The main objective of this paper is to analyze the r('ctangular stiffened plates with two opposite ends
elasti cally restrained and t he others simply supported subjected to in-plane bending by Finite Element
κ1ethod. Another objecti ve is to develope Classical Method analyzing the unstiffened rectangular plates
with the above boundary conditions. In order to validate finite element and classical methods, the buck ,
ling strengths of the rectangular plates with four simply supported ends, and with two simply
supported and the others fixed ends by fini te element method and classical method are compared with
those of references. In finite element method, elas tically restrained ends can be obtained as considering
torsional and warping rigidities of end stiffeners. The buckling strengths of the rectangular plates with
elastically restrained ends by finit e element and classical methods are calcu lated and compared with
each other.In case of stiffened plates, to validate finite elernent rnethod, the buckling strengths of the rectangular
stiffened plates with four sirnply supported ends, and with two sirnply supported and the others
fixed ends are also cornpared with those of references. The buckling strengths of the rectangular
stiffened plates with elastically restrained ends by finite elernent rnethod are calculated as solving
eigenvalue problerns which are obtained as assernbling rectangular plate elernents and bearn elernents
considered torsional and warping rigidities. The buckling strengths of rectangular stiffened plates according
to various positions of rectangular intermediate stiffener, J and 1" of end stiffeners are also
obtained, which are cornpared to deterrnine the efficient position of interrnediate stiffener.
