Abstract

 Severe corrosion damage in steel bridges has been found in spite of bridge maintenance through anti-corrosion coating and painting. It is especially easy for severe corrosion damage to occur around the support of steel plate girder bridges. The shear strength of steel webs can be decreased by locally corroded panels in the steel plate girder bridge. In this study, shear strengths and post-buckling behaviors of the steel web with locally corroded panels were examined according to corrosion conditions. For this purpose, shear buckling behaviors of shear loading test specimens were identified and evaluated by nonlinear finite element (FE) analyses. Shear buckling strengths of the locally corroded web panels were quantitatively evaluated according to corrosion damage and boundary conditions. In addition, the simple shear strength estimation method was proposed for locally corroded web panels.
