Empirical prediction equation of inter-period correlations of response spectrum used in seismic design and seismic probabilistic risk assessment (SPRA) have been developed by regression analysis of multiple observational records, including multiple sites and multiple seismic sources. In this study, to evaluate the inter-period correlation of the response spectrum at a specific site when a specific earthquake occurs, we evaluated the inter-period correlation based on the response spectrum calculated by the strong ground motion simulation, and considered its characteristics.
