Performance and strength calculation of CFST columns with localized pitting corrosion damage

In recent years, concrete-filled steel tubular (CFST) columns are increasingly used in ocean construction, such as offshore towers and marine platforms. When used in harsh marine environments, the inevitable pitting corrosion poses a crucial threat to the outer surface of CFST and results in stress concentration, early local buckling as well as confinement reduction towards concrete. Relevant study is rarely seen given the complexity in...
