The special orthotropic plate theory is used for analysis of panels made of plate girders and cross beams. The cross-sections of cross-beams are WF types. The result is compared with that of the beam theory. According to the numerical examination given in this paper, the result by the plate theory is 2.43 times stiffer than that of beam theory.
