Abstract

The atmospheric corrosion is the main reason of behavior deterioration of space steel structure under service, especially in wet and coastal area. The circular steel tube was widely used in space steel structure, the behavior deterioration of which caused by corrosion has great influence to the structure safety. In this paper 19 kinds of circular steel tube were chosen to study based on the corrosion data of Qingdao. Based on the power function corrosion model, the corrosion simulation program and analysis of tube surface corrosion was done by ANSYS, and the rule of bending stiffness deterioration caused by corrosion with time change for 50 years was obtained, which shows that after 50 years the deterioration of thinner tube bending stiffness will exceed 10 percent, and with the wall thickness increasing, the deterioration will became not obvious.
