A new mathematical formulation is presented for the analysis of eccentrically stiffened plates, subjected to the combined or separate actions of lateral and in-plane loading. The formulation covers angle and tee section stiffeners as well as rectangular flats. Both material and geometric non-linearities are considered and the governing equations are solved numerically by the application of dynamic relaxation to their finite difference equivalents. Plasticity in the plate is assumed to be governed by a full depth yield criterion, while in the stiffeners, a multilayer approach is adopted. Numerical solutions are presented for a series of plates stiffened by flats, for a wide range of panel slenderness ratios and stiffener rigidities. The effects of initial deformation, combined lateral and in-plane loading and the use of hybrid plates are also investigated. (Author/TRRL)
