Dynamic partial uplift analyses of a structure on a 3-D layered half-space are performed based on the substructure method in the time domain The ARMA type recursive evaluations taking account of the causality of dynamic stiffness are used to enhance computational efficiency for calculation of interaction forces The dynamic response of a rigid foundation for harmonic excitations is first performed Then, the earthquake response characteristics of a nuclear reactor building taking account of the partial uplift are described for both linear and nonlinear cases of the building The effects of the partial uplift on the responses are discussed
