There are several techniques to build the lumped-mass stick model, which are tributary-area based conventional model, frequency adaptive model, and advanced model combining the conventional and frequency adaptive models. The present study is to compare the seismic response accuracy of the models including FE model. The target structure is a nuclear containment structure and 45 earthquake ground motions are considered for the seismic analysis. The results show that the advanced lumped-mass model provides similar and more consistent responses to the FE model, compared to other models.
