicer v programu ETABS. Rezultati so primerljivi. Dokazali smo, da šest etažna armirano betonska stenasta konstrukcija z velikim deležem sten proti tlorisni površini, potrebuje za prevzem potresne obremenitve le minimalno armaturo določeno po EC8. To trditev smo preverili tudi s programom ETABS, kjer smo konstrukcijske elemente tudi avtomatsko dimenzionirali.
