Inelastic Buckling Strength of Plates with Residual Stresses under Bending

Abstract

Recently, the effect of residual stresses on local buckling strength has been drawn their attensions of engineers in the field of steel structures. One of the authors has conducted the research to clarify the role of the residual stresses on buckling of plates under compression, and shear and presented several papers from which important effects were recognized especially for shear buckling. In this paper, the results of theoretical and experimental investigations into inelastic buckling of plates with residual stresses, including webs of built-up I-sections, under bending were presented. The result suggests that the effect of residual stresses is not so important on buckling of the plates in case of pure bending especially for webs of built-up I-sections.
