Abstract:Based on previous experimental results of the low cycle behavior of corroded reinforced concrete members subjected to eccentric compression, this study proposes the relation between hysteretic consumption and rebar corrosion rate. By analyzing the deformation of corroded reinforced concrete members with pushover method, the relation of rebar corrosion rate and elastic-plastic deformation is investigated with the skeleton curve restoring model of corroded members proposed previously by authors. Analysis results indicate that deformation of reinforced concrete members nonlinearly increases with the increase of rebar corrosion rates. The greater the earthquake intensity, the faster the increase of structural deformations with rebar corrosion rate. Within specified structural deformations, the bearing capacity of structures nonlinearly degrades with the increase of rebar corrosion rate.
