000013746 520__ $$2eng$$aThe seismic safety assessment of bridges using nonlinear static analysis methods is not straightforward. Not only an accurate modelling of the structural frames inelastic behaviour is required, but also a correct definition of the force distribution patterns, analysis directions, reference points and target displacements that best represents its seismic structural performance. This difficulty on the pushover parameters definition increases when irregular-in-plan bridges are considered, namely curved bridges. Hence, the aim of this study is to assess the seismic safety of a set of curved bridges using the eurocode’s pushover analysis method. Particular attention is paid to the RC columns biaxial behaviour modelling. The bridge structural response is evaluated in terms of global and local capacities. Comparative evaluation of the calculated response of the bridges illustrates the applicability of the N2 pushover method and the influence of the different directions of analysis in its local and global capacity demands definition.
