Equations of motion have been deduced for a plate strengthened with an orthogonal framework of ribs, taking into account the discrete placing of the ribs. An accurate solution of these equations has been obtained for the case when the plate reinforced with the ribs placed along one of the co-ordinate directions. For the plate strengthened with one longitudinal rib the influence of discrete placing of this rib and its rigidity on the magnitudes of the wave parameters of the harmonic waves propagating along the plate was studied by the numerical example.

There are presented obtained from literature review formulations which involve the loads and strains for evaluation of structural intensity for beams, shells and plates. The method of intensity evaluation was based on complex modal analysis with use of finite element method. There are presented results of structural intensity vectors distribution on the surface of simply supported, ribbed rectangular plate. Such solved problem was intended to show the usability of structure surface intensity method in diagnostics of construction joints.
