Effect of corrosion on the buckling of steel angle members - experimental study

Abstract

The aim of this work is to study the effect of corrosion on the buckling behaviour and resistance of corroded steel angle section members. The influences of the corrosion location and the loss of cross-section are studied by experimental investigations, where the corrosion is modelled by artificial thickness reduction. Compressive buckling tests are carried out on twenty-four specimens. Different corrosion damages are modelled, like uniform, pitting and local corrosion in the specimens. The buckling behaviour and the relationship of the corrosion reduction and the resistance decrease are determined.
