EVALUATION OF THE EFFECTS OF DIFFERENCES IN BUILDING MODELS ON THE SEISMIC RESPONSE OF A NUCLEAR POWER PLANT STRUCTURE

抄録

This study examines two different seismic response analysis models of a nuclear power plant building, including the three-dimensional finite-element (3D FE) model with shell elements and the conventional sway-rocking model. Further, the results obtained using these models are compared for estimating the effects related with the differences between the modeling methods. In addition, the authors analyzed the spatial variations of the response results based on the merits of the 3D FE model, and the potential applications of this information are discussed.
