Abstract:At present, the seismic safety analysis of nuclear power structures only
   use some simple numerical models recommended by various specifications,
   or the basic finite element model with viscous-elastic boundary, and
   there is no relatively high precision analysis method. A high precision
   multi-transmission formula model with artificial boundary on the basis
   of the implicit-explicit coupling integral method is introduced in this
   paper, and a directly numerical algorithm scheme on the framework of
   ANSYS is proposed, which particularly is applicable for the dynamic
   interaction analysis of complex factory building structures of nuclear
   engineering. And then, the validation and applicability of this new
   method is verified using a practical example. Numerical results proof
   that the proposed model is applicable for the finite element analysis of
   the dynamic response of nuclear power plant buildings.
