The compressive buckling stress of a rectangular flat plate is given by Equation (6-1). Fcr = ¯ k 2E 12(1 2e) (t b)2. (6-1) The relation is applicable to various types of loadings in both the elastic and the inelastic ranges and for various conditions of edge fixity.

4.2 ELASTIC LOCAL BUCKLING OF FLAT PLATES An examination of the buckling behavior of a single plate supported along its edges is an essential preliminary step toward the understanding of local buckling behavior of plate assemblies. The buckling stresses are obtained from the concept of bifurcation of an initially perfect structure. Elastic buckling of stiffened panels in ships under bi ABSTRACT This paper focuses on the elastic buckling strength of typical stiffened panels under bi-axial compression. Three levels of assumptions for stiffeners are investigated:(1) Vlasov assumption; (2) stiffeners web plate assumed deformable; (3) both stiffeners web and flange plates assumed deformable.

There has been a great deal of testing and investigations on this matter and in the last decade also unstiffened flanges and webs of beams were included in this technique by the codes.

Stiffness requirement for flat-bar longitudinal stiffener

In this paper, the moment of inertia requirement of flat-bar longitudinal stiffener of bottom flange in steel box girder is investigated through finite element modeling. The required minimum stiffness for longitudinal stiffeners of box girder flange is given in the AASHTO LRFD Bridge Design Specification and is modified by Yoo. However, this requirement is adopted for T-shape stiffeners.Annex A:Buckling and Ultimate Strength of Flat PlatesThe critical stress of the stiffened plate is given by:cr pp k Et, b 2 2 2 12 1 (A.7) where b is the total plate width.
