摘要
对影响公路桥梁抗震设计规范反应谱的主要因素—结构阻尼比进行讨论,通过对国内外的反应谱修正公式进行对比分析,提出公路桥梁抗震设计规范反应谱的阻尼比不是5%时的反应谱修正方法,为公路桥梁抗震规范的修订和公路桥梁的抗震设计提供参考依据。
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 5G. The proposed method herewith provides reference basis for revising the code and for seismic design of highway bridges.
