Abstract

V Sloveniji in v večjem delu Evrope so pri projektiranju gradbenih konstrukcij veljavni evropski standardi Evrokodi, ki ločujejo med stalnimi in začasnimi projektnimi stanji. Medtem ko se v analizi infrastrukturnih in industrijskih objektov, kot so mostovi, tuneli, montažne hale ipd. upoštevata obe projektni stanji, se v analizi stavb začasna projektna stanja pogosto zanemarjajo. Fazno aktiviranje lastne teže konstrukcije ter drugih stalnih in spremenljivih obtežb se lahko v določenih situacijah izkaže za ključno prav v času gradnje pa tudi po njej, ter vodi do drugačne prerazporeditve sil, kot je projektant predvidel z analizo zgolj končnega stanja konstrukcije. Magistrsko delo obravnava različne pristope k analizi konstrukcij in prek konkretnih primerov analizira rezultate ustaljene analize in analize z upoštevanjem faznosti gradnje. Izpostavljeni in analizirani so najpogostejši vzroki, ki vplivajo na razlike med pristopoma. V sklepu je podana ocena, pri katerih pogojih je analiza z upoštevanjem faznosti gradnje upravičena oziroma potrebna.

Secondary title:	Modeling of reinforced concrete high-rise structures considering construction stages
Secondary abstract:	In Slovenia and the larger part of Europe, valid European standards, i.e. Eurocodes, which separate between permanent and temporary design states, apply for the construction design. While the analysis of the infrastructure and industrial objects such as bridges, tunnels, prefabricated halls, etc. takes both design states into account, the analysis of buildings often neglects the temporary design state. Phased activation of the construction’s own weight and other constant and variable loads can be critical in certain situation during but also after construction. It can lead to a different weight distribution as the one foreseen by the designer who merely conducted a final state analysis of the construction. This master’s thesis shall deal with various approaches to the analysis of constructions and shall use different examples to analyse results of the standard analysis and the analysis based on the construction phases. The most common reasons that influence the differences between the approaches shall be emphasised and analysed. The conclusion shall give an assessment as to when the analysis based on the construction phase is justified or rather required.
