| 摘 要： | 本文在统计了大量强震记录的基础上,分别研究了双规准加速度反应谱和双规准速度反应谱的特性,进行了对比分析,并分别得出了定量分析的结果。研究结果表明,双规准加速度反应谱在短周期段有很好的统一性,而双规准速度反应谱在长周期段的统一性较好,这种规律性对于认识地震动的特性、改进抗震设计反应谱具有重要的意义。

| Abstract: | Based on a statistical analysis of a large number of strong motion records,the bi-normalized velocity response spectra and the bi-normalized acceleration response spectra are studied.The quantitative results are also given.It is concluded that the bi-normalized acceleration response spectra have better consistency in the short-period range,and in the long-period range the bi-normalized velocity response spectra have better consistency.It is significant for revealing the characteristics of strong motions and... |
