中文摘要：

日本＂3.11＂大地震记录波中的MYG004波是迄今为止记录到的地面峰值加速度最大的地震波。文章在调整MYG004波加速度峰值后,从加速度反应谱、比能密度、输入能能量谱三个角度将其与一组常用地震动加速度时程作对比,分析其频谱特性;并通过一个8层某框架结构的弹塑性时程分析,进行验证。

英文摘要：

MYG004 is the strongest earthquake record derived in the Tohoku earthquake in March 11th,2011,which is also the most powerful record in the history.After the peak acceleration adjustment,the MYG004 record is compared in terms of acceleration response spectrum,specify energy density（SED） and input energy spectrum with a set of common earthquake records which are also adjusted in acceleration.Through the comparison,some spectrum feature of MYG004 are analyzed which are verified by a following elasto-plastic time-history process of a virtual 8-story frame and some actual earthquake damages.
