| Research Abstract |
The non-destructive testing and structural performance evaluation of steel members corroded on the boundary with concrete were investigated. In the experimental results, it was shown that damping of steel members was gained by corrosion between steel and concrete boundary. Moreover, the reversed cyclic loading tests of the steel columns specimens were conducted. The ductility and energy absorption capacity of the steel columns were significantly decreased by the steel corrosion on the concrete boundary.
