Soil-Structure Interaction Analysis of RBMK-1000 MW Type NPP for SeismicEvent

摘要

This paper presents the results of study of the structural response of Leningradskaya Nuclear Power Plant (LNPP)RBMK-1000 MW Reactor Building to seismic excitation motion. A 3-D detailed structural model was developed for theseismic response analyses of the building. The structure was assumed surface founded at the basemat level. Seismic responsesoil-structure interaction (SSI) analyses were carried out considering shear wave propagation pattern for the input motion.The in-structure time histories and response spectra were generated in referenced locations. Conclusions are drawn for thereliability of the structural response evaluation considering the soil-structure interaction effects.
