Finite element modelling of electric cabinets in nuclear power plants: a review

Abstract

The development of numerical modeling for safety-related cabinet facilities plays an essential role in seismic risk assessment. For nonlinear time history analysis, a full finite element model is often time-consuming due to its computational complexity. A simplified model can significantly reduce modeling complexity, however, the dynamic characteristics (such as mass, local mode shapes, or nonlinear behavior) are not fully captured. The current paper presents an overview of the current literature addressing the development of cabinet modeling. The results are expected to serve as a general reference and starting point to new researchers.
