Popis:	Prikazana je opsežna, ali ipak relativno jednostavna nelinearna metoda za ocjenu seizmičkog ponašanja konstrukcija (metoda N2). U metodi se nelinearni proračun kombinira s pristupom osnovanim na spektralnom odzivu, a dobivaju se relativno točni rezultati ako konstrukcija oscilira u prvom tonu. Opisuje se verzija metode formulirana u obliku ubrzanje-pomak. Metoda je ilustrirana primjerom četverokatne armiranobetonske okvirne zgrade. Metodom su nedavno obuhvaćeni i mostovi. Extensive but still relatively simple nonlinear method for evaluating seismic behavior of structures (N2 method) is presented. In this method, the nonlinear analysis is combined with the approach based on spectral response. Results can be relatively accurate if the structure oscillates in the first mode. An alternative of this method, formulated in acceleration - displacement format, is described. The method is illustrated through an example involving a four-story reinforced concrete frame building. As of recently, the method can also be used for bridges.
