摘　　要： 本文提出了双规准反应谱的概念。在统计了美国西部大量强震记录的基础上,分别研究了规准反应谱和双规准反应谱的特性,并进行了详细的对比分析。研究结果表明,双规准反应谱比通常的规准反应谱有更好的规律性,这不仅有利于认识地震动的特性,还可使基于场地的抗震设计反应谱大大简化,更便于广大工程设计人员应用。 A concept of bi-normalized response spectra was presented in this paper. Based on the statistical analysis of a large number of earthquake records collected from the western America, the conventionally normalized response spectra and bi-normalized response spectra were studied and compared respectively. It is concluded that the (bi-)(normalized) response spectra have better consistency among all strong motion records than the conventionally (normalized) response spectra. It implies that the bi-normalized response spectra can be used not only in revealing the (characteristics) of strong ground motions but also in simplifying the site specific design spectra for engineering design purpose.
