ABSTRACT:

The aim of the present study is to investigate the effects of uniform corrosion on the load-carrying capacity of steel beam sections. In this paper, a credible corrosion model for damaged steel beams has been developed based on the real existing data. Thickness loss data were compiled from corrosion damaged samples beams which picked up from a petrochemical industry. The developed deteriorated model was employed to demonstrate the effects of uniform corrosion on the structural behavior of damaged steel beams due to uniform corrosion wastage. It was found from the obtained results that the lateral distorsional buckling is the critical failure mode at the preliminary age of corrosion wastage.
