Abstract

Provedena je analiza pet numeričkih modela kako bi se ispitali utjecaji različitih faktora na ponašanje konstrukcije i razinu oštećenja uzrokovanu potresom. Svi modeli su višeetažni, prostorni, armiranobetonski okviri. U skladu s Eurokod 8 smjernicama, proračunati su bilinearni dijagrami moment-zakrivljenost na temelju kojih se u software-u ETABS definiralo ponašanje plastičnih zglobova stupova i greda. Zatim se provela metoda postupnog guranja kako bi se dobio uvid u raspored otkazivanja elemenata pojedinih modela. Rezultati nelinearne analize metodom postupnog guranja predstavljeni su u obliku krivulje kapaciteta koja prikazuje ovisnost poprečne sile u razini temelja i pomaka vrha građevine za različite oblike opterećivanja. Ponašanje tih konstrukcija uspoređeno je preko potresnih zahtjeva pojedinih sustava.

Abstract (english)

An analysis of five numerical models was carried out in order to examine an influence of various factors on the behaviour of the structure and the level of damage caused by an earthquake. All models are multi-storey, spatial, reinforced concrete frames. In accordance to the Eurocode 8 guidelines, bilinear moment-curvature diagrams were calculated, based on which the behaviour of plastic hinges of columns and beams was defined in the software ETABS. In addition, pushover method was carried out in order to gain an insight of a failure mechanism pattern. The results of the nonlinear analysis are presented in the form of a capacity curve which represents base shear and roof displacement relationship for different load patterns. The behaviour of these structures was compared through seismic demands of individual systems.
