This study presents an approach, based on correction coefficients, by which bending moments in rectangular plates when obtained by the elastic scheme method, can be calculated more accurately. At first, the well-known generalized coefficients, used in the elastic scheme method, and also taken from different literature sources are juxtaposed. The correction coefficients are obtained by the FEM according to the thin elastic plate theory. On the next stage, by looking into the shear deformability of the plate cross-section, the values of these coefficients are provided in a more accurate manner. The research has been done for a quadratic plate, but the aforenamed approach can be used to investigate any general rectangular plate, as well.
