The method of equivalent characteristicperiod is suggested in this article, thus to enable an easy application of evaluation results of seismic safety.
在对其进行分析研究的基础上,提出等效特征周期的方法,使一般的设计软件能方便使用地震安全性评价结果。

The ratio of vertical and horizontal predominant period is 0.7-0.9, so independent characteristicperiod of vertical design response spectrum should be defined.
But these researches all established on the stage of elasticity analysis, the same characteristicperiod of response spectrum was used for the stage of elastoplastic analysis.
