Stuctural FEM analysis on railway car bodies made of aluminium hollow extrusions under uniformly distributed normal load was carried out. For the structural analysis on hollow extrusion structure car body, the method to substitute equivalent orthogonal anisotropic plates for hollow extrusions and the character of shell elements must be considered. The equivalent orthogonal anisotropic plate is obtained through the selection of four main rigidities which describe principal deformation of car body. For the characteristics of shell elements, element division on pier panel enough to describe its shear deformation must be considered. The FEM result which is calculated with orthogonal anisotropic plates and the characteristic of shell elements are in good agreement with the load test result.
