The dynamic behavior of highway bridges under moving vehicles is analyzed, and then the effects of roadway roughness to dynamic response of the bridges are investigated quantitatively. In this study the dynamic behavior of bridges under moving vehicles is termed the “dynamic factor”, and the spectral characteristics of roadway roughness on bridges is classified into the four categories according to the method of evaluation of roadway condition indicating by authors's investigation. Numerical calculations are presented to investigate the effects of roadway characteristics to the dynamic response.
