3D forced vibrations of two-layered plates under an influence of periodic in time tangential actions were studied. An asymptotic solution of the corresponding 3D problem of the theory of elasticity was obtained. The problem, in particular, models the seismic actions on the base-foundation of structures. All components of the stress tensor and displacement vector were determined. It is shown, that among these quantities tangential ones play the leading role. Cases, when found solution becomes mathematically exact, were indicated.
