| 摘 要： | 在分别统计了美国西部强震记录与我国强震记录的基础上，研究了规准反应谱和双规准反应谱的特性，并将规准反应谱与双规准反应谱以及两国记录的平均双规准反应谱进行了对比分析．研究结果表明，不仅不同场地上的双规准反应谱十分接近，而且不同地震地质环境下的双规准反应谱也基本相同，双规准反应谱比通常的规准反应谱更能反映地震动反应谱的规律性．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谱大大简化．

| Abstract: | A concept of bi-normalized response spectra is presented . Based on the statistical analysis of strong earthquake ground-motion records collected from the western America and China, the conventionally normalized response spectra and bi-normalized response spectra for the various geological sites were studied and compared respectively. It concluded that the bi-normalized response spectra have much better consistency among all strong motion records than do 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. |
