Influence of State of Rebar Corrosion on Mechanical Behavior of RC Member

Supervisor@Takumi@SHIMOMURA

In this study, the nonuniformity of rebar corrosion and corrosion crack width in concrete with respect
to longitudinal direction and the influence of the nonuniformity corrosion on mechanical behavior of
RC member were investigated. Based on the investigations, their mathematical models were
proposed. Relationship between longitudinal distribution of corrosion and crack width in the RC
specimen that had been corroded by electric current were examined. Uniaxial tensile tests were
carried out using RC specimens with different corrosion level and corrosion length. Influences of
nonuniform corrosion on tension stiffness of RC member were discussed.
