“…It can be seen that the columns D3H20-C360A, D4H20-C360B, and D4H20-C360C possessed the highest percentage error when using the equations of Hebor et al [1] and Nazari et al [2]. These columns have the same corrosion height of 20 mm, which is less than the half-wavelength of buckling.…”

“…Corrosion is one of the main contributors in the decrease of the structural performance of steel structures and develops in various outdoor conditions, such as rural, urban, and marine environments. Due to the low drag resistance and ease of handling during construction of tubular members, it is generally used in offshore structures as structural elements [1][2][3]. Corrosion causes reduction in cross-sectional area of steel tubular members, making it prone to local buckling, and may lead to compressive failure [4][5][6].…”

Corrosion is considered as one of the main factors in the structural performance deterioration of steel members. In this study, experimental and numerical methods were used to assess the reduction in compressive strength of short tubular steel columns with local corrosion damage. The corrosion damage was varied with different depths (0, 1.5, 2, 3, 4, 4.5, and 6 mm), height (0, 20, 40, 60, 80, 100, 120, 140, 160, and 180 mm), circumference (0, 90, 180, 270, and 360°), and location along the column. A parametric numerical study was performed to establish a correlation between the residual compressive strength and the severity of corrosion damage. The results showed that as the corrosion depth, height and circumference increased, the compressive strength decreased linearly. As for the corrosion height, the residual compressive strength became constant after decreasing linearly when the corrosion height was greater than the half-wavelength of buckling of the short columns. An equation is presented to evaluate the residual compressive strength of short columns with local corrosion wherein the volume of the corrosion damage was used as a reduction factor in calculating the compressive strength. The percentage error using the presented equation was found to be within 11.4%.

“…Mahammad et al (2012) considered plate buckling and post-buckling behavior and proposed a simplified effective thickness methodology to account for pit corrosion affecting one side of a plate. For steel tubes, local corrosion effects on strength and buckling was studied in Nazari et al (2014). Paik et al (2004) studied ultimate strength of plates with pit corrosion.…”

This paper presents numerical results of stress concentration factors for plates perforated by corrosion. Evidence from 25 plates with corrosion perforation considered show that typical shapes may be characterized as a deviation from an ellipse or from a circle. In order to model typical perforations created by this type of corrosion, holes with non-circular boundaries have been considered in the form of cosine shape and variations from it. Two load cases are investigated: uniaxial and shear stress fields in an elastic plane stress problem. The influence of the amplitude of deviation with respect to an ellipse or circle and the local curvature of the internal boundary of the hole are studied. A simplified model of an equivalent ellipse originally proposed by Nishida is shown to provide good estimates for stress concentration factors for a range of shapes induced by corrosion.
