Research Abstract

In this research, the ultimate shear strength of steel plate girders composed by corroded web plates with different corrosion patterns are investigated. The tests on the girder models with the full scale original forms of corroded web plates have been carried out in order to assess the influence of different corrosion patterns on the strength. A parametric study using nonlinear finite element approach is also conducted to evaluate the effects of different corrosion patterns on the strength. The influence on the ultimate shear strength of the corrosion patterns is also discussed together with the failure patterns observed during tests and analytical results.
