A box orthotropic rectangular plate structure is a structure made by four plates. To solve the free vibration problem of this structure, it may be analyzed by the method of general analytical solution. This solution can be used to solve the plate with arbitrary boundaries. For each plate there are boundary conditions at the top and the bottom. While at the edge connected between two plates there are continuous conditions. From equations caused by all of the conditions of four plates, it can be used to solve the natural frequencies and vibration modes. For solve all of the frequencies it may be make use of symmetric and antisymmetric conditions in deformation. For example, a rectangular and a square plate structure has been calculated and discussed.
