“…To verify the expanded shear buckling reduction factor for maintenance and inspection of web panels, the sectional damage of the web plate used in shear loading tests was calculated and compared to the suggested shear buckling resistance equations [3,12]. Figure 10 shows the comparison between the suggested shear buckling resistance equations and the test results.…”

“…Therefore, the lower region of a web panel and a stiffener on a bearing are the main components that should be examined for residual strength or local structural behaviors when conducting research on corrosion problems focused on end girders. A lot of research on the structural behaviors of web panels with lower regional sectional damage has been carried out to examine the shear buckling resistance and shear buckling behaviors [1][2][3][4][5][6][7][8][9][10][11][12]. Many researches were conducted in Japan, where there are severe corrosion environments and many old structures [2,4,10,11].…”

This study deals with the relationship between imperfections and shear buckling resistance of web plates with sectional damage caused by corrosion. To examine the imperfection effect on the shear buckling resistance of a web plate with sectional damage, a series of nonlinear finite element (FE) analyses were carried out for a web plate with sectional damage, which was assumed as local corrosion damage. For considering imperfections of the web plate in the girder, initial out-of-plane deformation was introduced in the FE analysis model. Using the FE analysis results, the changes in the shear buckling resistance of the web plate with sectional damage were quantitatively examined and summarized according to the aspect ratio, boundary conditions, and height of the damaged section of the web plate. The effects of web imperfections on the shear buckling resistance were evaluated to be little compared to that of the web plate without sectional damage. The shear buckling resistance was shown to significantly change in the high-aspect-ratio web plate. A simple evaluation equation for the shear buckling resistance of a web plate with sectional damage was modified for use in the practical maintenance of a web plate in corrosive environments.

“…For the steel component, the effective cross-section area will be reduced because of the corrosion issue. The resistant property of the component is weakened, correspondingly [9][10][11]. Besides, corrosion issue results in the stress concentration, which reduces ductility of the steel component.…”

“…The decreases in resistant properties were quantified through the experiment, numerical simulation and theoretical analysis. However, existed studies were mostly based on the mild steel components [9,10,[18][19][20][21]. The investigation of the adverse effect of corrosion issue on the HSS is relatively limited [22].…”

Corrosion Effects on Mechanical Properties of Q620 High-Strength Steel

High-strength steel (HSS) is widely used in engineering structures, with its superior material performance. Corrosion issue tends to occur in steel structures with time. Corrosion effects on mechanical performance of Q620 HSS were investigated experimentally. The electrochemical accelerated corrosion test was conducted to get corroded Q620 HSS specimens (ρ = 0 ~ 60%). With increases in corrosion degree, corrosion performance became more and more non-uniform. The tensile coupon test was conducted to clarify mechanical properties of corroded Q620 HSS specimens. With increases in corrosion degree, fy, fu, εu and E decreased, correspondingly. The effect of corrosion on εy could be ignored. With the deepening of corrosion, the necking of Q620 HSS specimens was weakened, which reduced the ductility. Based on the numerical fitting, the relationship between corrosion degree and mechanical properties was clarified.

“…Chen et al [13] used finite element analysis (FEA) to investigate the failure processes of high-strength pipelines with single and multiple corrosions and produced an assessment procedure to predict the failure pressure of a pipeline with multiple corrosions. Jin et al [14] used FEA in considering the shear buckling behavior of a web panel with pits and through-thickness corrosion damage, and found that through-thickness corrosion damage significantly decreased the critical buckling load.…”

Corrosion deterioration of steel can heavily degrade the performance of marine and offshore structures. A typical steel protective device, which has worked for a dozen years in a river estuary, is selected as the research object. Its current corrosion response is measured on site and its further corrosive response is predicted based on measurement data and the structure's current state. Nonlinear finite element method is utilized to analyze the degradation of the protective device's anti-collision performance. Meanwhile the rubber buffer effect has been investigated for its anti-collision on the protective device. A prediction method is proposed that can accurately forecast degradation of the anti-collision performance of a protective device as time progresses.
