Abstract：The pump building of CPR1000 nuclear power plants as seismic category I structure, the calculation of earthquake action under the ultimate safety ground motion(SL-2) is the very important part for the pump building structural design and the stability analysis. With the recent development of soil-structure interaction(SSI) analysis, comparative analysis of earthquake action is carried out based on the lumped parameter models recommended by seismic design codes of ASCE4-98 which is applicable to the homogeneous site and massless foundation model and viscous-spring artificial boundary model which are especially fit for the non-homogeneous site. Finally, the rule of the earthquake action with different sites and the different dynamic numerical site models for this certain lumped mass model of pump building is summed up. This paper provides some reference and guidance significance in the aspect of the structural design and the stability analysis.
