Abstract
In case of plated structures under compressive loading, their final buckled pattern involves a localized deformation in contrast to the periodic deformation pattern associated with the critical buckling mode. The experiment under cyclic loading showed that the strength as well as the ductility of plated structures deteriorate considerably due to this localized deformations of structural components. This implies that the localization of buckling patterns has an unfavorable effect on the earthquake resistance. Herein, we investigate the localization behavior of rectangular plates under uniaxial in-plane load, including that under cyclic loading. In addition to the perfect plates without initial imperfections, plates with initial deflections and residual stresses are analyzed to examine their effect on the localization behavior.
