| 摘 要： | 文章提出了采用结构地震破损指数为依据，对地震强度指标定义有效性开展客观评价的建议。介绍了目前主要地震强度指标的定义，选择了一钢筋混凝土框架结构，输入１７条地震波，利用结构非线性动力分析进行了地震反应及破损的数值模拟。根据计算结果，探讨研究了结构地震破损与地震强度指标的相关性，揭示了客观评价地震强度指标定义的可能途径。

| Abstract: | The suggestion to evaluate the earthquake intensity indices based on the structural damage index is put forward by the author. Some current earthquake intensity indices are presented. Nonlinear dynamic analysis is made for a reinforced concrete frame structure under 17 input earthquake waves. Based on the results of numeric simulation of the structural earthquake response and damage, the relativity between the earthquake intensity indices and damage index is investigated. A possible effective way to evaluate the earthquake intensity indices is shown. |
