| 摘 要： | 利用台湾SMART－1台阵的数字强震仪加速度记录分析了同类场地上的地震动长周期分量特性，结果表明：同一次地震震中距基本相同的同类场地加速度反应谱短周期部分有较明显的差别，长周期部分则基本相同；震级和震中距对短周期反应谱影响明显，对长周期反应谱也有一定影响。最后将SMART－1台阳场地的平均谱与新的建筑抗震设计规范修订稿中提出的设计反应谱作了比较。

| Abstract: | Long period features of strong motion on the same kind of sites are analysed using the records of digital accelerographs deployed in SMART-1 Array of Taiwan. Although the differences of epicentral distances for different stations are small for the same earthquake,the short period spectral components of accelerograms are different obviously, while the long period spectral components are same mainly. The effects of magnitude and epicentral distance on long period spectral components are not so stronger as for short period components Finally, The average spectrum for SMART-1 Array of Taiwan is compared with the design spectra of the new seismic design code of buildings |
