The author concludes 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 transfer functions from the free-field motion to the platforms’ motions under the basements are obtained for the two-base structure in the frequency domain. Simplified structure modeling the NPP Reactor Building with transportation portal is considered as a benchmark.
