Abstract:
Due to the increasing numbers and expenses of steel structures in different countries, the study of their corrosion during the time that causes some problems in their members’ load-carrying ability, had been of fundamental importance. Considering the slight weight of eroded members and the depth of pits, the existence of pitting corrosion is a fundamental issue in the buildings. Firstly, in this study, the load-carrying capacity of thin-walled box-sections (four specimens with different dimensions) is examined. Then, assuming width-thickness ratio and section side ratio of each specimen to be variable, the effect of each parameter on the ultimate load-carrying capacity of system is observed. all models using modeling software ABAQUS. Finally, the aim of this paper is to examine the effect of corrosion on the ultimate load-carrying capacity of the above box-sections.
