ULTIMATE STRENGTH OF LONGITUDINALLY STIFFENED PLATES SUBJECTED TO TRANSVERSE COMPRESSION

Abstract

This paper deals with the ultimate strength of transversely compressed plate with longitudinal stiffeners. Firstly, the influences of initial deflection, residual stress and patterns of stress distribution on the ultimate strength of the stiffened plate are investigated analytically. Then, an approximate method is proposed for predicting the ultimate strength of stiffened plate, through a parametric study by means of the elasto-plastic and finite displacement analyses. Finally, this approximate method is verified in comparisons with numerical and experimental results.
