Correlation Analysis of JNES Seismic Wall Pressure Data for ABWR Model Structures

摘要

To investigate the applicability of existing seismic soil-structure interaction (SSI) computer codes to deeply embedded and/or buried (DEB) structures, Brookhaven National Laboratory (BNL) performed a correlation analysis. The correlation analysis was performed using recorded earthquake response data from tests conducted by the Nuclear Power Engineering Corporation (NUPEC) of Japan. The NUPEC tests used 1/10th scale models, based on outer structural dimensions similar to the advanced boiling water reactor (ABWR) building structures. The ABWR models were embedded below grade to approximately 50% of the overall height of the model. The NUPEC earthquake response data were provided by the Japan Nuclear Energy Safety Organization (JNES, successor of NUPEC seismic test data) as part of the US-Japan collaborative effort in the area of seismic engineering research. The computer programs used in the correlation analysis are the System for Analysis of Soil-Structure Interaction (SASSI) and LS-DYNA programs, which represent the sub-structuring sub-traction and direct finite element methods. An assessment of the SASSI and LS-DYNA programs was made based on the insights gleaned from the correlation results.
