Abstract : An analytical investigation of the ultimate strength of longitudinally stiffened plate panels having large plate width to thickness ratios (plate buckles before the ultimate axial strength of panel is reached), and subjected to combined axial and uniformly distributed lateral loads is presented. Of interest in this study are stiffened panels as used in ship bottom plating. The emphasis is placed on the effect of lateral loads, residual stresses and b/t ratio on the ultimate axial strength of the panels. The results were obtained numerically on a digital computer. The following effects on the ultimate axial load were established: (1) Lateral loads cause a significant reduction. (2) Compressive residual stresses in the plate have reducing influence. (3) A large postbuckling strength can be expected for panels with large plate width to thickness ratios. A comparison between the analytical and test results shows that the method of analysis developed in this study can predict the ultimate strength of stiffened panels with relatively good accuracy.
