In this paper, the modeling error for the NPP building fragility evaluation in the strong nonlinear area of the seismic response model is investigated. In the study, the restoring characteristic model of the RC bearing wall used for the response analysis of the lumped mass model was focused. 7 parts where the nonlinear level is expected to be strong during the strong earthquake in typical nuclear reactor buildings were extracted, then seismic response analysis using the model were conducted and the fragility curves were calculated. Comparing with the results of FEM model, the modeling error (βu_N) was estimated about 0.1.
