The influence of corrosion damage on the stability of eccentrically compressed elements

The article analyzes the causes of corrosion and assesses its impact on the stability of extra–centric compressed elements. The characteristic causes of corrosion damage in steel columns are established. Calculations were performed according to the methodological basis set out in SP 16.13330.2017 “Steel structures” and based on the first limit group of limit States. The results of the calculation determined that the defeat of a continuous uniform corrosion account for over 50% of the cross section, on the basis of what you accept of eccentrically compressed rod emergency.

We recommend performing amplification or replace damaged elements in case of insufficient load–bearing capacity.
