Non-linear time-history analysis is the most reliable method to evaluate the responses of bridges subjected to seismic loads. Canadian Highway Bridge Design Code, American Association State Highway and Transportation Officials require using spectrum-compatible accelerograms for time-history analysis. This paper presents four methods for obtaining spectrum-compatible accelerograms for time-history analysis of bridges in eastern Canada where real earthquake records are lacking. Based on the procedure given by these methods, four sets of accelerograms were selected for the study, namely; scaled real accelerograms, modified real accelerograms, simulated accelerograms and artificial accelerograms. In order to determine the suitable type of accelerograms for the seismic analysis, two reinforced concrete bridges located in Montreal, Canada were examined. Based on the results obtained simulated accelerograms are recommended to conduct time-history analysis of bridges in eastern Canada
