In this paper, a numerical study was done to estimate the ultimate seismic condition of a typical PWR-type nuclear reactor building by modeling the actual building as faithfully as possible by 3-dimensional FEM taking the nonlinear characteristic of RC wall into consideration in detail. First, on the basis of the design level earthquake ground motion, the damage situation and the bearing force of the building were grasped by loading multiplied ground motion. Moreover, the same analysis was performed also by the lumped-mass model which is used in the current design of nuclear power structures, and both results were compared.
