| Abstract: | The factors which influence the seismic responses of nuclear engineering structure include the properties of earthquake,soil and structures.In this paper,for the purpose of the reactor building of nuclear station,the influence of the floor response spectra possessing multi-damping and other seismic responses of nuclear reactor building under the condition of inhomogeneous foundation soil is investigated by considering the soil-structure interaction(SSI).Seismic responses of reactor are calculated by using SUPERFLUSH/2D software,the finite element model of foundation is made by utilizing ANSYS;the finite element model of reactor based on lumped-mass model is constructed by using SUPERFLUSH/2D.In the finite element method,the energy transfer boundary conditions at the bottom and sides of the model can be considered.The wave energy is transferring at the bottom of model.The wave dispersion fluctuation appears on both sides of model.The influence of foundation inhomogeneity on the floor spectra,maximum relative displacement and maximum acceleration of the nuclear reactor building is revealed by the numerical simulation,which provides a theoretical reference for structural design of nuclear reactor plant. |
