摘要随着当前结构性能设计及耗能减震技术的普遍应用，根据合理的地震动强度指标来选择和调整实测地震动记录进行结构地震动响应分析,对于保证结构抗震设计的可靠性具有重要的意义。该研究将13种常用的地震动强度指标按照加速度型指标、速度型指标和位移型指标分为3类，对强震作用下13种常用的地震动强度指标与不同周期框架结构响应参数的相关性开展了研究。研究结果表明：3类地震动强度指标中，加速度型指标与短周期框架结构响应参数的相关性最好；速度型指标与中周期和中长周期框架结构响应参数的相关性最好；位移型指标与中长周期框架结构响应参数的相关性相对较好；同一结构在线性反应阶段与非线性反应阶段的响应参数与地震动强度指标的相关性是变化的。

Abstract：In the dynamic time-history analysis of frame structure, proper ground motion intensity indexes are required for selecting and modifying earthquake records. Here, the correlations between 13 ground motion intensity indexes and response parameters of frame structures with different periods were studied using a series of nonlinear dynamic time-history analyses. The 13 intensity indexes were classified as acceleration-related intensity index, velocity-related one and displacement-related one. Results showed that among the three kinds of ground motion intensity indexes, the correlations between acceleration-related intensity indexes and response parameters of frame structures with short periods are the best; the correlations between velocity-related intensity indexes and response parameters of frame structures with medium and medium-to-long periods are the best; the correlations between displacement-related intensity indexes and response parameters of frame structures with medium-to-long periods are better; the correlations between ground motion intensity indexes and response parameters of the same frame structure in the linear response stage and those in the nonlinear response stage are different.
