This paper discusses the steps that are necessary in assessing the seismic performance of existing and new transportation structures, including (1) characterizing expected ground motions, (2) setting performance criteria, (3) modelling and dynamic analysis, and (4) interpreting predicted dynamic response behavior. To establish a basis for assessing the performance of older existing bridges, the history of loading criteria over the past 50 years, as specified in the U.S. AASHO/AASHTO national bridge code, is reviewed.
