An approximate stiffness method for the elastic analysis is described for rectangular orthotropic plates that are two-way continuous over rigid supports. Levy-type displacement functions are used to derive stiffness matrices for full-size plate elements. Transverse loads are replaced by nodal line forces. The number of degrees-of-freedom (stiffness equations) needed for acceptable approximations is very low.
