The author continues the chain of publications about the extension of the previously proposed combined asymptotic method of seismic SSI analysis for the multiply-supported structures. In this paper the dynamic stiffness matrix in the frequency domain condensed to the rigid contact surfaces is obtained for the two-base structure. Simplified structure modeling the NPP Reactor Building with transportation portal is considered. Accounting for the internal damping in different ways is also discussed.
