magistrsko delo
Povzetek
Preučevali smo uporabnost razširjene N2 metode na primeru tipične osem etažne armiranobetonske
stenaste stavbe. V nalogi smo prikazali analizo in dimenzioniranje glavnih nosilnih elementov
konstrukcije kot tudi pripravo modela za nelinearno analizo. Pri dinamičnih analizah smo uporabili 10
različnih akcelerogramov s po dvema vodoravnima komponentama. Opravili smo parametrično študijo
obnašanja konstrukcije pri različnih kombinacijah smeri delovanja potresne obtežbe in dveh jakosti
potresne obtežbe. Primerjali smo rezultate parametrične študije z rezultati iz razširjene N2 metode. Iz
rezultatov in primerjav smo lahko zaključili, da razširjena N2 analiza daje inženirsko zadovoljive in
smiselne rezultate. Hkrati smo na primeru pokazali, da je razširjena N2 metoda dovolj enostavna in
primerna za uporabo v inženirski praksi. Poleg tega se je pokazalo, da je vpliv izbire smeri delovanja
potresne obtežbe pomemben, saj lahko pride pri različnih kombinacijah smeri in predznaka dveh
komponent istega akcelerograma do precejšnjih razlik v odzivu konstrukcije. V nalogi smo izpostavili
tudi nekatere probleme pri samem dimenzioniranju elementov in pri pripravi nelinearnega modela.
Težave pri zajemanju in ovrednotenju velike količine rezultatov, ki jih dobimo pri nelinearnih
dinamičnih analizah, nakazujejo prednost razširjene N2 metode.

Estimation of the applicability of the N2 method for a typical RC wall building |
Sekundarni povzetek: |
The application of the extended N2 method for a typical eight storey reinforced concrete wall building
has been studied, which is due to its layout at the limit of the applicability of N2 method. In the master
thesis analysis and design of the main load-bearing elements as well as the modelling for the nonlinear
analysis and non-linear analysis itself have been performed. For dynamic analyses 10 different
accelerograms with two horizontal components were used. Parametric studies of the structure’s
behavior for several different combinations of earthquake loading directions and for two earthquake
loading intensities were performed. The comparison of the parametric study results with the extended
N2 method results confirmed that the extended N2 method provides adequate and reasonable results to
the user. Also it has been shown that the extended N2 method is simple enough for use in every-day
engineering work. In addition, it was demonstrated that the choice of the earthquake loading direction
is important. Different combinations of the direction and sign of two components of the same
accelerogram can yield quite different structural response. In the master thesis some problems related
to dimensioning of structural elements and to the preparation of a non-linear model are pointed out.
Difficulties related to fetching and evaluating the large amount of data obtained when performing a
non-linear time history analysis suggest the advantages of the N2 method. |
