A relatively simple probabilistic approach for the seismic performance assessment of building structures combines the SAC-FEMA method, with the N2 method. In this approach, the most demanding part of the PEER probabilistic framework, i.e. the Incremental Dynamic Analysis (IDA), is replaced by the much simpler Incremental N2 (IN2) analysis. The results of the analyses indicate that the probability of failure of the infilled frames with regularly distributed infill is smaller than that of the bare frame.

Poenostavljene nelinearne metode v potresnem inženirstvu so osnovane na nelinearni statični analizi in na nelinearnih spektrih odziva. Ena izmed takšnih poenostavljenih metod je N2 metoda, ki je bila razvita na Univerzi v Ljubljani, in implementirana v standard Eurocode 8. V tej študiji smo nelinearne spektre, ki so uporabljeni v N2 metodi, nadomestili z SDOF-IDA krivuljami, ki so izračunane na osnovi štiri-linearne idealizacije pushover krivulje. Predlagana metodologija je uporabljena na primeru štiri-etažne armiranobetonske konstrukcije.
