| Abstract: | This paper discusses the principal factor,the structural damping ratio affecting response spectrum in code of seismic design of highway bridges.Through comparative analysis of domestic and foreign response spectrum modification formulas,the paper also proposes a modification method for the response spectrum in the code when the damping ratio of the spectrum is not 5%.The proposed method herewith provides reference basis for revising the code and for seismic design of highway bridges. |
