Seismic observation analysis and validation of seismic response analysis model for the nuclear facilities

Choi, B.; Nishida, Akemi

no journal, ,

To validate analysis models against actual phenomena is an important issue in improving the reliability of the seismic safety evaluation. In this work, firstly, we analyze seismic observation records in the target Nuclear Power Plant (NPP) building. In order to validate three dimensional finite element models of the target plant, seismic response analyses using the same input waves as the records are conducted, and a Fourier amplitude ratio of the response acceleration on each floor is compared between the analysis and the observation. By introducing the Fourier amplitude ratio between different floors, the amplification of the response acceleration is quantified, and more detailed comparisons between the analysis results and the observation records are enabled. Through this comparison, it is confirmed that in the analysis results, the amplification of the response acceleration at the frequency ranges of 3-4 Hz (primarly mode) and 8-9 Hz (secondary mode) is consistent with the observation records.
