Plates resting on a subsoil are often met in constructions of the civil engineering. The main aim of the paper is twofold. Firstly, to propose a new averaged model of medium thickness plates resting on a periodic Winkler’s 3D subsoil, based on the non-asymptotic tolerance averaging technique, cf. Wozniak and Wierzbicki [19]. The main feature of the model is that it describes the effect of period lengths on the overall behaviour of the plate. Secondly, to apply the non-asymptotic model to analyse free vibrations of a plate strip on a periodic subsoil and show that the aforementioned effect plays a crucial role in dynamic problems.

Key words: medium thickness plate, periodic Winkler’s subsoil, effect of period lengths.
