"Local buckling of stiffened and unstiffened curved elements has been investigated both experimentally and analytically. Stiffened curved elements are supported on all four edges while unstiffened curved elements are supported along three edges with one longitudinal edge free.
A series of stub column, beam, and shear tests have been performed for sections containing curved elements. The tested specimens were formed from sheet steels with yield strengths ranging from 27 to 88 ksi. The radius-to-thickness, R/t, values of the curved elements varied from 12 to 438 whereas the arc length-to-thickness, bit, ratios ranged from 23 to 218.
As a result of these tests and existing curved element theory, semi-empirical expressions have been developed for the prediction of local buckling, caused by uniform axial compression, for both types of curved elements. Approximate methods have been established for prediction of curved element local buckling caused by bending. Also, an approximate technique has been derived to predict the interaction between the local buckling of flat and curved elements.
A nonlinear finite element program has been successfully employed to predict local buckling of both stiffened and unstiffened curved elements when subjected to uniform axial compression"--Abstract, page ii.
