Method for estimating seismic behavior of builings and bridges

Petar Fajfar, Matej Fischinger, Tatjana Isaković

Abstract

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.
