Pushover analysis of RC bridge designed according to EN 1998-2

Engineering and construction of roads, subways, airfields, bridges and transport tunnels

Contemporary structural design implies nonlinear behavior of ductile members for design seismic action and thus, the application of nonlinear analysis is required. Nonlinear static pushover analysis enables determination of nonlinear deformations and ductility demands in previously defined critical regions. This paper presents the analysis of reinforced concrete Girder Bridge designed according to EN 1998-2, with the determination of the achieved ductility in plastic hinges at the target displacement for the designed seismic action, for confined and unconfined concrete cross sections, with and without the effects of geometric nonlinearity.
