	Summary:
	In this paper two different methods of selection and scaling ground motion data were investigated in order to examine their effect on accuracy predicting seismic response of RC bridge. First method used is one proposed in EN 1998-2 and second method is scaling of earthquakes based on calculated conditional mean spectrum (CSM) related known parameters of earthquake scenario for certain location. For both methods certain limitations upon scaling factor were implemented in order to examine its effect on accuracy. Totally 4 sets consisted of 7 records were selected, and average seismic response were obtained from nonlinear dynamic analysis. Responses were compared to calculated real response of bridge, so called point of comparison. Conclusions were made about investigated methods accuracy and effect on imposed limitation of scaling factor on realistic prediction of seismic bridge response.
