	Summary:
	The probability of a severe earthquake in the course of structures lifetime is small, and that results in economic ineffectiveness of designing structures that will not be damaged in the event of a project earthquake. In the case of RC bridges, the common practice is the controlled appearance of damage in the piers, while the girder is designed in such a way that it remains in the linearly-elastic domain. In EN 1998-1 and EN 1998-2, methods for determining seismic actions based on linear elastic models are prescribed, the basic method for determining seismic actions is modal analysis with response spectra, which leads to a sufficiently good assessment of seismic forces. However, a qualitative estimate of the deformation quantities, which are of key importance in the event of damage, can only be carried out using nonlinear analysis methods. This paper summarizes the basic recommendations for the modelling of RC girder bridges for assessing seismic performance using nonlinear static and nonlinear dynamic analysis.
