Local Buckling of Longitudinally Stiffened Curved Plates

Design information is presented on the buckling strength of longitudinally stiffened curved plates. Design charts for determining the buckling strength of flat plates stiffened longitudinally by Z-section stringers are given for plate and stiffener proportions representative of stiffened curved plates and a semiempirical procedure is suggested from which the effect of curvature on the buckling strength of the plate can be determined.
