But these researches all established on the stage of elasticity analysis, the same characteristic period of response spectrum was used for the stage of elastoplastic analysis.
但这些研究多建立在弹性阶段分析的基础之上，对于弹塑性阶段的选波采用了与弹性阶段相同的特征周期。
The ratio of vertical and horizontal predominant period is 0.7-0.9, so independent characteristic period of vertical design response spectrum should be defined.
竖向与水平向地震动分量卓越周期的比值在0.7 - 0.9之间，竖向设计反应谱的特征周期应有单独规定。
