Saad-Eldeen, S., Garbatov, Y. and Guedes Soares, C. (2012), “Influence of Weld Toe Shape and Material Models on the Ultimate Strength of a Slightly Corroded Box Girder”, Sustainable Maritime Transportation and Exploitation of Sea Resources, E. Rizzuto & C. Guedes Soares, (Eds.), Taylor and Francis Group, pp. 401-409
The objective of this paper is to analyze the ultimate strength of a slightly corroded box girder subjected to four-point loading resulting in a constant vertical bending moment along the box girder, using non-linear finite element method. A series of nonlinear collapse analyses have been performed and the ultimate strength has been analyzed using different material models and also different weld toe shapes. Different elasto-plastic material models have been developed accounting for the residual stresses effect and post-buckling behavior. Comparisons between numerical and experimental results have been performed for the slightly corroded box showing a very good agreement.
