摘要: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 1 3 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 1 3 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.
