“…Since, actual imperfections were not measured in this study, an average initial deflection value equal to 0.1β 2 as proposed by Smith et al (1988) and used by other researchers (Khurram et al, 2014;Ok et al, 2007;Paik and Kim, 2002) was utilized in the present study. The (1)…”

“…Generally, three different types of the failure modes, normal buckling, crippling and crushing are observed from the FE analysis (Khurram et al, 2014). Buckling of the web occurs with out-of-plane deformation over most of the depth of the web whereas, crippling is localised buckling of the web in the presence of plasticity and crushing is local yielding of the web without any buckling.…”

“…In real cases corrosion yields irregular damages on steel structures however, for the simplicity a uniform rectangular type of the damage is usually incorporated in FE analysis for the simulation of corroded plate under uniaxial compression as ultimate strength of plates under compression is governed by the smallest cross-sectional area (Ok et al 2007, Khurram et al 2014.…”

“…Khurram et al (2013) proposed some empirical relationships to estimate the residual shear capacity of the plate girder affected by the end panel corrosion and also suggested that the average thickness loss may be used to model the local corrosion damage in the numerical study. As for bearing capacity is concern in his earlier study the Khurram et al (2014) proposed a damage parameter named reduced thickness ratio to predict the failure mode of plate girder end against the bearing load.…”

The present study deals with the effect of uniform and non-uniform local corrosion damages at the bearing stiffener and nearby web on the bearing capacity of plate girder. Five plate girder ends simulated with different uniform and non-uniform types of corrosion damage, at the base of the bearing stiffener are used in the experimental program. The experimental results are modeled and verified on a Finite Element (FE) software ABAQUS, considering shell-solid coupling elements formulation. The study is further extended to various damage cases i.e., stiffener damage, stiffer plus web damages etc. considering different damage heights and residual thicknesses. The study concludes that minimum thickness within any damage height may be used to simulate the corrosion damage in a FE analysis. At the end, some empirical relationships are also proposed to estimate the bearing strength of the plate girder affected by the local corrosion damage at plate girder end.
