 Summary:
 Methods used for the design of structures in seismically active areas are based on structural behaviour assessment. Basic elements of such analysis are seismic hazard and seismic demand assessment of the structure. For the design of reinforced concrete structures, linear elastic models combined with response spectra (EN 1998-2) are applied. These methods provide a good estimate of seismic forces, but are insufficient in determining the displacements and deformations, which are crucial for the post-elastic behaviour that depends on the provided balance between stiffness, bearing capacity and ductility. In this paper, nonlinear dynamic analysis for the assessment of seismic behaviour of reinforced concrete girder bridge designed in accordance with EN 1998-2 is presented. Seismic excitation is introduced by applying accelerograms corresponding to the designed seismic action.
