| 摘 要： | 不同阻尼比的反应谱的转换关系在我国各类抗震设计规范中有重要应用。以大崎顺彦的转换关系为数学模型,以包含可靠长周期信息的260条基岩记录为基础,进行统计分析,得到新的0.04—10 s的不同阻尼比反应谱的转换关系。新转换关系弥补了4—10 s的长周期部分,并首次考虑了距离对强震持时的影响,可以应用于阻尼比连续变化的反应谱的转换。先对0.04—4 s内的数据回归出结果,与大崎顺彦的结果作对比。然后,再对0.04—10 s内的数据回归出结果,再与大崎顺彦的结果作对比。与大崎顺彦的结果虽有差异,但随阻尼比、震级的增大而基本趋于一致。新的转换关系将为《核电厂抗震设计规范》、《建筑抗震设计规范》、《电力设施抗震设计规范》等相关规范的制订和修改提供参考。

| Abstract: | Transfer relationship among response spectra with different damping ratios has found applications in different kinds of seismic design codes of China.Using the transfer relationship proposed by Ohsaki as the mathematical model and based on 260 bedrock records containing reliable long-period information,a new transfer relationship among response spectra with different damping ratios in the natural period range from 0.04s to 10.0 s is obtained by regress analysis.This new transfer relationship not only makes ... |
