 Summary:
 In order to study the behaviour of the bridge under seismic actions, the Eqiuvalent Linearization Method (ELM) was applied. The bridge is continuous with three fields, ranging 24 + 40 + 24 m, with prestressed concrete box girder of constant height. The Nonlinear Static Pushover Analysis (NSPA) was applied. Bridge columns, exposed to horizontal seismic effect, were subject of detailed analysis, using the Type 1 Response Spectrum for category B type soil, according to EN1998: 2004. The analysis also includeda 20% of traffic load. Bridge columns were designed according to EN1992, parts 1 and 2.Result of the analysis are presented with pushover curves that describe the behaviour ofelements under seismic actions in longitudinal and transverse directions.
